mhhh.... something like that would be good, but I don't know whether it isn't doable or it has never been considered, as also windows live today doesn't shows colours.
the biggest problem is that another add-on would be necessary (imho) to modify Windows Live Mail, as MP!L only "takes care" of WLM, but correct me if I'm wrong, as I'm not a beta tester of Windows Live Mail Desktop for the time being, so I know just a few things about it.
