It might be worth noting a few things we discussed. In particular:

  These can generally already be accessed as colors 8-15 of 256-color
  mode. But some terminals support these 16-color versions without
  supporting 256-color mode. And they're fewer bytes, which can make the
  output slightly more efficient.

I think we'd need a documentation change, too. These are discussed in
Documentation/config.txt (search for the "color::" heading).

This drops the "+" version. I think we _could_ do both, but just having
"bright" is probably fine.

Having to repeat "6" isn't ideal, but we sadly don't have a
case-insensitive version of skip_prefix(). We could do:

  static const char bright[] = "bright";
  ...

  if (istarts_with(name, bright)) {
	color_offset = COLOR_FOREGROUND_BRIGHT_ANSI;
	name += strlen(bright);
	len -= strlen(bright);
  }

but I'm not sure if it's worth it.

The 0/1 return here is unusual for our codebase. We'd usually return "0"
for success and "-1" for failure.

Otherwise, the patch looks good.
