Opponent process - History
The opponent colour theory was first proposed by Ewald Hering in 1872 (Hering, 1964). He thought that the colours red, yellow, green, and blue are special in that any other colour can be described as a mix of them, and that they exist in opposite pairs. That is, either red or green is perceived and never greenish-red. (Note that although yellow is a mixture of red and green in the RGB color theory, the eye does not perceive it as such.)
In 1957 Leo Hurvich and Dorothea Jameson provided quantitative data for Hering's colour opponency theory (Hurvich et al., 1957).
The opponent colour theory can be applied to computer vision and implemented as the Gaussian colour model (Geusebroek et al., 2001).
