Technically, where sabers are concerned, it does. The whole idea behind the crystals is that the blue and green crystals come from Jedi-controlled territories, just as the red crystals are exclusive to Sith areas. (As to ship lasers....ssshhhh, continuity ^^) On the crystal area thing, there is no reason why there wouldn't be red crystals growing in the same caves as the red. And as when it comes to the red, most where actually synthesized, and the synthesizing process made them red.
