I love all your color analysis. (Sadly I don't think my laptop monitor is up to displaying the nuances. Through intermittant work-from-home/work-from-work, I recently learned that my computer monitor at work shows colors in some of our spreadsheets very differently… which makes me worry that all the icons I've created may be slightly off.)

Color names are at their most frustrating when the marketing people get involved (so clothing catalogs and home decor). They'll outright mislabel things or give them entirely unhelpful names like (this is an actual example of a paint chip in a hardware store) "Miami Sunset". I honestly don't even remember what color that was; I just remember being annoyed by it. Orange? Yellow? Pink?

Artist's paints are pretty consistently labeled at least. (So you can order a tube of "sap green" without even looking at a sample and be pretty confident of what you'll get) Of course, that still doesn't give you all the colors, because artist's paints are meant to be mixed. Many brands don't even sell many shades of green, since green can be created so easily with yellow and blue. (Look at how many different shades of yellow or blue you can buy of these paints and how few shades of green are for sale: Winsor Newton color chart)

I always find it fascinating that people recognize "pink" as a distinct color from "red" but cannot make a distinction between a pastel pea green and a deep forest green. I think it really just comes down to the words. (I'm honestly dreading the blue-vs-indigo debate that's about to rage.)
