The phenomenon described is an example of an afterimage, which is best explained by the Hering opponent-process theory of color vision. This theory suggests that color perception is controlled by opposing pairs: red-green, blue-yellow, and black-white. When you stare at a red object, the red photoreceptors become fatigued, and when you look away, the opposing green photoreceptors dominate, creating a greenish afterimage.
