Checker shadow illusion

This is a pretty cool illusion, have a look at the squares marked ‘A’ and ‘B’ in the image above. They look like they are different colors but in actual fact they are not, they are exactly the same.
Placing the squares side by side as in the image below destroys the illusion. Try it yourself.
