Oh boy.
Anyway, I meant the multiple colors in the PT doesn't make any sense because, if you could make your lightsaber any color, why would the colors be 50% blue and 50% green with one purple and nothing else? And why, then, would all the Sith have red? It makes more sense to me if the Jedi have a unified lightsaber color (blue) which would also compliment the fact that the Sith lightsabers are uniform as well.
