The question what "what color is this dress" so we answered as to what we saw. What the color of the dress is in that picture given. Using deductive reasoning, the picture is overexposed, looks like it's in a yellowish room, with a window probably casting natural sky light onto the dress. This gives it the blue-ish and gold color. It never said "what color is the actual dress right here irl I never bothered taking another photo".
