Article
Full-text available
We undertook psychophysical experiments to determine whether the color of the after-image produced by viewing a colored patch which is part of a complex multi-colored scene depends on the wavelength-energy composition of the light reflected from that patch. Our results show that it does not. The after-image, just like the color itself, depends on t...
Article
A range of explanations have been advanced for the systems of colour names found in different languages. Some explanations give special, fundamental status to a subset of colour categories. We argue that a subset of colour categories, if fundamental, will be coherent - meaning that a non-trivial criterion distinguishes them from the other colour ca...
Conference Paper
Full-text available
We explore synonyms in colour naming within and across three languages, British English, Estonian and Greek, using data collected from a crowdsourcing experiment. We identified 30 common lexical colour categories in British English, 41 in Estonian and 29 in Greek, where no one category was fully contained within others. The synonymy analysis within...

Languages differ markedly in the number of colour terms in their lexicons. The Himba, for example, a remote culture in Namibia, were reported in 2005 to have only a 5-colour term language. We re-examined their colour naming using a novel computer-based method drawing colours from across the gamut rather than only from the saturated shell of colour...
Article
Full-text available
The present study is an apparent-time analysis of color terms in Russian native speakers ( N = 1927), whose age varied between 16 and 98 years. Stratified sampling was employed with the following age groups: 16–19, 20–29, and so on, with the oldest group of 70 years and over. Color names were elicited in a web-based psycholinguistic experiment ( ht...
Conference Paper
Full-text available
In the present study, we investigated age-related differences in richness and diversity of color lexicon in Russian native speakers. Color names were elicited in 2018-2020 in an ongoing web-based psycholinguistic experiment (https://colournaming.com). An unconstrained color-naming method was employed. A final dataset contained responses of 1,967 na...
Chapter
Crowdsourcing of multilingual color names refers to distributed experimental methodologies designed to collect large datasets of color naming responses in different languages from a large number of observers over the Internet.
Poster
Full-text available
Online colour naming experiments are often criticised for the uncalibrated colour reproduction of different displays and the uncontrolled viewing environment. In contrast, laboratory-based (offline) experiments are criticised for not reproducing “real-world” monitor settings. In this study, we compare the performance of online and offline colour na...
Thesis
Full-text available
For computational methods aiming to reproduce colour names that are meaningful to speakers of different languages, the mapping between perceptual and linguistic aspects of colour is a problem of central information processing. This thesis advances the field of computational colour communication within different languages in five main directions. Fi...
Conference Paper
Full-text available
The present study is an age-group analysis of Russian colour terms (CTs) derived from names of food objects and edible substances. CTs were elicited in a web-based experiment using an unconstrained colour-naming method. Respondents, native Russian speakers (N = 2,457), were aged between 16-95 years. In the analysis, data were stratified for seven a...
Article
Full-text available
We used the Land Colour Mondrian experiments in a Bayesian context to test the degree to which subjects vary in categorizing the colour of different patches, when each patch is made to reflect light of the identical wavelength‐energy composition. The brain uses a ratio‐taking mechanism to determine the ratio of light of every waveband reflected fro...
Conference Paper
Full-text available
The recent establishment of the physiologically-based colour matching functions (CIE 170-1:2006) provides a good determination of the cone excitation space but its relationship to higher-order mechanisms of colour appearance remains elusive. In this study, we determined the location of colour names within LMS space (Stockman & Sharpe, 2000) through...
Article
Full-text available
Ordinary language users group colours into categories that they refer to by a name e.g. pale green. Data on the colour categories of English speakers was collected using online crowd sourcing – 1,000 subjects produced 20,000 unconstrained names for 600 colour stimuli. From this data, using the framework of Information Geometry, a Riemannian metric...

Full-text available
In the work reported here, we used the Land Color Mondrian experiments to test the degree to which subjects vary in their perception of color categories. Twenty subjects of different ethnic and cultural backgrounds, for all but one of whom English was not the primary language, viewed 8 patches of different color in two Mondrian displays; each patch...

Colour naming links vision and speech. In a cognitive model the colour in an external stimulus is encoded as a visual percept, which is matched against a store of colour percepts in long-term memory. The result is an index enabling a word or phrase to be retrieved from a colour lexicon. The colour name is a category label for a region of colour spa...
Article
Full-text available
The present study is an extension of our analysis of Russian basic color terms (BCTs) elicited in a web‐based psycholinguistic experiment. Color samples (N = 600) were approximately uniformly distributed in the Munsell color solid. An unconstrained color‐naming method was employed. Native Russian speakers (N = 713; 333 males) participated in the st...
Chapter
Full-text available
Previous research in colour naming has been mostly focused on a small number of basic colour categories rather than towards the development of more subtle colour identifications. This has led to a preponderance of ‘basic’ colour schemes and has limited the visualisation of complex data. In this chapter, we present the findings of a long-running Int...

Russian color naming was explored in a web-based experiment. The purpose was 3-fold: to examine (1) CIELAB coordinates of centroids for 12 Russian basic color terms (BCTs), including 2 Russian terms for “blue”, sinij “dark blue”, and goluboj “light blue”, and compare these with coordinates for the 11 English BCTs obtained in earlier studies; (2) fr...

In the present study we explored Russian colour naming in a web-based psycholinguistic experiment (http://www.colournaming.com). Colour singletons representing the Munsell Color Solid (N=600 in total) were presented on a computer monitor and named using an unconstrained colour-naming method. Respondents were Russian speakers (N=713). For gender-spl...

We undertook psychophysical experiments to determine whether the color of the after-image produced by viewing a colored patch which is part of a complex multi-colored scene depends on the wavelength-energy composition of the light reflected from that patch. Our results show that, just as the color of a patch which is part of a complex scene is inde...

This study explores the use of English colour names in large datasets from informal Twitter messages and the well-structured corpus of Google Books. Because colour names in text have no directly associated chromatic stimuli, the corresponding colour categories of colour words was assessed from responses in an online colour naming experiment. A comp...

Full-text available
In an unconstrained colour naming experiment conducted over the web, 330 participants named 600 colour samples in English. The 30 most frequent monolexemic colour terms were analyzed with regards to frequency, consensus among genders, response times, consistency of use, denotative volume in the Munsell and OSA colour spaces and inter-experimental a...

Article
Data is presented on the colour and spectral reflectances of stool samples from healthy young infants (mean age 6 days). The range of spectral reflectances is well described by a pigment mixture model with three components—a pale component corresponding to partially digested milk fats, a yellow component corresponding to bilirubin breakdown product...

Colour specification is not only the domain of technologists but is also an important process for anyone who needs to communicate about colour in the multilingual Internet environment. We have developed an online application Colournamer, a synthetic observer ‘trained’ by the participants’ responses, to facilitate colour communication between differ...

Gender differences in colour naming were explored using a web-based experiment in English. Each participant named twenty colours selected from 600 Munsell samples, presented one at a time against a neutral background. Colour names and typing onset response times were registered. For the eleven basic colour terms, elicitation frequency was comparabl...

Full-text available
Unique hue settings of 185 observers under three room-lighting conditions were used to evaluate the accuracy of full and mixed chromatic adaptation transform models of CIECAM02 in terms of unique hue reproduction. Perceptual hue shifts in CIECAM02 were evaluated for both models with no clear difference using the current Commission Inter-nationale d...
Chapter
Full-text available
Existing research in colour naming has been mostly focused on a small number of basic colour categories rather than towards the development of more subtle colour identifications. This often leads to an over-saturation in the use of 'basic' colour schemes and can limit the differentiation of new ideas. In this chapter, we present the findings of a f...
Article
Full-text available
Observers are faster to detect a target among a set of distracters if the targets and distracters come from different color categories. This cross-boundary advantage seems to be limited to the right visual field, which is consistent with the dominance of the left hemisphere for language processing [Gilbert et al., Proc. Natl. Acad. Sci. USA 103, 48...
Conference Paper
Full-text available
Extensive research in colour naming has been more focused on a small number of consensual colour categories than towards the development of more subtle colour identifications (Gage 1993, Berlin & Kay 1969) but how can we communicate "basic" and more "delicate" colour names within and between different cultures in an agreeable way? This workshop int...
Article
Full-text available
Unique hue settings of 185 observers under two room lighting conditions were used to evaluate the accuracy of mixed chromatic adaptation transform models of CIECAM02 in terms of unique hue reproduction. The current CIE recommendation for mixed chromatic adaptation ratio produced unsatisfying performance in terms of perceptual hue shifts in CIECAM02...
