Lightsaber colors in the Star Wars universe are often associated with different Jedi or Sith characters, but it's important to note that lightsaber colors can vary based on individual choices and personal crystal alignments. Here are some commonly known lightsaber colors and the characters associated with them:
1. Blue: Jedi Knights such as Anakin Skywalker, Obi-Wan Kenobi, and Luke Skywalker are known for using blue lightsabers. Rey, the main character in the sequel trilogy, also wields a blue lightsaber.
2. Green: Jedi Knights like Yoda, Qui-Gon Jinn, and Luke Skywalker (in Return of the Jedi) are known for using green lightsabers. Ahsoka Tano, a former Jedi Padawan, also uses a pair of green lightsabers.
3. Red: Sith Lords such as Darth Vader, Darth Sidious (Emperor Palpatine), and Darth Maul are known for using red lightsabers. The red color represents their affiliation with the dark side of the Force.
4. Purple: Mace Windu, a Jedi Master portrayed by Samuel L. Jackson in the prequel trilogy, wields a unique purple lightsaber.
5. Yellow: Jedi Temple Guards in the Star Wars animated series, particularly in Star Wars: The Clone Wars, use yellow lightsabers. In some instances, Jedi Sentinels may also be depicted with yellow lightsabers.
6. White: Ahsoka Tano wields white lightsabers after leaving the Jedi Order and becoming a "Gray Jedi" or "Force-user" in Star Wars Rebels.
7. Other colors: There are also lightsabers with less common colors. For example, in Star Wars: The Clone Wars, the Dark Saber possesses a black blade with a white outline, and in Star Wars: The Rise of Skywalker, Rey wields a yellow lightsaber at the end.
It's worth noting that lightsaber colors can have different interpretations or variations in various Star Wars media, so these associations may not cover every instance.
