Look at the image in this post very closely. Are you seeing color? You're not alone, even though this is a black-and-white photograph that uses an optical illusion to make your mind see more color than is actually there.

Look closer and you'll see that the black-and-white image is overlaid with a colored grid that makes it appear there is color in the shirts of the kids in the image. Pretty neat trick, right?

The image was shared over the weekend by Lionel Page, an economist at UTC Economics and it quickly went viral, garnering over 37,000 likes and 17,400 retweets.

Just goes to show, you can't believe everything you see!

This is a black and white photograph. Only the lines have colour.

What you “see” is what your brain predicts the reality to be, given the imperfect information it gets. pic.twitter.com/gwttlcC2Zw
