What color is this dress?

I see only the blue and black. Colour perception can be weird sometimes.

It appears that the dress is this one. (Obviously I didn't find this myself; it is circulating on the internet.) Look at the lace pattern and the sequence of stripes; they match exactly. There seems to some sort of separate shawl over the shoulders in the disputed photo. The dress does come in some other colours but all of them have black stripes; there is no white and gold version available.

To me this is totally unsurprising; the photo is obviously of a blue and black dress. But I would be interested to see a serious scientific optical explanation of what's going on.

However, we can still look at the cross-tabs and we see there is a MASSIVE age gap.

So, is the whole "white and gold" phenomenon caused by people who stare at screens all day and never go outside to see how light and colour work in the real world?
