I've liked the green from the start since I was always a proponent of keeping the old purple names for the reason that they didn't conflict with staff colours so much, since posts from site administrators are generally few and in the official sections, where as moderators are everywhere and tend to be active members in normal fashion. Having two blue usergroups was... not really too confusing, but there was no need for it when the previous colour was better differentiated. So, with assistant administrators gone and supporters green, it's better than ever, really.
