AFAICT Unicode says that those codepoints have Emoji_Presentation=No,
which means that applications should prefer a "text presentation",
i.e. in Emacs, a non-color font, *unless* you append U+FE0F VARIATION
SELECTOR-16 to these characters.

See https://unicode.org/reports/tr51/#Emoji_Presentation for reference.

Just C-x 8 RET FE0F after those characters, and Emacs (starting with
version 28) will display them with a color font as you expect.

Or use Emacs 29's emoji selection commands, e.g. C-x 8 e s warn RET,
which will automatically append U+FE0F if needed.
