Please just don't. This is not the web.

Color usage in the terminal should be largely semantic, not stylistic.

Speaking for the group of people I know and work with, we don't want a "consistent experience" and hate TUIs that try to manhandle the color palette. Use color sparingly and with intention. Respect that different people have different settings.

First, I make third-party Vim colorschemes, not app. People install my colorschemes because they like the colors, not because I'm a monster with a gun pointed at their face. No one is harmed. No one is forced to do anything they don't want.

Outside of my text editor, where colors matter a lot to me for syntax highlighting, I'm definitely in the NO_COLORS camp (and in the NO_EMOJI camp, nowadays).

I wholeheartedly agree but 0-15 sadly have zero inherent semantics, which is the single reason behind every terminal colors-related drama since forever: developer choses 9 to highlight an error message because it is generally a bright red by default --> user sets 9 to whatever makes sense to them --> error message is illegible.
