 Luke Skywalker's new lightsaber in "Return of the Jedi" was colored blue during the initial editing of the film, and appears so in both an early movie trailer and the official theatrical posters.However, it was changed to green in the film's final edit after initial viewings by the filmmakers, who felt that it would better stand out against the blue sky of Tatooine in outdoor scenes, and this color change is also reflected in the film's re-release posters.Mace Windu's purple-bladed lightsaber, as first seen in "Attack of the Clones", was requested by the actor Samuel L. Jackson for two reasons; purple is his favorite color and that the purple blade is one way to make his character stand out among other Jedi.
