It is hard to believe that the top and bottom of the middle squares are actually the same shade. In order for me to see this, I had to use my finger to cover the area on my computer screen where they join. Then it was clear that they are actually the same color. This fascinating optical illusion has become one of my personal favorites.
About the Brightness Illusions (Green Square)
I have learned that this Brightness Illusions artwork is trying to show that the entire concept of an illusion is based on delusion. Through this optical illusion artwork, Beau Lotto is trying to help the viewer to realize that a person can see an illusion whenever the two realities are being entertained simultaneously. Such illusion artwork will help the spectator realize more wonderful things about the brain. The brain is a naturally creative and inquisitive tool that endlessly redefines normality which is essentially relative and historical. This Brightness Illusions will let the viewer realize the influence of color, motion as well as shape in an illusion.
Gaze cautiously at the two big squares in the middle to the image. At first look, one square looks like a light green and the other one is dark green. However, if you look closely, both squares are exactly the same color.
