Afterimage
An image that is perceived after the actual image is no longer present. An afterimage normally occurs when you have stared at an image for about a minute. In the case of positive afterimages, the image has similar brightness and colors to the original. Negative afterimages occur more frequently: when looking at a white surface, the image previously viewed appears there in the respective complementary color. Afterimages are caused by the "overfatigue" of the photoreceptors, which stop sending signals to the brain after a certain period of viewing.
