I kind of liked that Mace had a purple saber — at least he had "some" character to him. They made green and blue too common and boring. I remember first seeing Luke with his green lightsaber in ROTJ, but now it seems less special as it once was. They should have had other Jedi carry different colored lightsabers just to change things up — maybe yellow, orange, or even pink for some of the babes. :p Well, anyway, I always imagined Yoda with a yellow one. I think it's odd that he himself being green would use green. :(
