can you believe that "A block" and "B block" is a same colors? :boogie:

Uh... maybe the letters are, but the blocks look like two different shades of gray to me. What's up? Is it that they're both gray? :dunno:

^ those gray boxes are same,
if you have a photoshop, then open that picture with it and use/check with eyedropper tool.
you will get same color code from both.

check this picture,
I just copied block A and pasted twice

I couldn't believe it but it is!

thanks for the share... jus crazy man

amazing!

:wow: Who thinks this stuff up???

Whats really crazy, is that even after seeing the solution and understanding that both A & B are the same color, when one goes back to the original, its impossible for the mind to 'see' the same shade of grey in the A & B squares.

Interesting paradox, we knows its wrong, yet we can't see it right...

Try saving the image to edit and cutting out a piece of B and dragging it over A. You'll see the shade of gray change gradually. Trippy.

Probably because the human brain sees the pattern before the color. Because once you destroy the pattern, you will see the same color.
