The idea
Trichromatic theory holds that color vision arises from three cone types tuned to different wavelength ranges.
In practice
Any perceivable color can be matched by combining three wavelengths in the right proportions.
Where people slip
Trichromatic theory explains the receptor level and does not explain afterimages.
