Contrast and assimilation phenomena have a central role in the theories on the appearance of surface color. It is well known that principles of perceptual organization affect color perception. Paradoxically, the belongingness principle has been used to explain constrast as well as assimilation. In this paper, we try to solve this paradox by arguing that assimilation occurs earlier during the formation of perceptual groups, whereas contrast occurs after the formation of perceptual groups.

Abstract
Contrast and assimilation phenomena have a central role in the theories on the appearance of surface color. It is well known that principles of perceptual organization affect color perception. Paradoxically, the belongingness principle has been used to explain constrast as well as assimilation. In this paper, we try to solve this paradox by arguing that assimilation occurs earlier during the formation of perceptual groups, whereas contrast occurs after the formation of perceptual groups.
