The most notable feature of Star Wars is lightsabers. The films established this sci-fi weapon as an important pop culture product. The colors of the lightsabers also have their own meanings. What colors exist and what they mean, you can find out here.
How are lightsabers constructed in Star Wars? Every Jedi or Sith has their own lightsaber, which consists of several components. The most important feature is a kyber crystal, as it determines the color. However, Force users cannot simply choose this crystal. The crystal connects with the user.
Before Disney, the crystal was supposed to reflect the experience and skill of the user. Nowadays, this has become a bit vaguer, and the crystal tends to align more with the core of the person who wields it.
In this list, we ignore the fact that various games related to Star Wars allow players to customize lightsaber colors at will.
By the way, the famous red color is not naturally occurring. The Sith have to corrupt a crystal to make their trademark color. This method was shown in The Acolyte: The Acolyte: The new Star Wars series showcases one of the most legendary lightsaber techniques of the Sith for the first time on screen
Blue Lightsabers
Known users: Obi-Wan Kenobi, Anakin Skywalker, Rey, Luke Skywalker
What does the blue color mean? The blue color represents courage and justice. It also shows a spiritual alignment along with the crystal. The blue color is supposed to represent mastery of the Force and in combat as well. Users of blue lightsabers were also regarded as protectors of the Jedi.
Originally, George Lucas even planned to have only blue and red lightsabers, as they were to symbolize the fixed opposites. (via Padawan Outpost)
Green Lightsabers
Known users: Yoda, Luke Skywalker, Qui-Gon Jinn, Sol
What does the green color mean? Green lightsabers symbolize a philosophical approach. This is evident in the famous users like Yoda or Qui-Gon Jinn. Also, Luke switched from a blue to a green lightsaber after training with Yoda.
Users of green lightsabers have a different approach to the Force. They studied the lore and are valued advisors on important matters. Nonetheless, they can also be dangerous in combat as they have a special connection to the Force.
