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.

It's not 'defects' :nono:

Lots of people thought, as you evidently do, that their own experience must be correct and everyone else must be defective. :naughty:
