The dress is white and gold, or blue and black?

Its proven that its blue and black

gold and whitish blueish 💙💛

I love how people honestly think its white and gold. I can see both color combinations, but I know that it's actually black and blue.

still, I see what I see!

even if I know it's wrong

What does "it's actually blue and black" even mean? Like color doesn't actually exist as a concrete thing it's subjective from person the person, species to species.
