The Abney Effect relates to color perception. The term appears to cover two phenomena.
- Specifically the Abney effect relates to the apparent shift in hue of monochromatic light when white light is added. That is, a blue light would seem to become more red when white light is added.
- It also relates to the perceptual illusion that happens when a large area is suddenly illuminated. The light appears to come on in the centre of the area and then spreads to the edges. Conversly if the illumination is suddenly turned off the edges disappear first as the light then disappears at the centre.
