Definition
Meaning and Definition
A person or organism whose vision uses three types of color receptors (cones) to distinguish colors; the standard condition for human color vision.
In biology and neuroscience, an individual with normal trichromatic color vision, as opposed to a dichromat (e.g., colorblind person) or tetrachromat (rare, with four cone types). Can also describe optical systems designed with three color channels.

FAQ
Frequently Asked Questions
'Trichromat' is a noun referring to the person or organism (e.g., 'She is a trichromat'). 'Trichromatic' is the related adjective describing the visual system or a process (e.g., 'trichromatic vision', 'a trichromatic printing process').
No. While all trichromats have three cone types, subtle genetic variations can cause slight differences in color matching and perception between individuals, even among those classified as having 'normal' color vision.
No. It is a highly specialized scientific term. In everyday language, you would simply say someone has 'normal color vision'.
Yes. Many primates, some marsupials, and various other species possess trichromatic vision. The term applies to any organism with a three-cone visual system.
