For me, I get why the part that I'm seeing as white is confusing. Straight out of the photo it looks periwinkle. But I think it was taken on a crappy camera and that's just a shadow, so I see it as white. I really don't see how someone could see it as straight up blue though.The gold/brown part, on the other hand, is crystal clear. I really don't understand why anyone would see it as black.
Here's an article on this phenomena:https://www.wired.com/2015/02/science-one-agrees-color-dress/From the three photos I don't even see the lightest one as white-gold, but light blue and bronze.

Ok, maybe this difference explains why we perceive Bach's music so differently?
I use my ears. If you're using your eyes, that certainly explains a lot.
I think it is a contextual white balance issue. We are seeing a photo of reflected light off of an object. Our brains are trying to decipher the what the prevailing light conditions were when the photo was taken in order to determine an internal white balance level so that we may interpret the color data.
