This isn't another story about that dress, or at least, not really.
It's about the way that humans see the world, and how until we have a way to describe something, even something so fundamental as a color, we may not even notice that it's there.
Until relatively recently in human history, "blue" didn't exist, not in the way we think of it.
As the delightful Radiolab episode "Colors" describes, ancient languages didn't have a word for blue — not Greek, not Chinese, not Japanese, not Hebrew. And without a word for the color, there's evidence that they may not have seen it at all.
Every language first had a word for black and for white, or dark and light. The next word for a color to come into existence — in every language studied around the world — was red, the color of blood and wine.
After red, historically, yellow appears, and later, green (though in a couple of languages, yellow and green switch places). The last of these colors to appear in every language is blue.
The only ancient culture to develop a word for blue was the Egyptians — and as it happens, they were also the only culture that had a way to produce a blue dye.
If you think about it, blue doesn't appear much in nature — there are almost no blue animals, blue eyes are rare, and blue flowers are mostly human creations. There is, of course, the sky, but is that really blue? As we've seen from Geiger's work, even scriptures that contemplate the heavens continuously still don't necessarily see it as "blue."
