He found that mnoogobrazie color, open the ancient Greeks and Romans, may be limited. Da Vinci wrote: "Simple colors - 6: white, yellow, green, blue, red and black. " Leonardo da Vinci also identified two possible dimensions of colors: the artistic and physical. Color - one of the properties of material objects, conceived as a conscious visual sensation. One or different color 'is assigned to' man-made objects in their visual perception. Color perception may partially vary depending on the psychophysiological state of the observer, such as increase in hazardous situations, decrease in fatigue.
In most cases, the color sensation is the result of exposure to the eye flow of electromagnetic radiation of wavelengths in which the radiation perceived by the eye (visible range - a wavelength from 380 to 760 nm). Sometimes the color sensation occurs without the influence of radiant flux on the eyes - at the pressure on the eyeball, stroke, electrical stimulation, etc., as well as mental associations with the other senses - sound, heat, etc., and as a result of the imagination. Different color sensations cause differently colored objects, their raznoosveschennye sites, as well as light sources and produced by them lighting. In this case, the perception of colors may vary (even with the same relative spectral composition of radiation fluxes), depending on whether it falls into the eye radiation from light sources or from objects. In human terms, however, used the same terms to refer to the color of these two different types of objects.
