Why does the green dot illusion work?

The green dot appears thanks to an effect known as an afterimage. The rods and cones in our eyes adjust to the disappearance of the lilac dots after a few seconds and become tired. In the absence of the lilac dot, our eyes engage cones which process colors at the opposite end of the spectrum; in this case, green.
