Young-Helmholtz theory of color vision

Young-Helm·holtz the·o·ry of col·or vis·ion

(yŭng helm'hōlts), a theory that there are three color-perceiving elements in the retina: red, green, and blue. Perception of other colors arises from the combined stimulation of these elements; deficiency or absence of any one of these elements results in inability to perceive that color and a misperception of any other color of which it forms a part. Synonym(s): Helmholtz theory of color vision
