People can't tell whether this is a photo of a door or a beach — can you?

• 9GAG, an image-sharing website, just tweeted a brainteaser that's tearing the internet apart.
• The tweet asks if readers can tell whether a photo is of a rotated beach or a close-up of a bright  blue door.
• Obviously, the internet had opinions, but a conclusive answer was decided on.
  

On August 27, 9GAG tweeted a photo of what appeared to be a sideways photo of a beach — or a bright blue door next to a white wall.

If you can't see the beach, try tilting your head to the left — the bright blue is the sky, the turquoise is the ocean, and the white is the sand. If you can't see the door — the wall is the white, the turquoise is the door-frame, and the bright blue is the actual door.

The internet, obviously, was divided.

But the internet is also full of great detectives. One eagle-eyed Twitter user pointed out that the photo had been altered to take out the beach-goers, and that's why it was confusing.

No matter what it is — our brains still hurt.
