Colour illusions and the human visual system

Visual illusions have always been a fascinating subject of study. However, they are more than just fascinating; they reveal insights into an understanding of our vision system. We will show a selection of colour illusions, representative of various mechanisms of our visual system. The visual process begins in the eyes. The receptive fields situated on the retina enhance the detection of edges, and continue to our brain. Then, a range of mechanisms take place, including: colour constancy, simultaneous contrast, assimilation; these contribute to the complex visual process that ensures a robust sensing of our world.
