The color dove illusion is a type of a positive afterimage. The color dove illusion can be obtained with different colors and spatial surrounding regions. In this illusion the disappearance of a colored background causes an empty shape to obtain the hue of the disappeared background. The effect can be obtained even when the surrounding background area is relatively thin and when it is presented for a very short duration. This illusion occurs only when the contour of the empty shape remains after the background disappearance. Thus the color dove illusion is a positive aftereffect, which is different from classical positive aftereffects. The parameters of the color dove illusion as well as variants, such as the flickering variation, are discussed. Related concepts such as simultaneous contrast and spatiotemporal edge are discussed

Keywords:   afterimage, illusion, color dove illusion, simultaneous contrast, spatiotemporal edge
