The refraction of light can cause rainbows and mirages, two illusions that are dependent on the atmosphere. They can occur for many reasons, such as the effect of light on an object, insufficient sensory information about an object, or errors in an individual’s processing of sensory details.

As the examples below show, colors can change dramatically against different backgrounds. Changing a color’s appearance by changing the background or lighting is one of the most common techniques in optical illusions. So for those who see it as white, your eyes may be subtracting the wrong background and lighting. The Ponzo Illusion was first published in the book Intorno ad alcune illusioni nel campo delle sensazioni tattili, sull’illusione di Aristotele e fenomeni analoghi in 1910. The Ponzo Illusion was discovered by Mario Ponzo (1882 – 1960), an Italian psychologist. Foreground objects trick our brain into thinking the moon is bigger than it really is. Some researchers believe that the Moon illusion is an example of the Ponzo illusion, with trees and houses playing the role of Ponzo’s converging lines. This involves a bisecting component that causes the bisecting line to appear longer than the line that is bisected. The vertical–horizontal illusion is the tendency for observers to overestimate the length of a vertical line relative to a horizontal line of the same length.
