Earlier quoted context omitted.
It’s “Fuchsia” with a “chs” not a “sch”. Where do you get your information that it’s dead?
As Randall Munroe pointed out in https://blog.xkcd.com/2010/05/03/color-survey-results/ , almost nobody knows how to spell "fuchsia" correctly. I only remember it by the mnemonic of it's fuck, but with an s.
It'll still be just as weird. But "chs" is just nonsensical. The idea that it would sound like "sh" is baffling. I mean, I know this is English spelling which is not known for its regularity, but this is just too much.
