Actually we do have a system; only staff members and members designated as having made specially important contributions to the wiki (AKA, Hall of Fame) can colours. Some mods/admins don't want colours, so to fix that we gave Mods a bold name, and Admins a underlined name (Which Zero refuses to use). Each mod or admin freely chooses their name colour, with a limit of two changes per month.

Zero, I only changed mine because it was starting to get stale for me. And Mudd, black and red, as I recall, are prohibited from being used as name colours, for obvious reasons.
