Perception

Bird in a Cage

BIRD IN A CAGE produces a color afterimage in the eye. If you stare at the red bird for 15 to 30 seconds and then switch your view to a white wall, you will see an image of the bird in its complementary color (in this case, blue-green). A green bird produces a magenta afterimage. This effect results from your eyes adapting to a particular color, so that when you look at something else, like a white wall, you'll see everything but that color.
