What is Trichromacy?
[[File:Cone-fundamentals-with-srgb-spectrum.svg|thumb|Response of different human cone cells to different wavelengths of light]] '''Trichromacy''' is a type of [[color vision]]. [[Animal]]s with this kind of vision see colors with [[cone cell]]s in their [[retina]]. The three types of cone cell are sensitive to different [[wavelengths]] of light. Color is constructed in the [[brain]]'s [[visual cortex]]. [[Human]]s and many other [[primate]]s have full color vision.<ref>Rowe, Michael H 2002. Trichromatic color vision in primates.

Most other [[vertebrate]]<nowiki/>s such as [[lizard]]<nowiki/>s and [[bird]]<nowiki/>s have four types of cone cells, hence can discriminate more colors than humans can. == References == {{reflist}} [[Category:Color]] [[Category:Vision]] {{biology-stub}}
