  • Alright, so the world has seemingly become utterly divided on this dress.

  • What colors do you see?

  • On the one hand, we have team black and blue; on the other, team white and gold.

  • We asked on Twitter and got hundreds of responses for both white and gold, and black and blue.

  • For what it's worth, we both saw black and blue and thought this was a massive prank at first.

  • So how can it be possible for people to see it so differently?

  • It's a phenomenon known as color constancy.

  • Take this cube for example.

  • The middle square on the top appears to be a shade of brown, while the one on the side looks much more orange, but in actuality, they're both the exact same color.

  • We promise we haven't cheated here or done any trick photography.

  • Instead, our brain looks at the context , sees a shadow, and instantly thinks "Oh, shadows make objects appear darker."

  • And so the brain compensates and interprets this square as later than it appears, until the shadow is taken away.

  • Back to the dress, and we have a similar situation, except here the context is very arbitrary.

  • We're so close up to the dress that we don't really know its surroundings and the brain has to make assumptions.

  • People who picture the dress as white have brains which may be interpreting the dress in the blue lit room for example.

  • As in its near window with a bright blue sky.

  • It makes perfect sense then that the white dress would be tinted blue, and that the gold color wouldn't really change.

  • On the other hand, the brains of people who see it as black and blue may be interpreting the dress in an artificially lit setting, like summer with the yellow lights.

  • As the result, the brain sees the gold as just a reflection of the black and believes that the blue has been unaffected.

  • Chances are that this image just happens to be perfectly ambiguous to our brain,

  • meaning it all comes down to individual perception and even how and where you view the image.

  • From a factual standpoint, the dress is blue.

  • In fact, here are some other pictures of it.

  • But, this is a beautiful example of how our brains have evolved to interpret the world around us without us even realizing.
