A common tactic is to use grep twice: ps auxf | grep -v grep | grep blah That strips out all instances of grep from the results. Putting what you're searching for first is more efficient, but putting it last keeps the colorized output intact. LMP I often deal with that by using the search function in my terminal (usually konsole) to highlight the term I'm actually looking for.
