It's an optical illusion because of the way your dumb friend's eye is sending information about light to her dumb brain.
So you're telling me no one else sees pink and green? (via swiked)
If you haven't been following the international controversy about this dress, take a minute to catch up.
All you really need to do is ask yourself what colors you see: blue and black or white and gold? If you see white and gold first, relax. You're normal. Because that's what I saw first. I told myself that anyone who saw blue and black was a liar and a thug. I told myself I'd never change.
Then, while researching this important story, THE DRESS CHANGED COLOR.
Suddenly, I could only see it as black and blue! When I woke up this morning, it was back to gold and white and has since changed back to black and blue again. Is it any wonder people are freaking the eff out about this dress?

Anyway, the folks over at Wired have explained what's going on using some technical sounding language meant to put your mind at ease. First, they explain how our brains perceive color:
Light enters the eye through the lens—different wavelengths corresponding to different colors. 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. Critically, though, that first burst of light is made of whatever wavelengths are illuminating the world, reflecting off whatever you're looking at. Without you having to worry about it, your brain figures out what color light is bouncing off the thing your eyes are looking at, and essentially subtracts that color from the “real” color of the object.
