I'm on this side of those wishing to leave the lightsaber colors alone, unless there's a really good reason for it (for instance, changing Dooku's color so he's no longer a Sith). However, let's keep in mind two things:
1) This is the Prequel Radical Redux Ideas Thread
2) Any ideas that are put into play will be done thru a fanedit. As such, if you think something is a bad idea, say so, then let it go. You don't have to watch the edit.
