Assimilation Illusion

This illusion is so called because of the tendency of the eye to assimilate various colors into a single perception. As long as the inner shape is recognized as such, the two colors it consists of mix in the eye as well as the two colors of the outer shape. As the result, the two gray colors are perceived as different.
