deception in visual sensation.




Color deceives.

It is almost impossible to see a color alone and it is almost always that we perceive many colors at a time. Referring to the Gestalt theory, we tend to perceive things as a whole. Therefore, we tend to see color as a whole. We see the interaction of colors. However, color deceives. People cannot remember certain color exactly as it is. Our visual memory is very poor. A single color can achieve many different roles. Same color, under certain situations, can be seen as many colors. Artists can make one color looks like two by altering backgrounds and the more different the backgrounds are, the stronger the influence they have. By contrast, two colors can be perceived as one. Different colors can look as if they are the same if place in different grounds. You should sometimes try it by yourself! Try to cut a piece of colored paper, place it on different grounds and amaze yourself how color deceives us!
