Opponent-Process Theory
Captions available
The idea
Opponent-process theory holds that color is encoded in opposing pairs — red against green, blue against yellow, black against white.
In practice
Staring at a red shape and looking away produces a green afterimage of the same shape.
Where people slip
Opponent-process and trichromatic theories are not rivals. They describe different stages of the same pathway.
