Color appearance phenomena
Bezold–Brücke shift
(Luminance on hue effect)
The appearance of a color's temperature or hue changes as the intensity of light changes.

How it affects UI design
When creating a color scale, or making tints, cool colors should shift towards warmer hues as they get lighter if you want colors to emulate properties of the physical world.
