The Science of Why No One Agrees on the Color of This Dress | WIRED

Not since Monica Lewinsky was a White House intern has one blue dress been the source of so much consternation.
(And yes, it’s blue.)
The fact that a single image could polarize the entire Internet into two aggressive camps is, let’s face it, just another Thursday. But for the past half-day, peopleacross social media have been arguing about whether a picture depicts a perfectly nice bodycon dress as blue with black lace fringe or white with gold lace fringe. And neither side will budge. This fight is about more than just social media—it’s about primal biology and the way human eyes and brains have evolved to see color in a sunlit world.
