Oh, it's the whole trick of the eye thing. I get it now, no wonder people are seeing gold when it's obviously not gold even if it was a yellowy colour. Not white either, surely people wouldn't see White white, but like a blue white, as the shade of the dress alone isn't lighter than it's surrounding. Same effect as this right? |
Yes, as RuRo says it happens to colors as well.
The gold/yellow/black etc thing could be a bit trickier. That part of the dress seems to be transparent, so the color of what there's under it can have an impact, so it's possible that the dress can be black despite the RBY value in the pic for that part of the dress not being black. Furthermore color isn't an intrinsic property of objects and changes with lighting. There seems to be artificial lighting in that pic, which can* make things look redder than they actually would look under sunlight.
* Depends of wavelength (example of this: a light bulb).
