It's true. I compared them in photoshop. Check this out:

The human brain still makes them look so different.....

That gave me a headache.

Why are we so easily fooled by optical illusions?

the brain sees the begining of patterns and quickly assumes the rest of it there fore, even though you know they are the same, you also know that horizontally and vertically adjacent tiles on a checker board are always different colours - you brain overules with it's most well known patteren and there you go.


I think....

Why are we so easily fooled by optical illusions?

Because we perceive the image as being three-dimensional (after all, it looks like a perfectly plausible 3D scene). In a three-dimensional world, color is relative... we'll perceive a white object as white, even if viewed under a colored light. The object doesn't appear white any more, but relative to other objects, it does.

Similarly, our brain "knows" that objects in shadows are lighter in color than they appear. So we perceive the color of square B to be much lighter than it actually is since it's shadowed. Square A is not shadowed, and is perceived as the color it actually is, or a very close color. Both colors are interpreted relative to the surrounding squares. The fact that the shadow has soft edges adds to the illusion... the light non-shadowed color blends into the dark shadowed color smoothly. Our brains see this blend as indicating that the shadowed and non-shadowed portions of the same square are the same color (which they would be in the real world).

Umm waht resolution and Color settings are you guys using, becuase I did it in paint on High color (16-bit) 800X600 and it is NOT the same color...................... (of course it being or haivng been a jpeg may have somethign to do with that)

Use 32-bit color. Also, Paint sucks for checking stuff like that. I checked it in PSP, and they are the same color. The color picker showed me they had the same RGB components. Crazy. The brain is so focused on the checkerboard pattern that it alters your perception.
