In the past decade there has been increased interest in research on color and
psychological functioning. Important advances have been made in theoretical work and
empirical work, but there are also important weaknesses in both areas that must be
addressed for the literature to continue to develop apace. In this article, I provide brief
theoretical and empirical reviews of research in this area, in each instance beginning with
a historical background and recent advancements, and proceeding to an evaluation
focused on weaknesses that provide guidelines for future research. I conclude by
reiterating that the literature on color and psychological functioning is at a nascent stage
of development, and by recommending patience and prudence regarding conclusions
about theory, findings, and real-world application.

The past decade has seen enhanced interest in research in the area of color and psychological
functioning. Progress has been made on both theoretical and empirical fronts, but there are also
weaknesses on both of these fronts that must be attended to for this research area to continue to
make progress. In the following, I briefly review both advances and weaknesses in the literature on
color and psychological functioning.
Theoretical Work
Background and Recent Developments
Color has fascinated scholars for millennia (Sloane, 1991;Gage, 1993). Theorizing on color and
psychological functioning has been present since Goethe (1810) penned his Theory of Colors, in
which he linked color categories (e.g., the “plus” colors of yellow, red–yellow, yellow–red) to emo-
tional responding (e.g., warmth, excitement). Goldstein (1942) expanded on Goethe’s intuitions,
positing that certain colors (e.g., red, yellow) produce systematic physiological reactions manifest in
emotional experience (e.g., negative arousal), cognitive orientation (e.g., outward focus), and overt
action (e.g., forceful behavior). Subsequent theorizing derived from Goldstein’s ideas has focused
on wavelength, positing that longer wavelength colors feel arousing or warm, whereas shorter wave-
length colors feel relaxing or cool (Nakashian, 1964;Crowley, 1993). Other conceptual statements
about color and psychological functioning have focused on general associations that people have
to colors and their corresponding influence on downstream affect, cognition, and behavior (e.g.,
black is associated with aggression and elicits aggressive behavior; Frank and Gilovich, 1988;Soldat
et al., 1997). Finally, much writing on color and psychological functioning has been completely
atheoretical, focused exclusively on finding answers to applied questions (e.g., “What wall color
Frontiers in Psychology | www.frontiersin.org 1April 2015 | Volume 6 | Article 368
Elliot Color and psychological functioning
facilitates worker alertness and productivity?”). The aforemen-
tioned theories and conceptual statements continue to motivate
research on color and psychological functioning. However, sev-
eral other promising theoretical frameworks have also emerged
in the past decade, and I review these frameworks in the
following.
Hill and Barton (2005) noted that in many non-human
animals, including primate species, dominance in aggressive
encounters (i.e., superior physical condition) is signaled by the
bright red of oxygenated blood visible on highly vascularized bare
skin. Artificial red (e.g., on leg bands) has likewise been shown to
signal dominance in non-human animals, mimicking the natural
physiological process (Cuthill et al., 1997). In humans in aggres-
sive encounters, a testosterone surge produces visible reddening
on the face and fear leads to pallor (Drummond and Quay, 2001;
Levenson, 2003). Hill and Barton (2005) posited that the parallel
between humans and non-humans present at the physiological
level may extend to artificial stimuli, such that wearing red in
sport contests may convey dominance and lead to a competitive
advantage.
Other theorists have also utilized a comparative approach in
positing links between skin coloration and the evaluation of con-
specifics. Changizi et al. (2006)andChangizi (2009)contend
that trichromatic vision evolved to enable primates, including
humans, to detect subtle changes in blood flow beneath the skin
that carry important information about the emotional state of
the conspecific. Increased red can convey anger, embarrassment,
or sexual arousal, whereas increased bluish or greenish tint can
convey illness or poor physiological condition. Thus, visual sensi-
tivity to these color modulations facilitates various forms of social
interaction. In similar fashion, Stephen et al. (2009)andStephen
and McKeegan (2010) propose that perceivers use information
about skin coloration (perhaps particularly from the face, Ta n
and Stephen, 2012) to make inferences about the attractiveness,
health, and dominance of conspecifics. Redness (from blood oxy-
genization) and yellowness (from carotenoids) are both seen as
facilitating positive judgments. Fink et al. (2006)andFink and
Matts (2007) posit that the homogeneity of skin coloration is an
important factor in evaluating the age, attractiveness, and health
of faces.
Elliot and Maier (2012) have proposed color-in-context the-
ory, which draws on social learning, as well as biology. Some
responses to color stimuli are presumed to be solely due to the
repeated pairing of color and particular concepts, messages, and
experiences. Others, however, are presumed to represent a bio-
logically engrained predisposition that is reinforced and shaped
by social learning. Through this social learning, color associ-
ations can be extended beyond natural bodily processes (e.g.,
blood flow modulations) to objects in close proximity to the body
(e.g., clothes, accessories). Thus, for example, red may not only
increase attractiveness evaluations when viewed on the face, but
also when viewed on a shirt or dress. As implied by the name of
the theory, the physical and psychological context in which color
is perceived is thought to influence its meaning and, accordingly,
responses to it. Thus, blue on a ribbon is positive (indicating first
place), but blue on a piece of meat is negative (indicating rot-
ten), and a red shirt may enhance the attractiveness of a potential
mate (red =sex/romance), but not of a person evaluating one’s
competence (red =failure/danger).
Meier and Robinson (2005)andMeier (in press)haveposited
a conceptual metaphor theory of color. From this perspective,
people talk and think about abstract concepts in concrete terms
grounded in perceptual experience (i.e., they use metaphors) to
help them understand and navigate their social world (Lako
and Johnson, 1999). Thus, anger entails reddening of the face,
so anger is metaphorically described as “seeing red,” and pos-
itive emotions and experiences are often depicted in terms of
lightness (rather than darkness), so lightness is metaphorically
linked to good (“seeing the light”) rather than bad (“in the dark”).
These metaphoric associations are presumed to have implications
for important outcomes such as morality judgments (e.g., white
things are viewed as pure) and stereotyping (e.g., dark faces are
viewed more negatively).
For many years it has been known that light directly influ-
ences physiology and increases arousal (see Cajochen, 2007,for
a review), but recently theorists have posited that such effects
are wavelength dependent. Blue light, in particular, is posited
to activate the melanopsin photoreceptor system which, in turn,
activates the brain structures involved in sub-cortical arousal
and higher-order attentional processing (Cajochen et al., 2005;
Lockley et al., 2006). As such, exposure to blue light is expected to
facilitate alertness and enhance performance on tasks requiring
sustained attention.
Evaluation and Recommendations
Drawing on recent theorizing in evolutionary psychology,
emotion science, retinal physiology, person perception, and
social cognition, the aforementioned conceptualizations repre-
sent important advances to the literature on color and psycho-
logical functioning. Nevertheless, theory in this area remains at a
nascent level of development, and the following weaknesses may
be identified.
First, the focus of theoretical work in this area is either
extremely specific or extremely general. A precise conceptual
proposition such as red signals dominance and leads to compet-
itive advantage in sports (Hill and Barton, 2005)isvaluablein
that it can be directly translated into a clear, testable hypothe-
sis; however, it is not clear how this specific hypothesis connects
to a broader understanding of color–performance relations in
achievement settings more generally. On the other end of the
spectrum, a general conceptualization such as color-in-context
theory (Elliot and Maier, 2012)isvaluableinthatitoerssev-
eral widely applicable premises; however, these premises are
only vaguely suggestive of precise hypotheses in specific con-
texts. What is needed are mid-level theoretical frameworks that
comprehensively, yet precisely explain and predict links between
color and psychological functioning in specific contexts (for
emerging developments, see Pazda and Greitemeyer, in press;
Spence, in press;Stephen and Perrett, in press).
Second, the extant theoretical work is limited in scope in
terms of range of hues, range of color properties, and direction
of influence. Most theorizing has focused on one hue, red, which
is understandable given its prominence in nature, on the body,
and in society (Changizi, 2009;Elliot and Maier, 2014); however,
Frontiers in Psychology | www.frontiersin.org 2April 2015 | Volume 6 | Article 368
Elliot Color and psychological functioning
other hues also carry important associations that undoubtedly
have downstream effects (e.g., blue: Labrecque and Milne, 2012;
green: Akers et al., 2012). Color has three basic properties: hue,
lightness, and chroma (Fairchild, 2013).Variationinanyorall
of these properties could influence downstream affect, cogni-
tion, or behavior, yet only hue is considered in most theorizing
(most likely because experientially, it is the most salient color
property). Lightness and chroma also undoubtedly have impli-
cations for psychological functioning (e.g., lightness: Kareklas
et al., 2014; chroma: Lee et al., 2013); lightness has received
some attention within conceptual metaphor theory (Meier, in
press;seealsoPrado-León and Rosales-Cinco, 2011), but chroma
has been almost entirely overlooked, as has the issue of combi-
nations of hue, lightness, and chroma. Finally, most theorizing
has focused on color as an independent variable rather than a
dependent variable; however, it is also likely that many situa-
tional and intrapersonal factors influence color perception (e.g.,
situational: Bubl et al., 2009; intrapersonal: Fetterman et al.,
2015).
Third, theorizing to date has focused primarily on main
effects, with only a modicum of attention allocated to the impor-
tant issue of moderation. As research literatures develop and
mature, they progress from a sole focus on “is” questions (“Does
X influence Y?”) to additionally considering when” questions
(“Under what conditions does X influence Y and under what
conditions does X not influence Y?”). These “second generation”
questions (Zanna and Fazio, 1982, p. 283) can seem less excit-
ing and even deflating in that they posit boundary conditions
that constrain the generalizability of an effect. Nevertheless, this
step is invaluable in that it adds conceptual precision and clar-
ity, and begins to address the issue of real-world applicability. All
color effects undoubtedly depend on certain conditions culture,
gender, age, type of task, variant of color, etc. and acquiring
an understanding of these conditions will represent an impor-
tant marker of maturity for this literature (for movement in this
direction, see Schwarz and Singer, 2013;Tracy and Beall, 2014;
Bertrams et al., 2015;Buechner et al., in press;Young, in press).
Another, more succinct, way to state this third weakness is that
theorizing in this area needs to take context, in all its forms, more
seriously.
Empirical Work
Background and Recent Developments
Empirical work on color and psychological functioning dates
back to the late 19th century (Féré, 1887;seePressey, 1921,
for a review). A consistent feature of this work, from its incep-
tion to the past decade, is that it has been fraught with major
methodological problems that have precluded rigorous testing
and clear interpretation (O’Connor, 2011). One problem has
been a failure to attend to rudimentary scientific procedures
such as experimenter blindness to condition, identifying, and
excluding color deficient participants, and standardizing the
duration of color presentation or exposure. Another problem
has been a failure to specify and control for color at the spec-
tral level in manipulations. Without such specification, it is
impossible to know what precise combination of color proper-
ties was investigated, and without such control, the confounding
of focal and non-focal color properties is inevitable (Whitfield
and Wiltshire, 1990;Valdez and Mehrabian, 1994). Yet another
problem has been the use of underpowered samples. This prob-
lem, shared across scientific disciplines (Maxwell, 2004), can
lead to Type I errors, Type II errors, and inflated effect sizes
(Fraley and Vazire, 2014;Murayama et al., 2014). Together, these
methodological problems have greatly hampered progress in this
area.
Although some of the aforementioned problems remain (see
“Evaluation and Recommendations” below), others have been
rectified in recent work. This, coupled with advances in theory
development, has led to a surge in empirical activity. In the fol-
lowing, I review the diverse areas in which color work has been
conducted in the past decade, and the findings that have emerged.
Space considerations require me to constrain this review to a
brief mention of central findings within each area. I focus on
findings with humans (for reviews of research with non-human
animals, see Higham and Winters, in press;Setchell, in press)that
have been obtained in multiple (at least five) independent labs.
Tab l e 1 provides a summary, as well as representative examples
and specific references.
In research on color and selective attention, red stimuli have
been shown to receive an attentional advantage (see Folk, in
press, for a review). Research on color and alertness has shown
that blue light increases subjective alertness and performance on
attention-based tasks (see Chellappa et al., 2011,forareview).
Studies on color and athletic performance have linked wearing
red to better performance and perceived performance in sport
competitions and tasks (see Maier et al., in press,forareview).
In research on color and intellectual performance, viewing red
prior to a challenging cognitive task has been shown to under-
mine performance (see Shi et al., 2015, for a review). Research
focused on color and aggressiveness/dominance evaluation has
shown that viewing red on self or other increases appraisals of
aggressiveness and dominance (see Krenn, 2014,forareview).
Empirical work on color and avoidance motivation has linked
viewing red in achievement contexts to increased caution and
avoidance (see Elliot and Maier, 2014,forareview).Inresearch
on color and attraction, viewing red on or near a female has been
shown to enhance attraction in heterosexual males (see Pazda
and Greitemeyer, in press, for a review). Research on color and
store/company evaluation has shown that blue on stores/logos
increases quality and trustworthiness appraisals (see Labrecque
and Milne, 2012, for a review). Finally, empirical work on color
and eating/drinking has shown that red influences food and bev-
erage perception and consumption (see Spence, in press,fora
review).
Evaluation and Recommendations
The aforementioned findings represent important contributions
to the literature on color and psychological functioning, and
highlight the multidisciplinary nature of research in this area.
Nevertheless, much like the extant theoretical work, the extant
empirical work remains at a nascent level of development, due, in
part, to the following weaknesses.

Elliot Color and psychological functioning
First, although in some research in this area color proper-
ties are controlled for at the spectral level, in most research it
(still) is not. Color control is typically done improperly at the
device (rather than the spectral) level, is impossible to imple-
ment (e.g., in web-based platform studies), or is ignored alto-
gether. Color control is admittedly difficult, as it requires tech-
nical equipment for color assessment and presentation, as well
as the expertise to use it. Nevertheless, careful color control is
essential if systematic scientific work is to be conducted in this
area. Findings from uncontrolled research can be informative in
initial explorations of color hypotheses, but such work is inher-
ently fraught with interpretational ambiguity (Whitfield and
Wiltshire, 1990;Elliot and Maier, 2014)thatmustbesubsequently
addressed.
Second, color perception is not only a function of lightness,
chroma, and hue, but also of factors such as viewing distance
and angle, amount and type of ambient light, and presence of
other colors in the immediate background and general envi-
ronmental surround (Hunt and Pointer, 2011;Brainard and
Radonji´
c, 2014;Fairchild, 2015). In basic color science research
(e.g., on color physics, color physiology, color appearance mod-
eling, etcetera; see Gegenfurtner and Ennis, in press;Johnson,
in press;Stockman and Brainard, in press), these factors are
carefully specified and controlled for in order to establish stan-
dardized participant viewing conditions. These factors have been
largely ignored and allowed to vary in research on color and psy-
chological functioning, with unknown consequences. An impor-
tant next step for research in this area is to move to incor-
porate these more rigorous standardization procedures widely
utilized by basic color scientists. With regard to both this and the
aforementioned weakness, it should be acknowledged that exact
and complete control is not actually possible in color research,
given the multitude of factors that influence color perception
(Committee on Colorimetry of the Optical Society of America,
1953) and our current level of knowledge about and ability to
control them (Fairchild, 2015). As such, the standard that must
be embraced and used as a guideline in this work is to control
color properties and viewing conditions to the extent possible
given current technology, and to keep up with advances in the
field that will increasingly afford more precise and efficient color
management.
Third, although in some research in this area, large, fully
powered samples are used, much of the research remains
underpowered. This is a problem in general, but it is partic-
ularly a problem when the initial demonstration of an effect
is underpowered (e.g., Elliot and Niesta, 2008), because ini-
tial work is often used as a guide for determining sample size
in subsequent work (both heuristically and via power analy-
sis). Underpowered samples commonly produce overestimated
effect size estimates (Ioannidis, 2008), and basing subsequent
sample sizes on such estimates simply perpetuates the prob-
lem. Small sample sizes can also lead researchers to prema-
turely conclude that a hypothesis is disconfirmed, overlooking a
potentially important advance (Murayama et al., 2014). Findings
from small sampled studies should be considered preliminary;
running large sampled studies with carefully controlled color
stimuli is essential if a robust scientific literature is to be devel-
oped. Furthermore, as the “evidentiary value movement” (Finkel
et al., 2015) makes inroads in the empirical sciences, color
scientists would do well to be at the leading edge of imple-
menting such rigorous practices as publically archiving research
materials and data, designating exploratory from confirmatory
analyses, supplementing or even replacing significant testing
with “new statistics” (Cumming, 2014), and even preregistering
research protocols and analyses (see Finkel et al., 2015,foran
overview).
Conclusion
In both reviewing advances in and identifying weaknesses of the
literature on color and psychological functioning, it is impor-
tant to bear in mind that the existing theoretical and empirical
work is at an early stage of development. It is premature to offer
any bold theoretical statements, definitive empirical pronounce-
ments, or impassioned calls for application; rather, it is best to
be patient and to humbly acknowledge that color psychology is a
uniquely complex area of inquiry (Kuehni, 2012;Fairchild, 2013)
that is only beginning to come into its own. Findings from color
research can be provocative and media friendly, and the pub-
lic (and the field as well) can be tempted to reach conclusions
before the science is fully in place. There is considerable promise
in research on color and psychological functioning, but consider-
ably more theoretical and empirical work needs to be done before
the full extent of this promise can be discerned and, hopefully,
fulfilled.

The present study of mixed approach and quasi-experimental technique, had the general purpose of evaluating the effects of color on creative capacity and on creative products made by students of Architecture and Design of the Autonomous University of Baja California (UABC), in a virtual learning environment (VLE) designed in green and gray interfaces. As specific objectives, it was sought to establish the possible relationships generated between the demographic and emotional characteristics of the student, how color influenced the creativity shown in a tangible way in a creative product, a story, different uses of an object and a drawing; all carried out in a virtual context. According to the above, a total of 242 tests were applied, forming two groups: the control group with 121 applications in gray and the experimental group with 121 applications in green. The sample consisted of second semester Architecture and Design students from the three UABC campuses. Within the method, three instruments were applied: the ICBT (Ishihara Color Blind Test), which allowed ruling out color blindness; then the EVEA (Mood State Assessment Scale) was applied, used to measure the transitory state of mind from a psychological perspective; subsequently, the EMUC test (Multifactorial Evaluation of Creativity), a test battery that allowed evaluating verbal, applied and visuomotor creativity; next, a workshop class was simulated in which the students made a creative product. Finally, they were asked some questions regarding their mood and color perception. The results showed that the color green influenced the mood of the students, with joy being the highest average. The general average of creativity was higher in the gray test than in the green one. However, in particular, the visuomotor creativity and creative product scores were higher in the green test. On the other hand, in the gray test, the highest average was obtained in verbal creativity, applied creativity. In addition, in both tests, women had higher scores than men in creativity; especially in the visuomotor and creative product, where they integrated more aesthetic details. Regarding the average of the faculties, the Ensenada campus was higher, followed by the Mexicali campus, and finally the Tijuana campus; allowing to identify that both the environment, climate, geographical location among other psycho-social factors can influence creative performance within a VLE.

This study aims to identify factors that influence visitors' perceptions of color selection and interior design elements in coffee shops and their impact on non-verbal communication experiences and social interaction. A quantitative approach was employed, involving 135 randomly selected respondents, who were then analyzed through Exploratory Factor Analysis (EFA) to categorize variables related to visitors' perceptions of interior design. The instrument used was a questionnaire with a Likert scale, covering dimensions of comfort, visual appeal, social warmth, and spatial flexibility for activities. The analysis results reveal three main factors affecting visitors' non-verbal communication experience. The first factor, Individual and Visual Comfort, includes variables such as theme suitability, aesthetics, and lighting, with an eigenvalue of 1.691, explaining 24.16% of the variance. The second factor, Familiarity and Emotional Attachment, encompasses social warmth and spatial tranquility, with an eigenvalue of 1.476, accounting for 21.09% of the variance. The third factor, Flexibility and Social Activity, relates to spaces that support social engagement and productivity, with an eigenvalue of 1.129, explaining 16.13% of the variance. Together, these three factors account for 61.38% of the variance in visitor perception.

... The positive emotions elicited by the red brick environment were relatively weaker than those generated by the other environments, with an FAA value of 2.63 µV. According to Elliot and Maier [84], red is often associated with anxiety and agitation, which can influence emotional experiences during learning. Thus, the red hue of the bricks could affect emotional responses in a learning context, leading to a lower FAA increase compared with the responses elicited by other material environments. ...

The influence of building materials on the physical aspects of educational spaces is significant, shaping both functionality and aesthetic appeal while directly affecting the emotional and cognitive states of students. Despite its significance, this area has not been extensively explored. This study investigated the effects of the visual perception of architectural materials on emotional states and cognitive functions in learning environments. Four materials, namely, red brick, concrete, wood, and white paint, were selected for a material substitution experiment conducted via VR simulations with 46 participants. To assess these effects, eye movement data and bioelectrical responses were methodically recorded, along with the participants’ self-reported emotional states through structured questionnaires. The results indicated that settings featuring wood and red bricks significantly enhanced emotional states, fostering relaxation and positive experiences that contributed to increased creativity. Conversely, settings with concrete and white paint improved cognitive functioning and promoted emotional stability and rational thinking, which enhanced focus and educational efficiency. These findings suggest the impact of visual perception of building materials on emotional and cognitive states, emphasizing the importance of material selection in creating learning spaces that balance cognitive demands with emotional activation. This study provides valuable insights for designing conducive physical learning environments and exploring the psychological and physiological effects of architectural materials.

The interplay between background colour and individual characteristics such as gender significantly influences cognitive performance in visual attention tasks. While colour's role in cognition has been studied, the impact of low-saturation colours and their gender-specific interactions remains underexplored. This study examined the effects of nine background colours-seven low-saturation hues (red, orange, yellow, green, cyan, blue, purple), standard grey, and standard white-on visual attention among 54 participants (27 males, 27 females) in a dark psychophysical laboratory. A multimodal approach combined cognitive performance data (accuracy and search time), functional near-infrared spectroscopy (fNIRS) data (activation of brain regions associated with visual attention), and eye-tracking measures (fixation and pupil metrics). Results revealed that males exhibited higher accuracy and faster search times on cyan and yellow backgrounds, whereas females demonstrated greater neural activation on orange and cyan backgrounds. Eye-tracking data indicated longer fixation durations for females on orange backgrounds and higher cognitive load for males on blue backgrounds. Correlation analysis revealed contrasting cognitive strategies, females showed a positive correlation between search time and accuracy, while males exhibited a negative correlation. These findings underscore the nuanced role of gender-specific responses to background colour in shaping visual cognition. Insights gained have applications in human-computer interaction, educational tools, and tailored interventions for cognitive impairments. Introduction In today's rapidly evolving information technology landscape, cognitive abilities are increasingly significant in learning, work, and daily life [1-3]. Data from the World Health Organization (WHO) indicate that 1 billion people-approximately 15% of the global population-are affected by varying degrees of mental or cognitive disorders [4-6]. These challenges not only impact individual quality of life and work efficiency but may also have profound effects on socioeconomic development [7-9]. Enhancing individual cognitive performance becomes particularly crucial. Among cognitive functions, Visual Attention (VA) is vital for information selection and processing, forming the foundation for learning, decision-making, and problem-solving [10-13]. Understanding the factors influencing visual attention performance is therefore crucial for enhancing cognitive efficiency and developing effective intervention strategies. Colour, as a significant characteristic of visual stimuli, profoundly influence individuals' allocation and concentration of attention [14-16]. Existing studies have demonstrated that colour affects emotions, psychological states, and cognitive processes, enabling improved attention concentration and interaction with information systems [15, 17-20]. Despite this, previous research has focused on highly saturated or three primary colours, with limited analysis of low-saturation backgrounds [21-23]. Furthermore, evidence suggests that males and females may exhibit distinct attention allocation strategies [24-27], yet the interaction between gender and background colour in visual cognition remains underexplored. Additionally, previous studies have typically used a single method (e.g. behavioural data or self-report data) to assess cognitive performance [28-30], which ignores the relationship between brain activities performance and cognitive responses. On the other hand, the functional near-infrared spectroscopy (fNIRS) monitors cerebral blood flow changes in real time, which shows the ability to understanding the activation of brain regions associated with VA [31-33]. Meanwhile, Eye-tracking technology provides quantitative analysis of visual attention allocation and decision-making processes [34-35]. Therefore, this study investigates how nine background colours, including seven low-saturation hues (red, orange, yellow, green, cyan, blue, purple) and two achromatic colours (grey and white), influence visual attention. By combining cognitive performance data (accuracy and search time), fNIRS-based brain activation data, and eye-tracking metrics (fixation duration and pupil diameter), this research addresses the following objectives: 1. Examine cognitive performance differences in visual attention performance across genders under varying background colours. 2. Explore patterns of brain activation associated with visual attention tasks using fNIRS data, with an emphasis on gender-specific differences. 3. Correlating accuracy and search time integrates cognitive performance data to uncover potential cognitive strategies. Method Colour conditions To investigate the influence of background colours on visual attention, this study employed nine background colours within the CIELAB colour space. These included seven low-saturation hues (red, orange, yellow, green, cyan, blue, purple) and two achromatic colours (grey and white). By focusing on low-saturation colours, this study aims to explore nuanced behavioural and physiological patterns across genders in visual attention tasks. All colours, except white, were standardised to maintain consistent luminance, ensuring that luminance contrast effects were controlled. Grey characters were displayed against the white background, while white characters were presented on all other coloured backgrounds. Lightness (L*) and chromaticity (a*, b*) values were measured in a display by using a JETI specbos 1211 UV-2

This study analyzed the relationship between colors and various aspects of the work environment, such as emotions, health and productivity. The review of recent scientific articles showed that colors have a significant impact on workers, and can positively or negatively influence their well-being and performance. Warm colors, such as red, stimulate energy but can cause irritability, while cool colors, such as blue, promote calm and concentration. The research also highlighted the importance of combining colors with natural elements and of workers' participation in choosing the colors of the environment. The review concluded that the appropriate choice of colors can optimize the work environment, increasing employee satisfaction and productivity. However, the research identified the need for further studies to deepen the understanding of the complexity of the relationship between colors and human behavior in the work context.

الألوان هي جزء من عالمنا ولا قيمة لما نراه دونها، ولهذا كان الغرض من هذا البحث الإجابة على التساؤل الذي يسعى إلى التحقيق في التأثير السيكولوجي والفسيولوجي للون ملابس المرضى على المرضى المقيمين في بيئات الرعاية الصحية. وقد اتبعت الدراسة منهج المراجعة المنهجية Systematic Review للتحقق من مدى تأثير ألوان ملابس المرضى في بيئات الرعاية الصحية. ولقد تم تطبيق إجراءات متسلسلة لتحقيق هدف الدراسة ابتداء بصياغة تساؤل الدراسة الرئيسي وصولاً إلى وضع معايير لاختيار وإدراج واستبعاد الدراسات السابقة وانتهاء إلى الخروج بالنتائج ومناقشتها. وإجمالا، أكدت النتائج على وجود علاقة قوية بين اللون وبين البيئة المحيطة بالإنسان، فاللون ليس مجرد إضافة جمالية لملابس المريض فحسب، بل هو أداة أثّرت على مزاجية ونفسية المريض بشكل إيجابي وفعال وانعكس تأثيره على سلوكياته وعلى تواصله مع البيئة المحيطة. وبالتالي فإن نتائج الدراسة الحالية أثبتت أهمية العناية باختيار اللون داخل بيئات الرعاية الصحية، لا سيما في ملابس المرضى لما له من قدرة تأثيرية على تحفيز الاستجابات المتعلقة باللاوعي لدى المريض سواء كانت بطريقة إيجابية أو سلبية. Colors are an integral part of our world, and what we see would be meaningless without them. Therefore, the purpose of this research is to address the question investigating the psychological and physiological impact of patient clothing colors on inpatients in healthcare environments. The study adopted the **Systematic Review** methodology to examine the extent to which patient clothing colors influence healthcare settings. A series of structured procedures were implemented to achieve the study’s objective, beginning with the formulation of the main research question, followed by establishing criteria for selecting, including, and excluding previous studies, and concluding with deriving and discussing the findings. Overall, the results confirmed a strong relationship between color and the surrounding environment. Color is not merely an aesthetic addition to patient attire but a tool that significantly and positively influences patients’ moods and psychological states, which, in turn, affects their behavior and interactions with their surroundings. Consequently, the findings of this study highlight the importance of carefully selecting colors within healthcare settings, particularly in patient clothing, due to its profound impact on triggering subconscious responses—whether positive or negative.

Emotion recognition is critical for various applications such as early detection of mental health disorders and emotion based smart home systems. Previous studies used various sensing methods for emotion recognition, such as wearable sensors, cameras, and microphones. However, these methods have limitations in long term domestic, including intrusiveness and privacy concerns. To overcome these limitations, this paper introduces a nonintrusive and privacy friendly personalized emotion recognition system, EmotionVibe, which leverages footstep induced floor vibrations for emotion recognition. The main idea of EmotionVibe is that individuals' emotional states influence their gait patterns, subsequently affecting the floor vibrations induced by their footsteps. However, there are two main research challenges: 1) the complex and indirect relationship between human emotions and footstep induced floor vibrations and 2) the large between person variations within the relationship between emotions and gait patterns. To address these challenges, we first empirically characterize this complex relationship and develop an emotion sensitive feature set including gait related and vibration related features from footstep induced floor vibrations. Furthermore, we personalize the emotion recognition system for each user by calculating gait similarities between the target person (i.e., the person whose emotions we aim to recognize) and those in the training dataset and assigning greater weights to training people with similar gait patterns in the loss function. We evaluated our system in a real-world walking experiment with 20 participants, summing up to 37,001 footstep samples. EmotionVibe achieved the mean absolute error (MAE) of 1.11 and 1.07 for valence and arousal score estimations, respectively, reflecting 19.0% and 25.7% error reduction compared to the baseline method.

The Roerich family is a remarkable phenomenon in the cultural history of Russia and India of the 20 th century. Nicholas Roerich was a great artist, thinker, traveller, and the founder of the international Agreement on the Protection of Artistic and Scientific Institutions and Historical Monuments signed by the 22 countries of Northern and Southern Americas in 1935. Helena Roerich was a unique philosopher of cosmism who contributed to the creation of Living Ethics philosophical system. Elder son George was a well-known Orientalist, and younger brother Svetoslav was an artist and an art theorist. The art of this family a shared heritage of Russia and India. Although the artistic legacy of the Roerichs has been investigated from a variety of angles for the past almost one hundred years of Roerichology, it is rather surprising that the question of the philosophy of colour has been neglected. In the given article the question of the philosophy of colour will be considered primarily from the point of view of Living Ethics as well as from the point of view of the literary legacy of Nicholas and Svetoslav Roerichs. And, of course, we take into account the paintings of the Roerichs, both the father and the son, as their paintings speak for themselves.

In this study, a virtual environment was created to investigate the effect of color saturation on walking speed and gaze behavior. Participants walked along a pathway with different sidewall color patterns, each with varying levels of saturation (non-colored, low, medium, high). Results showed walking speed was faster under conditions with medium to high saturation compared to non-colored and low saturation. Additionally, gaze analysis revealed participants tended to look more at the sidewalls when medium to high saturation colors were used.

This study examined the proposition that competing against red-clad opponents hinders the performance of soccer (football) athletes. 40 experienced players took 10 penalty kicks against a goalkeeper wearing a black jersey and, 1 week later, took 10 penalty kicks against a goalkeeper wearing either a red, green, blue, or yellow jersey. Prior to each set of kicks, participants reported their expectancy of success. Players facing red-clad goalkeepers scored on fewer penalty kicks than those facing either blue- or green-clad goalkeepers, but no differences in expectancy of success emerged. The findings indicate that athletes wearing red may have an advantage over their opponents.

Fehrman and Ferhman (2001), mention that blue is associated with tranquility, security, comfort, depression, melancholy, relaxation, isolation, infinitude and cold. However, these data do not indicate specifications for saturation and lightness of the hue in question. Is it a dark blue of low saturation or a very saturated light blue? Which type of blue actually evokes the stated meanings? Basing itself on such questions, a cross-sectional paper and pencil survey (of nine colors in three different intensities and lightnesses) was conducted with 622 subjects. The results showed different meanings associated with the same hue when there were variations in lightness and saturation. All of the foregoing results indicate the importance of continued research into the attributes that cause a color's associated meanings to vary. Knowing how (and perhaps why) these meanings vary with saturation and lightness should enable color to be used more effectively in all kinds of design applications.

An online, hypothetical, tipping-scenario experiment found that subjects tipped the servers less (not more) when those servers wore a red shirt than when they wore a white or black one and that female subjects perceived a waiter (but not a waitress) as less attractive when wearing a red shirt than when wearing a white or black shirt. These findings are opposite those in the existing literature and suggest that the earlier findings are less generalizable than previously believed and that the process underlying previous clothing color effects on tipping may not be precisely what the researchers thought it was. Possible explanations of the discrepant findings are discussed along with directions for future research and practical implications.
