Are people seeing different colors on the same screen?
I don't get the joke. All I see is a white and gold dress. What's the gag?
You blue and black'ers have your computer monitors set wrong... and it's a bad picture.
It's really a white and gold dress photographed from a small aperture camera with too much back-light combined with poor white balance causing the gold lace to look brown which shows blackish on screens with poorly set contrast while the main white fabric comes across with bluish tint because of the over saturated backlight which is made worse with LED backlit screens which have a blue tint to their "white" or LCD's with incorrect color settings or "boosted" colors.
Or it's a blue and black dress shot with too high of an ISO or a crappy cellphone with poor flash correction...
Or it was altered in Photoshop.
Looks light blue with brown lace to me, but I'm partially color blind.
