WebOct 2, 2008 · Old World monkeys, apes, and humans all enjoy trichromatic color vision (Jacobs 1993), but most terrestrial mammals are cone dichromats, and like the small percentage of humans with dichromatic vision, they likely can distinguish only a limited number of colors (Peichl et al. 2001; reviewed by Jacobs 1993). WebHuman dichromats have especial difficulty in detecting coloured fruit against dappled foliage that varies randomly in luminosity; it is suggested that yellow and orange tropical fruits have co-evolved with the trichromatic colour vision of Old World monkeys.
WebAM: “Trichromatic” refers to a color vision system based on three different types of cone cells in the retina. Each cone type is maximally sensitive to different wavelengths of light, roughly corresponding to blue, green and red hues. In dichromacy, there are two types of cones cells. In primates there [is] one blue-sensitive type and other ... WebSome of them are dichromatic and others are trichromatic. Most females i n some species can distinguish reds but no males can.
