DEVELOPMENT OF PIGMENTS AND COLOR USE IN PREHISTORIC TIMES
Traditionally it is assumed, that the observed diversity of pigments in prehistoric times depended on our ancestors’ knowledge on locating sources of raw materials. The application of basic colours very often was associated only with certain ritual activities, simple life style and limited basic needs. Probably it could be attributed to particular prehistoric cultures and to a limited period of time. Our study demonstrates that the general trend is related to the evolution of colour vision and possibilities of humans to distinguish the variety of pigmentation. These are not simple skills or the gifts of nature. By the development of abstract thinking, the demand for diversity of colours rose rapidly and simple colour tones were supplemented with different shades, various intensities, the images became polychromatic and multilayered. Before commencing the painting, the surface was evened and background colour layer was applied. The paintings were made applying different pigments. In this context the necessity to locate raw material sources for variable pigments or to process them artificially is likely a consequence of the necessity for particular result rather than a simple motivation.
