GREENE: You're wrong, Linda, it is totally white and gold - whatever. This image we're looking at here was posted on Tumblr. People online took sides and yelled at each other. Wired magazine put a neuroscientist and a photo editor on the case. They say the dress is blue, and they are wrong. It's MORNING EDITION. Transcript provided by NPR, Copyright NPR.
