deuteranomaly


Show Summary Details

Quick Reference

A form of partial colour-blindness in which the proportion of green light required to be mixed with red to match yellow is abnormally high according to the normal Rayleigh equation, owing to a deficiency in the visual pigment that absorbs light in the middle part of the visible spectrum. Compare deuteranopia, protanomaly, tritanomaly. [From Greek deuteron second, alluding to the second of the three primary colours (1) red, green, and blue + anomalos uneven or inconsistent, from an- without + homalos even, from homos the same]
