Take a look at this picture and see if you can figure out who's hugging who. HOW DID THE GUY IN FRONT GET HIS FEET TO FACE BACKWARDS???!?!

People on the internet are freaking out about this optical illusion. The prevailing theory is that it just looks like that because the guy in front is wearing athletic shorts that are white on the inside and black (or dark blue) on the sides.

Mind F*ck of The Day: This Test Will Make Your Brain See Color in a Fully Black-and-White Photograph

Our brains are weird.

In a new BBC Four series, Colour: The Spectrum of Science, researchers show how the human brain is controlled by perception.

By watching the video below and staring at the blue dot in the center of the screen, a full black-and-white photograph will turn into full color.

It's science, man!

IFL Science explains:

It's all to do with our cone cells, one of the two types of photoreceptors within our eye's retina, which are responsible for color vision. We have three types of cones, which are sensitive to blue, green or red wavelengths of light. When we're exposed to a lot of one color, that particular type of cone gets overstimulated and becomes "tired" and unresponsive. This leaves you temporarily with the use of only your other two types of cone, which show the opposing "complementary" color (i.e red versus green and blue versus yellow). After a few seconds, the cones "recharge" and you're able to perceive that color again.

So...blue and black OR white and gold?
