Opponent-process theory is a psychological and neurological model that accounts for a wide range of behaviors, including color vision. This model was first proposed in 1878 by Ewald Hering , a German physiologist, and later expanded by Richard Solomon , a 20th-century psychologist.
The opponent process is a color theory that states that the human visual system interprets information about color by processing signals from photoreceptor cells in an antagonistic manner. The opponent-process theory suggests that there are three opponent channels , each comprising an opposing color pair: red versus green , blue versus yellow ...
Exploration of the color space outside the range of "real colors" by this means is major corroborating evidence for the opponent-process theory of color vision. Chimerical colors can be seen while seeing with one eye or with both eyes, and are not observed to reproduce simultaneously qualities of opposing colors (e.g. "yellowish blue"). [7]
Opponent process theory Two complementary theories of color vision are the trichromatic theory and the opponent process theory. The trichromatic theory, or Young–Helmholtz theory , proposed in the 19th century by Thomas Young and Hermann von Helmholtz , posits three types of cones preferentially sensitive to blue, green, and red, respectively.
The proponents of the opponent process theory believe that these hues cannot be described as a mixture of other hues, and are therefore pure, whereas all other hues are composite. [1] The neural correlate of the unique hues are approximated by the extremes of the opponent channels in opponent process theory. [2]

The pair conducted important research that quantified the opponent process theory of color vision. Hurvich and Jameson's adaptation of the opponent process theory became known as a more complete explanation of color vision than the Young-Helmholtz theory. [5] Hurvich was elected to the National Academy of Sciences in 1975. [6]
