Colors are added at display time, so hooks will not help here.  Or at
least it isn't immediately clear to me how they could help.

I suggest to study how syntax highlighting works in Emacs, including
the JIT font-lock feature and its relation to the display engine.
Until you have a good understanding of how this stuff works, I don't
think you will be able to come with a design for hooks which external
tools could use for this purpose.
