What color will Rey's lightsaber be?

I gotta go with purple or even pink. Would be nice to legitimize the purple blade in the series and not have it be this sore thumb that it is associated only with the prequels. We'll see of course, but she'd look better with purple. Lord knows, I don't understand why Lucas had Mace be the only jedi with purple. It was just strange that he's the only one with his own lightsaber color... but it's hard to argue with Sam Jackson. He wanted purple. Lucas bowed to his wishes didn't he...
