Are there any guidelines or standards when referring to colors?
I am not asking about objective systems like RAL, Pantone, HTML or simply referring to a colors wavelength, but rather terms like blue, red or even terms like violet and petrol.
Lets say I am writing an article (a scientific one in my case, but I guess that should also apply to a news article or an advertisement) where I have to refer to a figure in a text.
You could think of various reasons to refer to the different bars: "Our product I ist much better than all our competitors!", "At point E there was a clear shift in attitudes", "Sample B exhibits a clear increase over sample A"…
But sometimes, it makes more sense to refer to a color, instead of an identifier, even though that can cause issues for people with color blindness and with the reproduction of said color.
But what kind of terms can I expect to be known by a general audience? What terms should I use for certain audiences? In a fashion context, there probably is a perfectly fitting name for each color in the sequential row (probably stuff like Ocean, Petrol, Jade and Obsidian), but for me, those are all green_ish_, which probably also brings in the guy vs girl issue. So sequential colors are probably a bad idea in a context where I have to refer to a single one, which probably also applies to diverging.
Qualitative seems like a much easier pick, especially when using colors that are agreed on, like red, blue, yellow or black, but after a certain amount of colors, I am running out of easy ones. And how do I address, lets say C then?
Purple? Violet? Greyish-pink? Amethyst? Eggplant? Purple-blue?
What guidelines or rules are there, for picking and addressing colors in such a situation?
