That's fine, and isn't a bug.  The buffer where you do this doesn't
support font-lock.

Well do
$ emacs f.pl f.html f.c etc. etc.
They are all black and white by default!

Not here, they aren't.  Does this happen with "emacs -Q"?

$ emacs -q -Q index.html etc.
All just black and white.
Have to do M-x font-lock-mode
so see any colors, here with Debian's 26.1.

Then I suggest that you take this up with the downstream Emacs package
maintainers for Debian, because Emacs built from sources here doesn't
have that problem.
