Gray Bricks Illusion

Watch out everybody! We are near to break 8 million unique visitors! Let’s see who that lucky person will be. Really exciting, isn’t it? Let’s see what I brought you today… First I updated magic tricks website with hilarious David Blaine spoof, well actually a sequel to unbelievably popular original. Thanks to everyone that mailed me, informing me sequel exists. Those are some very talented actors, aren’t they? Then I found this illusion in my mailbox submitted by Nathan Corelli. It is really simple, yet hard to believe. Can you trust me when I quote Nathan that “both gray rectangles are of the same color”? Not so convincing, right? Well, actually if you’ve been with us from the very start, when we posted our first optical illusion, and few other similar ones, like for example “Which color is darker” and “Diamonds are Gray“, you’ll be able to understand the illusion immediately.

This is the explanation Nathan added: “The rectangle on the left is surrounded by white. The rectangle on the right is more surrounded by black. If the rectangles overlap you’ll see that they are identical. Colors appear lighter when they are surrounded by white, and darker when they are surrounded by black. This is a color comparison problem using two identical rectangles against a b&w background.”

  4. I just discovered somethis quite interesting.

    Try rotating your monitor 90 degrees in any direction (or use photoshop to flip the image.)

    To me it seems the effect mostly fades away when watching the stripes vertically instead. Can anyone explain why?

  5. This is the best darned illusion I have ever seen! But I have seen it lots of times before in different variations. There’s one where two circles look like they’re turning into a river that flows out to the ocean. That one is cool. If you could make these rectangles appear to bend into two rivers… Now THAT would be something!

    Kiddin’ of course… Nice illusion by the way… Makes you wonder how easy it seems to fool your brain.

  9. hehe. The first time I saw an illusion like that I had to open the image in an editor and compare the hex # for the two illusions before I believed the person showing it me. These are pretty damn cool.

  10. If you put your fingers over the black bars on the right you’ll see that they really are the same color!
