Consider a file =foo.org= with the following content:
#+begin_src org :tangle foo.org
,#+begin_src emacs-lisp
(defun foo (a b c)
"A metasyntactic function that doesn't do much."
(interactive)
(message "foo"))
,#+end_src
#+end_src
I can export that to HTML and get a nicely colourized export like so:
#+begin_src sh :results output verbatim
/Applications/Emacs.app/Contents/MacOS/Emacs --file foo.org --eval '(progn (package-initialize) (org-html-export-to-html nil nil nil t) (kill-emacs))'
cat foo.html
#+end_src
#+RESULTS:
: <div class="org-src-container">
: <pre class="src src-emacs-lisp">(<span style="font-weight: bold;">defun</span> <span style="font-weight: bold;">foo</span> (a b c)
: <span style="font-style: italic;">"A metasyntactic function that doesn't do much."</span>
: (<span style="font-weight: bold;">interactive</span>)
: (message <span style="font-style: italic;">"foo"</span>))
: </pre>
: </div>
However, I can't run it like that because I'm trying to run it headless
on CirleCI, where neither DISPLAY nor TERM environment variables are
set. (Yes, I'm trying to automate my blog publishing.)
Adding a ~--batch~ flag to the command makes the command run on
CircleCI, but I get a less colourful (and less pleasing) result. The
markup appears to only use /italic/ and *bold* styles now.
#+begin_src sh :results output verbatim
/Applications/Emacs.app/Contents/MacOS/Emacs --batch --file foo.org --eval '(progn (package-initialize) (org-html-export-to-html nil nil nil t) (kill-emacs))'
cat foo.html
#+end_src
#+RESULTS:
: <div class="org-src-container">
: <pre class="src src-emacs-lisp">(<span style="font-weight: bold;">defun</span> <span style="font-weight: bold;">foo</span> (a b c)
: <span style="font-style: italic;">"A metasyntactic function that doesn't do much."</span>
: (<span style="font-weight: bold;">interactive</span>)
: (message <span style="font-style: italic;">"foo"</span>))
: </pre>
: </div>
Is there a way I can get the nicely coloured output while exporting in
~--batch~ mode?

PS: In reality I'm using Org's publishing setup, but it was easier to
create a minimal example using export than an ECM that involves having
to configure ~org-publish-project-alist~...

--batch skips your initialization file. You will have to provide a minimal
load file that does the initializations you need and then use -l to load it:
--8<---------------cut here---------------start------------->8---
emacs --batch -l my-init-file.el --file foo.org \
--eval '(progn (package-initialize) (org-html-export-to-html nil nil nil t) (kill-emacs))'
--8<---------------cut here---------------end--------------->8---

Thank you. I did have a separate init file, but at the time I hadn't
figured out what to put in it! (I simplified my ECM too much!) However,
I've since discovered the magic org-html-htmlize-output-type variable
that does what I need.
My apologies for wasting people's time. I should have spent a bit more
time searching the archives, and less time building an ECM to
demonstrate something documented not to work!
