Afterimage is a visual illusion where an image continues to appear in one’s vision after the original stimulus has been removed. This phenomenon occurs due to the persistence of retinal cells responding to light even after the stimulus is gone, leading to a temporary ghost-like image. Afterimages can be positive, where the colors of the original stimulus are preserved, or negative, resulting in inverted colors. The duration and intensity of afterimages depend on various factors such as the brightness and duration of the initial stimulus and individual differences in visual perception. Illusionists have utilized afterimages creatively in magic tricks.
