The colors are in fact light blue and charcoal gray. So the dress as shown in the picture is neither blue and black nor white and gold (I see white and gold). It's obviously something to do with the lighting or whatever but I just thought it was interesting that even though I see it as white and gold (unless I tilt my screen then I can see the blue and black) when I checked them in Photoshop they came out as light blue and gray.
