Who has a purple lightsaber?  While blue, red, and green lightsaber crystals are the most common colors in the Star Wars universe, purple is less often seen, and these exceedingly rare crystals were used by few duelists throughout history.  Jedi are most commonly seen with the purple lightsaber. However, purple crystals are unique in the sense that they share an affiliation to both the light and the dark side. With a mixture of red and blue to produce the purple hue, this correlation makes more sense.  The Jedi with a purple lightsaber typically have a stronger alignment with the light side, but have been known to journey off into the darkness only to later return to the light.
