I had to check it as well.
that is cool
I quite like the first one, I found a really cool one once I will try and find it and post.
Wow, that is on of the weirdest things I ever seen.
Fired up Photoshop, and like everybody else saw, the colors are the same.
No wonder I don't get any work done - had to check this too for myself :)
If you copy the colour of square A onto a square on a new layer in Photoshop, then drag this new square across the original layer, it gives you a clear idea as to how the eye is tricked.
Must be that the eye is particularly bad at differentiating shades of gray, and only registers gray in comparison to being a colour darker than or lighter than the surrounding shades.
Mind you the human mind is also bad at differentiating shades of gray - hence we tend to present information as either black or white. ;)
Gray squares.. amazing.
I must upgrade the buggy OS of my eyes, no doubt. :)
That blew me away!
I took it into photoshop and cut them out and placed them side by side:
B looks so much lighter, doesn't it?
OK, not that I didnt trust anyone, but it into Photoshop also. That is absolutely wild, the same exact color. I printed out the first one to take to work tommorrow, see how many people I can get to fall over staring at it. LOL
Thanks for sharing it.
Hehe, did the same thing with the GIMP. very cool!
What is amazing is how little of the image needs to be shown to cause that illusion.

littleman, even more stunningfor me ws when i opened it in psp, then ZOOMED 3 or 4 times so only those 2 squares fit on screen and it still looks totally different color!
also what i did now is to copy some little square(not all square but jsut little cut out,scrap ) from zoomed pic A and hold it in my mouse (you know ready to paste). then moved it on square A and then on square B and it is the same color:)
I guess context is everything, isn't it?
The first one really made me laugh. That is a very cool illusion. The second one has me thoroughly confused. I too checked it in photoshop and my mind can't seem to grasp how on earth they are the same colour ... but they are! Totally freeky!
