Mace Windu's lightsaber in the Star Wars universe had a unique color. Unlike most lightsabers, which are either blue or green for Jedi, Mace Windu's lightsaber had a purple blade. This distinctive color was specifically chosen to reflect his character's unique personality and fighting style. Samuel L. Jackson, the actor who portrayed Mace Windu, requested the purple lightsaber as a way to make his character stand out in battle scenes.
