[VIDEO] What Color Are These Hearts?

A baffling optical illusion is showing us how little we know about how our brains actually function.

 

The two hearts in the image appear to be totally different colors - one purple and the other a bright orangey red.

 

However, the two hearts are in fact precisely the same hue - a vivid pink.

 

In fact it is the placement of the geometric stripes that fools our brains into seeing something which isn't really there.

 

This gives us a vital clue to how our vision works. It suggests that we perceive an object's color based on its proximity and contrast with surrounding shades.
