The different colors of Star Wars lightsabers all have a very special meaning. We take stock.
The Star Wars universe is full of details and mysteries that fans have fun unpacking and interpreting. One of the most notable is the color of the lightsabers, which vary significantly depending on the characters using them. They thus have their own meaning which makes it possible to better understand the symbols of the saga and the protagonists of the franchise.
Blue lightsabers, which are most common among Jedi, represent loyalty, courage, protection. No wonder mentors or heroes like Obi-Wan Kenobi, Luke Skywalker, Anakin Skywalker or Rey carry it. Green lightsabers are used by Jedi Consulars, particularly Force-sensitive, who favored dialogue and mediation over violence. It represents experience and maturity, qualities that characterize Qui-Gon Jinn, Master Yoda, or Luke Skywalker in particular.
The red lightsabers come in opposition to the blue ones. They represent hatred, lust for power and anger, and more generally the dark side of the Force in which the antagonists and the Sith, like Darth Vader, Kylo Ren or Darth Maul and Darth Sidious, have sunk. The purple lightsaber is rarer, and for good reason: only Mace Windu wields it. While it represents the balance between the light (blue saber) and dark (red saber) side of the Force, it had no special meaning at the time of its creation: actor Samuel L. Jackson intended a lightsaber that stands out from the others and wears his favorite color, purple.
Video game enthusiasts may have experienced yellow lightsabers in Jedi Power Battles and Knights of the Old Republic. They were originally created to provide more customization options for players. Later Star Wars lore clarified that these sabers were worn by Jedi Sentinels and Jedi Temple Guards, to symbolize the balance between wisdom and strength. In film, the yellow lightsaber appears in The Rise of Skywalker, to show that Rey is starting a new Jedi order.
There are also lightsabers of other colors, but much rarer in the Star Wars Extended Universe. White Lightsabers, the most notable of which is wielded by Ahsoka Tano. This one, representing purity and neutrality, was created to symbolize the fact that this character did not belong to the Jedi or the Sith. The dark lightsaber, the exact meaning of which has never been developed, is used in The Mandalorian series by Tarre Visla. There are also orange lightsabers, the meaning of which is also not (yet) developed.
