negative afterimage

   Also known as Purkinje afterimage. The adjective negative refers to the fact that the colours of this type of * afterimage are complementary to the colours of the primary stimulus. The term negative afterimage is used in opposition to *positive afterimage, a term that is reserved for duplicate images that have the same relative brightness relations as the perceived object or stimulus. The negative afterimage is usually classified as a * physiological illusion.
