The Confetti illusion

The Munker illusion, which produces two apparently different hues from a base color, can be extended to multiple apparent colors. By having foreground stripes in more than two colors, it is possible to create multiple foreground colors that lead to multiple apparent hues in the base objects. All of these apparently different colors are due to color assimilation rather than to differences in luminance, as in the Munker-White illusion. This technique works well for three colors and can be extended to four and even six colors.
