Quizplus · Accepted Answer

The process described in the question, of mixing three primary colours to recreate the visible spectrum, is a key principle of the trichromatic theory of color vision. This theory posits that there are three types of color receptors (cones) in the retina that are sensitive to different wavelengths of light, and that all colors are perceived through combinations of activity in these three types of cones. This is supported by physiological and behavioral evidence, and is widely accepted as the basis of human color vision.
