Although surrounding colors can profoundly influence the appearance of a test color in the laboratory situation, these effects are seldom obvious in natural environments and probably represent an influence of the same processes responsible for color constancy. This concept refers to the fact that colors...
Rather than uniform representation of spectral information, the primary visual cortex (V1) exhibits asymmetric coding of different wavelengths of light: a strong bias on end-spectral colors (e.g., red and blue) relative to mid-spectral colors (green and yellow)6,7,8. Color opponency (red‒...

With respect to color vision research in Drosophila, it is important to note that spatial color contrast and color constancy, that are well documented in at least some insects including butterflies and bees have not been reported so far (reviewed in Chittka et al. 2014). In contrast, temporal...
Color Constancy Synonyms Chromatic adaptation;White balancing Definition Color constancy refers to the ability of the human visual system to perceive stable object color, despite significant variation of illumination. Color constancy is also a desired algorithm in machine vision. In image processing, it ...
Definition Color constancy is the ability to perceive colors as approximately constant even though the light entering the eye varies with the illuminant. Color constancy also names the field of research investigating the extent of this ability, i.e., the conditions under which a color is actually...
How the visual system processes color information and achieves constancy remains, however, a matter of debate. Two functional classes of color-sensitive neurons have been described [3]: Single-Opponent (SO) and Double-Opponent (DO) neurons. It has been sug- gested that SO cells are involved ...
