Young-Helmholtz theory of colour vision


A theory that there are three colour-perceiving elements in the retina: red, green, and blue. Perception of other colours arises from the combined stimulation of these elements; deficiency or absence of any one of these elements results in inability to perceive that colour and a misperception of any other colour of which it forms a part.

Synonym: Helmholtz theory of colour vision.
