This illustrates color constancy, which is the ability to perceive the true color of an object regardless of the lighting conditions. Even though the bluish light would normally make the apple appear blueish, our visual system adjusts for the lighting and we perceive the apple as its true color, which is red. This is an example of color constancy.
