Color scientists already have a word for it: Dressgate. Now the Washington Post reports that a puzzling thing happened on Thursday night consuming millions — perhaps tens of millions — across the planet and trending on Twitter ahead of even Jihadi John’s identification. The problem was this: Roughly three-fourths of people swore that this dress was white and gold, according to BuzzFeed polling but everyone else said it's dress was blue. Others said the dress could actually change colors. So what's going on? According to the NYT our eyes are able to assign fixed colors to objects under widely different lighting conditions. This ability is called color constancy. But the photograph doesn’t give many clues about the ambient light in the room. Is the background bright and the dress in shadow? Or is the whole room bright and all the colors are washed out? If you think the dress is in shadow, your brain may remove the blue cast and perceive the dress as being white and gold. If you think the dress is being washed out by bright light, your brain may perceive the dress as a darker blue and black.

According to Beau Lotto, the brain is doing something remarkable and that's why people are so fascinated by this dress. “It’s entertaining two realities that are mutually exclusive. It’s seeing one reality, but knowing there’s another reality. So you’re becoming an observer of yourself. You’re having tremendous insight into what it is to be human. And that’s the basis of imagination.” As usual xkcd has the final word.

    You don't get to say what thy might have been before they were washed out.

    All you get to say is that the photos viewed side by side look the same to you.
    That is the claim YOU MADE.

    Now you tell me the the photo is washed out. Yet they look the same to you (or so you say).
    If that were the case, you would not be able to say one was washed out. So clearly the DON'T
    look the same to you, which means you've been lying all along.

    I think you have psychological problems and should see a counselor.

    I never said they look exactly the same, just that they look the same: they're the same dress and the same color. One photo is merely overexposed.

      He has psychological problems? Who are you to make that judgment? Aren't you the one who I've seen supporting systemd around here and at Slashdot?

      Fading would not turn blue and black into gold and white. Only inverting would. Not only do you seem to be colour blind. You are also ignorant of basic color theory.
