The illusion presented here is very interesting. Looking at the below squares the center appears white while the outer area appears to be painted with a slight water color hue. In fact the outer area is white the same as the center. Learn more...

After Image Optical Illusion (painting with your eyes)

The next two optical illusions are simple after image illusions but presented in a new way.

The nature of this optical illusion is to paint a gray scale image using only your eyes.

The two illusions are composed of two images. The first is a negative image and the second is a gray scale image. Stare at one spot in the center of the negative photograph for 30 to 45 seconds. Then after the time is up slide your mouse over the photograph. The image flips to the gray scale and if you hold your focus the image will seem to be a full color photograph (not gray).

The longer you look at it the more pronounced the effect.

I created the below illusion as part of a "how to create your own optical illusion" post. As a matter of fact I created this primer on how to create this illusion before any of the similar illusions popped up on the web. Want to make your own click to learn more.

The same instructions apply to this image.
