The adaptive significance of the unique ability in many primates to distinguish red hues from green ones (i.e., trichromatic color vision) has always enticed debate among evolutionary biologists. The conventional theory is that primates evolved trichromatic color vision to assist them in foraging, specifically by allowing them to detect red/orange food items from green leaf backgrounds. However, the results from several empirical studies have called into question the extent to which trichromacy functions in foraging and if it provides a performance advantage over dichromatic primates (who lack red-green color vision). Other studies have suggested that trichromacy evolved in primates so that they could use physical traits like red skin in socio-sexual communication, such as a male providing information to a female about his mate quality.
