Ebbinghaus Illusion Category: Size and Distance | Added: June 4, 2009 |
5 commentsThe Ebbinghaus Illusion, also known as Titchener circles is an image of two circles with additional circles around them. In this case the orange circle on the left is surrounded by large blue circles and the orange circle on the right is surrounded by small blue circles. But which is larger, the orange circle on the left or the orange circle on the right ? The answer is of course - they are both the same size.

Same Color IllusionCategory: Shape and Color | Added: June 4, 2009 |
12 commentsIn this picture the squares marked A and B are exactly the same color, despite the fact that A looks a lot darker than B. The fact that B falls within the shadow of the green object fools the eyes in to perceiving the shades of grey differently. It is in fact very difficult to see these two squares as the same color even when you are told that they are.
