Description Presented here is a vast gallery of many different forms of Optical Illusions. Whether these optical illusions are conveyed through fractals, photographs, architecture, art, or old fashioned pen and ink, they are bound to remind you that "seeing is not believing."

Caution!!!! Some of the optical illusions on this blog may cause dizziness or possibly epileptic seizures. The latter happens when the brain can't handle the conflicting information from your two eyes. If you start feeling unwell when using this website, immediately cover one eye with your hand and then leave the page. Do not close your eyes because that can make the attack worse.

Straight Red Strips?

Here is an optical illusion created by Herman J. Verwaal from his deformation series

Herman points out the red strips appear to be deformed where they cross the fluorescent lights. I agree the red strips seem to narrow as they cross the lights. Even more fascinating to me is that the red strips seem darker where they cross the lights. Yes the red strips only seem darker.

The fact is that the red strips have a red green blue measurement of R:246, G:4, B:0. No matter where in the strip you measure the color is constant. I find this fascinating because the red in each strip, where it crosses the light, appears to darken.

The bottom line is that the red strips above are perfectly straight and the shade of red does not change at any point in this image.

Herman has an excellent collection of Pop Art, Paintings, and Optical illusions. He has given me permission to feature his pieces here. This is just one of many. His illusion art ranges from color perception to distorted illusions.

Thank You for sharing these excellent illusions Herman.
