Tritanopia is a severe form of blue-yellow color blindness, in which the S-cone is absent. It is much rarer than the other types, occurring in about 1 in 100,000, but is not sex-linked, so affects females and males at similar rates. They tend to confuse greens and blues, and yellow can appear pink. Normal sight.

Dichromacy - Wikipedia

WebRed-green color vision defects. Among mammals, trichromatic color vision occurs only in primates. The majority of mammals have a reduced form of color vision called dichromacy (Jacobs, 1993, 2024 ). Dichromatic color vision is based on only two different cone types, usually an S cone and a single L/M cone. Web( ˌdaɪkrəʊˈmætɪk) adj 1.
