~Checker Shadow illusion~

By: Nick A

The A and the B square are the same color

Don't believe me? here's proof.

~Explanation~

there are many tricks in this picture. First of all, our mind immediately knows that objects are dimmed under a shadow.

Second, the B square is surrounded by darker squares, which by contrast makes it look much lighter, and A is surrounded by lighter squares which by contrast makes it look darker.

Third, your mind expects them to be opposite colors because it looks like a checkerboard and B is in a spot where it should be white if A is black.
