[Haskell] interpreter ouput in color

Hi all. I was wondering if some people miss the colored output of some applications, such like the IPython enhanced shell. I've been googling for similar options for Haskell but I found nothing. I feel that the type error messages, for example, would be a lot more readable (or at least quicker to read). Is there a way to write plugins for ghci to get this?, or do you people have some suggestion about what would be the easiest component to hack for applying colors? Thank you. Cheers, Walter
