GHCi in colour

This page documents efforts to colourise GHCi output.
Or a type error:
Output like this would be the result of running, for example:

2.1 Using HsColour
An existing tool, HsColour, could be modified to operate interactively. In fact, HsColour is already interactive, and with a small patch added on 2006-12-14 to control ouput buffering better, this works relatively nicely:
ghci 2>&1 | HsColour -tty
Neil Mitchell has a prototype gui haskell wrapper, based on gtk. Does this contain a reasonable ghci wrapper we could steal?
If you have an idea of how to do this nicely, add your proposal here.
