I applied @n-peugnet advice and this works at my locale
latex_engine = 'lualatex'
latex_theme = 'howto'
latex_elements = {
"preamble": r"""
\directlua {
luaotfload.add_fallback("emoji",
{
"[TwemojiMozilla.ttf]:mode=harf;",
"[DejaVuSans.ttf]:mode=harf;",
}
)
}
\setmainfont{LatinModernRoman}[RawFeature={fallback=emoji},SmallCapsFont={* Caps}]
\setsansfont{LatinModernSans}[RawFeature={fallback=emoji}]
\setmonofont{DejaVuSansMono}[RawFeature={fallback=emoji},Scale=0.8]
""",
}
produces

I changed the type of this ticket to question because it does not seem to be related to a bug in Sphinx LaTeX support, except if one considers support for color emojis should be built-in, on which topic I don't have myself any strong opinion!

Using #12195 n-peugnet solution I go it (almost) working:
Change latex_elements in conf.py:
latex_elements = {"preamble": r"""
\directlua{ luaotfload.add_fallback("emoji", {"[TwemojiMozilla.ttf]:mode=harf"}) }
\setmainfont{LatinModernRoman}[RawFeature={fallback=emoji},SmallCapsFont={* Caps}]
\setsansfont{LatinModernSans}[RawFeature={fallback=emoji}]
\setmonofont{DejaVuSansMono}[RawFeature={fallback=emoji},Scale=0.8]
""" }
content, titles and code Colors emoji in PDF !
But ⣿ character missing, in content, code and titles ;(
$ grep Missi _build/latex/test_emoj.log
Missing character: There is no ⣿ (U+28FF) in font LatinModernRoman/B:mode=harf
Missing character: There is no ⣿ (U+28FF) in font LatinModernSans/B:mode=harf;
Missing character: There is no ⣿ (U+28FF) in font LatinModernRoman:mode=harf;s
Missing character: There is no ⣿ (U+28FF) in font DejaVuSansMono:mode=harf;scr
Missing character: There is no ⣿ (U+28FF) in font DejaVuSansMono:mode=harf;scr
Missing character: There is no ⣿ (U+28FF) in font DejaVuSansMono:mode=harf;scr
Missing character: There is no ⣿ (U+28FF) in font DejaVuSansMono:mode=harf;scr
$
How to have both hammer 🔨 and ⣿ (U+28FF) in the final PDF ?

You can provide a chain of fallback fonts in add_fallback. I didn't test myself but check the description of the function in luaotfload's documentation.
I guess you could add some Noto symbolic font (or Symbola) to the chain.

As I stumbled across this issue:
For other unicode characters like greek letters, it is enough to add \usepackage{commonunicode} to the preamble in the latex_elements config in the sphinx conf.py:
latex_elements = {
'preamble': r"""
\usepackage{commonunicode}
""",
}from sphinx.
