I'll play devil's advocate on this one.

You can communicate to the toplevel `make' invocation, in the same
manner as the job server, the number of targets considered and the
number of sub-makes invoked.  That won't give you a percentage, of
course, as neither needs to be constant over two `make' invocations
nor with different MAKECMDGOALS.  But these two numbers can give a
rough estimate on the progress.

Yes; and in fact, Automake 1.11 has the option 'color-tests' which can
cause the output of 'make check' to be colorized, if you use the builtin
test driver (i.e., TESTS = ...).

For normal build rules, I would go this way only with another option,
and only if there was a useful and easy semantics for this colorization.

For highlighting compiler warnings, I'd just try out the 'silent-rules'
Automake option (Linux kernel-style build output).

Of course; and in fact, editors have been doing this task very well for
years already.  But now that we're already on our way to the dark side,
see above, it's even more difficult to convince users that it's the
wrong path.  ;-)
