This phenomenon of color perception, where opposite colors enhance or suppress each other, is explained by the opponent-process theory of color vision. This theory suggests that color perception is based on three opponent channels: black-white, blue-yellow, and red-green. The perception of color is the result of the balance between these opponent channels. So, a green square surrounded by red will enhance the perception of both colors, creating a stronger contrast between them, and making the green appear more vibrant. Similarly, a yellow square surrounded by blue will make the yellow appear brighter because blue and yellow are opponent colors. These phenomena cannot be explained by other color perception theories, such as the trichromatic theory or the complementary theory.
