The same color illusion—also known as Adelson's checker shadow illusion, checker shadow illusion and checker shadow—is an optical illusion published by Edward H. Adelson, Professor of Vision Science at MIT in 1995.[1] The squares A and B on the illusion are the same color (or shade), although they seem to be different. This can be proven by sampling the colors of A and B in an image-editing program. By erasing everything except the two labelled squares, the illusion can be dispelled.
