I don't necessarily care about the colors of lightsabers themselves, but I'm tired of all bad guys having red lightsabers, and especially tired of them all being named "Darth", I don't know what the EU says, but in Star Wars Darth just seemed like Vader's first name, but now it's an official bad guy title. I'm just glad the prequels never directly commented on the red lightsaber, because i remember in a behind the scenes interview for Ep. II Sam Jackson was chatting with Lucas about lightsaber colors and George said, "Well, good guys are green and blue, and bad guys are red..."
He should pay the price for his lack of vision.
