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.

    They're not "the same image", they're obviously two different images of the same exact dress. The one on the right is washed out because of overexposure. It's also obviously (washed-out) blue and (washed-out) black.

    Tell me, have you ever seen supernatural phenomena?
