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...
