> Unlike the "default" patch, I quite do not see the point of the example(s). Yeah. This "reset" one was developed mainly as a hedge in case there were concerns about the "default" one. You're correct that the "default" one provides a finer-grained capability, and if we had to choose, I'd go with that. However, the two are mutually compatible (no conflicts, even) and complementary. This "reset" approach seemed easier to go through since it just generalizes the treatment of the existing "reset" capability without introducing any new names or even SGR sequence numbers. (The immediate goal of was to have some way to control from a color whether to inherit or remove an existing background). > Instead of saying "reset green", can't we already say "set bg to default, and set fg to green", thanks to the other one? Yes-ish, however, "default" is just a color name: and like other colors, it doesn't imply any attribute (bold etc) resets. Like, if you turn on bold, and then change the color to red, you'll get bold red. If you then change the foreground back to default, you'll have bold whatever. Instead, with "default", to avoid inheriting you could write: green default no-bold no-dim no-italic no-ul no-blink no-reverse no-strike resulting in an ANSI sequence like: `\e[22;23;24;25;27;29;32;49m` It's just a mouthful. `reset green` results in `\e[;32m`, which does functionally the same thing. It's just the combination of "reset everything" (``\e[m` or equivalently \e[0m`) followed by a color (`\e[32m`). I considered calling "reset" something like "only" since that reads more clearly to me, but I also felt it was not worth the cuteness when "reset" already existed and was defined consistently. > Or does "default" do too little to deserve a name that implies "go back to default", e.g. by not defeating the 'blink' attribute that was set earlier? I agree that "default" feels ambiguous. Within the current positional-name format vs. e.g. "fg=green bg=default bold=on", I had a lot of trouble thinking of a name that wouldn't be. However, "default" is the same word as in the ANSI spec, used in console_codes(4) (see heading "ECMA-48 Select Graphic Rendition here: https://man7.org/linux/man-pages/man4/console_codes.4.html) and ncurses (https://man7.org/linux/man-pages/man3/default_colors.3x.html). I also explored a few terminals' settings to see if there was a better name: usually they'll just refer to it unhelpfully as "foreground" or "background", but when they're otherwise named it's usually like "DefaultForeground". Other names I'd considered had their own problems: "unset" could be confusing alongside the existing "reset", "clear" could be confusing as a foreground or in the context of translucent terms, "no-color" is usually just untrue, and "normal" is (very confusingly, IMO) already special-cased as a no-op word.
