Helmholtz–Kohlrausch effect
The Helmholtz–Kohlrausch effect (after Hermann von Helmholtz and Rudolf Kohlrausch) is an entoptic phenomenon wherein the intense saturation of spectral hue is perceived as part of the color's luminance. This brightness increase by saturation, which grows stronger as saturation increases, might better be called chromatic luminance, since "white" or achromatic luminance is the standard of comparison. It appears in both self-luminous and surface colors, although it is most pronounced in spectral lights.
