Lightsaber Colors - Two Sides of the Coin
Adam Rifkin stashed this in Star Wars!
There are way more colored lightsabers than I realized: http://starwars.wikia.com/wiki/Lightsaber_crystal
Did you know Samuel L. Jackson only accepted the part on the condition that he could have a purple lightsabre? True story.
So serioysly, No Purple in the image above?!
