Go grab a piece of paper and write down the colour of the dress in the image in the left, and then click read more. Simple, isn't it? Or so you think...
You either thought the colour of that dress was gold and white or blue and black. Do you want to know what colour it really is? Before we find out...
Let's see what some celebrities had to say on the matter...
Taylor Swift says:
"I don't understand this odd dress debate and I feel like it's a trick somehow. I'm confused and scared. PS it's OBVIOUSLY BLUE AND BLACK"
Justin Bieber says:
"And for everyone asking I see blue and black"
Kim Kardashian says:
"What colour is that dress? I see white and gold. Kanye sees black and blue, who is colour blind?"
It's actually BLUE and BLACK! Now, this might seem crazy to those people who saw white and gold stripes, but it's true!
I bet you want to know the explanation. You're probably thinking: "But it's gold and white! I just know it! People are CRAZY if they think it's blue and black!"
Here's the science behind it: “Light enters the eye through the lens — different wavelengths corresponding to different colors,” writes Wired’s Adam Rogers. “The light hits the retina in the back of the eye where pigments fire up neural connections to the visual cortex, the part of the brain that processes those signals into an image."Usually this process works fine, Rogers writes, but the image of this particular dress is “some kind of perceptual boundary.”“What’s happening here is your visual system is looking at this thing, and you’re trying to discount the chromatic bias of the daylight axis,” Bevil Conway, a neuroscientist who studies color and vision at Wellesley College, told Wired. “So people either discount the blue side, in which case they end up seeing white and gold, or discount the gold side, in which case they end up with blue and black.”
I didn't understand that at all. Did you? Here's a simpler explanation. So usually when you see a picture or something, the light hits your retina which is way at the back of your eye and then it sends signals to the brain, so your brain can tell you which colour it is. But in this optical illusion, different people see different colours because their brains work in a different way. I think.
