What colour do you see?

colour of the dress

It’s odd how this picture has gone viral. I saw it on Reddit, Twitter, Facebook, Google Plus and even on a blog, which just goes to show. Blogs are still hip.

Anyway, I see blue and black, but some people see white and gold. My son looked at the exact same screen I was looking at, but at an angle and said he saw brown and white. When he moved around he said he saw some blue but it was still mostly white. Odd.

Steven Novella has written a good post on this and explains why our brains see this difference. Wired have a good article too. It’s an optical illusion. Just like these:

The two objects are the same colour. Cover the middle join with your finger.

Are Squares A and B the same colour?

At least we can all agree on one thing: The people who see the dress as white are utterly, completely wrong.

Can your car roll uphill?

Good explanation of this strange phenomenon 🙂

Whilest there is this slope of 1 in 86 upwards from the bend at the Glen, the configuration of the land on either side of the road provides an optical illusion making it look as if the slope is going the other way.

There’s even a Wikipedia page on the phenomenon.
