I was more amazed by the first one. The third one is cool, but it seemed pretty apparent that my mind was trying to remove the effect of the purple and yellow filters. Maybe it's just me, but I liked the first one better.

I think the first one is some kind of computer rigged trick. I still don't believe it.

Cover it with your hands or your weiner or something. They are the same.

Illusion 1 is definitely the most striking.

Like PairTheBoard, at first I couldn't believe it and wondered about a "computer trick."

So I used a screen capture program to grab a patch from each square and pasted them into a graphics program side-by-side.

The squares are identical in color. Both have RGB mixes of 107 - 107 - 107 and Hue/Sat/Lum of 160 - 0 - 101.

I smell a wagering opportunity here.

Great illusions, thanks.

Wow, check this out from OOT. Amazing. I've never seen anything like that. Be sure to give it a little time with your eyes closed.

ok, this is some kind of gullibility joke right? I did physically cover everything around the two patches. A is definitely a darker shade of grey than B is. Covering their surroundings does not change my perception of their shades AT ALL!
