On the dress (which was shown a few years ago), I see it as black and blue. IIRC, one of the fashion mags that took a photo of this same dress evidently seriously over-exposed the photo, so that the blue looked white and the black looked gold. Lots of people then thought that their colour vision must be awry! The only thng that was awry was the exposure.
Spectacular way to miss the point David.
The point is not that " the blue looked white and the black looked gold" but that the colours were ambiguous and some people perceived it very clearly one way and others saw it the other way. The photo itself was not objectively either one nor the other. Many many people could not believe that anyone saw it the other way to the way they saw it.
