According to the work of White (1979), the background is a grating of black and white stripes, whose gray segments differ in hue based on the stripes they replace. This change in hue is deemed to be a result of contrast and assimilation. This chapter discusses the lightness illusion of White further by presenting a number of experiments that show the relation of White's effect on spatial frequency, contrast and assimilation, and apparent motion.

Keywords: White's effect; contrast; assimilation; spatial frequency; apparent motion
