To do something similar using a graphical diff program, I have a
script which wraps round the other RCS tools to achieve what I what.
Since there is a 'colordiff' program out there, you could do the same.

My script is below - the graphical diff is 'meld', so just replace
that with 'colordiff' and you'll be a good bit of the way there...

Not polished, not perfect, but works for me.....
