There's a fascinating podcast (with transcript) at https://www.wnycstudios.org/podcasts/radiolab/segments/21121... about linguistic studies that show blue to be the last color named in virtually all languages. There was no blue in the Odyssey or the Iliad because the Greeks didn't have a word for it yet. It appeared a few centuries later. Same in other languages around the world. Centuries of writing with no reference to the color blue, and then one day it appears. The podcast is a good listen.
