Mach effect

The Mach effect, named after the Czech physicist Ernst Mach (1838 to 1916), is a sensory-psychological visual impression that causes the viewer to perceive brightness transitions with a higher contrast than is actually present.

Contrast enhancement causes the edges between brightness differences to be perceived more clearly by the viewer.

The Mach effect is about the transition between two monotone color patches being interpreted to mean that the dark color patch is perceived as having an even darker edge and the color patch with higher brightness is perceived as having a brighter edge. As a result, the borderline between two color areas is perceived more clearly.
