#95 : Same Coloured Dogs?

There are many different types of illusion. Physical illusions are illusions where something has happened before the light reaches the eye, such as a rainbow. Physiological illusions are the effects on the brain by stimulation of a specific type such as brightness, colour and movement. Visual cognitive illusions are those that go against what we perceive as logic, and can continue to confuse us even when we know the trick.
