Hmm, I suspect that almost everyone who works in the terminal has never done this. I don’t really care what the colors look like, beyond choosing between whatever built in themes my terminal has. Is this really the minority experience?
I'm pretty sure the word "custom" refers to the act of choosing among builtin themes in the terminal. Some terminals like ghostty have hundreds builtin.
