{{main|Color blindness}}
A color vision deficiency causes an individual to perceive a smaller [[gamut]] of colors than the standard observer with normal color vision. The effect can be mild, having lower "color resolution" (i.e. [[anomalous trichromacy]]), moderate, lacking an entire dimension or channel of color (e.g. [[dichromacy]]), or complete, lacking all color perception (i.e. [[monochromacy]]). Most forms of color blindness derive from one or more of the three classes of cone cells either being missing, having a shifted [[spectral sensitivity]] or having lower responsiveness to incoming light. In addition, [[cerebral achromatopsia]] is caused by neural anomalies in those parts of the brain where visual processing takes place.

Some colors that appear distinct to an individual with normal color vision will appear [[metamerism (color)|metameric]] to the color blind. The most common form of color blindness is [[congenital red–green color blindness]], affecting ~8% of males. Individuals with the strongest form of this condition ([[dichromacy]]) will experience blue and purple, green and yellow, teal, and gray as colors of confusion, i.e. metamers.<ref>{{cite web |last1=Flück |first1=Daniel |title=Colorblind colors of confusion |url=https://www.color-blindness.com/2009/01/19/colorblind-colors-of-confusion/ |website=Colblindor |date=19 January 2009 |access-date=14 November 2022}}</ref>
