Initially I saw white & gold, and I kinda still see it that way. The assumption I noticed I had is that there is a window behind, which gives out a bluer shade of light than the store lights. On closer inspection, the blue tint doesn't quite match that assumption and that the dress must have a blue tint. I cannot unsee the gold shade, but thinking about it, it could very well be the store lights that cast the yellowish tint.
