The phenomenon described is the afterimage effect, which is best explained by Hering's opponent-process theory of color vision, where there are opposing processes for perceiving color - red vs. green, blue vs. yellow, and black vs. white. When you stare at a red object, the green receptors in your eyes get fatigued, causing a greenish afterimage to appear when you look at a blank white surface.
