For the record, of course, the dress is probably not blue, nor black, nor gold, nor white. Those are just the colors we perceive being reflected back at us.

Which I'm slightly surprised ngt didn't bring up.

Now that's a bit pedantic of you. Without accepting that as a basic part of their meaning, then the words for colors have no meaning left.

But if we truly want to know what color a thing is, how can we? 10% of people are color-blind, other species can see frequencies that we cannot see. At any rate, I agree with you, I just brought it up cuz it seemed relevant.

We watched a Brain Games about color perception this weekend, my daughters:

Youngest: Mommy, they said a stop sign wasn't red. But they're wrong.

Oldest: Ugh! We just see what colors are reflected, we don't really know what color it is!

One of my favourites.

It is the only organism known to simultaneously detect the four linear and two circular polarization components required for Stokes parameters, which yield a full description of polarization. It is thus believed to have optimal polarization vision.

I like how lots of flowers have ultraviolet landing strips on their petals that only bees can see.
