color (redirected from confusion colors)

color /col·or/ (kul´er)

1. a property of a surface or substance due to absorption of certain light rays and reflection of others within the range of wavelengths (roughly 370–760 mµ) adequate to excite the retinal receptors.

2. radiant energy within the range of adequate chromatic stimuli of the retina, i.e., between the infrared and ultraviolet.

3. a sensory impression of one of the rainbow hues.

complementary colors  a pair of colors the sensory mechanisms for which are so linked that when they are mixed on the color wheel they cancel each other out, leaving neutral gray.

confusion colors  different colors liable to be mistakenly matched by persons with defective color vision, and hence used for detecting different types of color vision defects.

primary colors  a small number of fundamental colors; (a) in visual science, red, green, and blue, the colors specifically picked up by the retinal cones; (b) in painting and printing, blue, yellow, and red.

pure color  one whose stimulus consists of homogeneous wavelengths, with little or no admixture of wavelengths of other hues.

color dilution

reduction of the concentration of the color pigment in tissue; most important in hair and other fiber coats, in the skin and in the ocular iris.

color pigments

the pigments influencing skin color are melanin, melanoid, oxygenated hemoglobin, reduced hemoglobin, carotene.

color radical

color vision

the domestic animal species have limited color vision, the best perception being in bright light. Birds probably have the best, cattle and sheep the least, if any.
