Mach bands: Why do the bands of light and dark appear at the margins of shadows?

Mach bands are the phenomena that had been used consciously or unconsciously by artists for millennia, and an optical illusion where a band of gradients will appear in places to be lighter or darker than they actually are. Mach bands, as well as numerous other visual and perceptual illusions, provide a valuable way to investigate how the eye and brain process visual information. Equally, they are used by artists for visual effect, entertaining and satisfying the endless fascination human beings have with novelty and creativity.
