Bezold–Brücke shift

The Bezold–Brücke shift refers to a phenomenon in color perception where the perceived color of a stimulus changes depending on the surrounding colors and the intensity of the light. This effect is related to the way that the human visual system processes color in different contexts. Specifically, the Bezold–Brücke shift illustrates how the perceived hue of a color can change when its brightness is altered or when it is placed against different background colors.
