Shiny legs or painted legs? Internet's newest obsession

We all remember where we were when the internet posed the question: is the dress black and blue or white and gold?

While that color debate has some of us divided to this day, there is a new, and possibly less contentious, optical-illusion that social media is obsessing over now.

Allow us to present: shiny legs.

Or are they?

At first glance, the now-viral Instagram photo shows a pair of legs that appear to be shiny and oiled up.

But if you look closer, you'll see the shine is actually just streaks of white paint.

The difference between the dress and the legs comes when you consider what you initially saw.

Apparently most of us see shine on first glance, but once it's apparent the legs are actually paint-stained, it becomes almost impossible to see them as oiled up again.

This is a fact psychologists chalk up to "sensory cues."
