Currently, there is an existing tool, HsColour:

Here's a mockup (the result of dumping ghci's output through HsColour):
Have you tried just piping ghci through HsColour interactively? ghci 2>&1 | HsColour -tty It works surprisingly well. I just pushed a patch that ensures stdout is unbuffered in interactive mode, so you can see the prompt before you type something, rather than after completing a line. Colouring is still a little bit jumpy, because HsColour has to consume one whole lexeme before colouring it, but the result is not bad. It does tend to mess with readline a bit though...
