first off: obviously the true colors of the dress are blue and black nobody is denying that @ all the tryhards saying it has to be blue/black because they know what the real color
but based off the picture, even knowing the lighting is the sole reason that the colors look different from what they are...
when I saw it I thought it looked like a greyish blue and like brownish gold and my sister said it was blue and black... according to her it's just a bad picture of why the black looks brown or gold to some people.
