Gold/tan and white. It's in the shade and that throws off the white some.

I saw it White and Gold at first then when I clicked on the link and saw it Black and Blue I came back and it was Black and Blue and then it changed back to White and Gold. lol

Its color depends on the lighting, I believe. One of those trick dresses that make it look like its a different color under a different lux level.

gold and white. I don't see the blue or black

Blue and black. Still a pretty hideous dress though. I don't see any mileage in anyone wearing it, because if the thing which people remember about the dress is not knowing for sure what colour it is, then you're doing it wrong.

Having said that, looking at the official page it doesn't look too bad. Internet clothes shopping is a risky business that I've been stung by before, so still not sold. Nice lace pattern on it, I'll give it that. 

You can tell by the objects to the right that each of those 3 pictures is the same with different lighting effects.  The picture in the OP is the middle picture.  Not sure how someone can see two different colors after seeing the picture, your mind must be playing tricks on you.

I can only see white and gold, no matter how harder I try, i don´t see blue and black anywhere.

Blue and gold. No other opinions or options needed. Took me 20 minutes to convince colleagues, though :)

seen both color types In different pictures. on facebook it was white/gold on op's its black/blue

Really no blue? Interesting...
