The lightsaber's amethyst color was chosen by the actor portraying
Purple blades are exceedingly rare in the Star Wars universe; in fact, Windu is the only Jedi known to wield one, at least in current canon. As you undoubtedly know already, the Jedi almost always carry blue or green blades.
During the interview on "The Graham Norton Show," Jackson said he asked George Lucas, the creator of "Star Wars," for his fictional weapon to be purple so that he would be able to find himself in the battle scene in the second prequel movie, "Star Wars: Attack of the Clones."
The blade was also rare, in that it was purple. This color was acheived using an extremely rare crystal found on the planet Hurikane. The purple color was symbolic, indicating that the bearer had studied several forms of lightsaber combat, including delving into the dark techniques of the Sith.
In 58 BBY, a young Mace Windu was sent to Hurikane on a mission as a Padawan. In exchange for helping the stone-encrusted native species, Windu was given a handful of the rare amethyst Hurrikane crystals, which he used to create his unique electrum lightsaber.
The weapon had a kyber crystal at its heart, and emitted a yellow-colored plasma blade when ignited. The emitter matrix on Rey's weapon featured a rotating gear-like mechanism, which caused the emitter of the lightsaber to open up and allow the plasma blade through.
Unlike most of Revenge of the Sith's Jedi casualties, Star Wars never showed Mace's body, which means that a chance exists for him to have survived in some way. Although it didn't happen in Obi-Wan Kenobi as some fans hoped, Mace Windu could potentially turn up alive at some point in the future.
Star Wars: University study deduces that purple lightsabers are the strongest, red are the weakest. A recent university study determines the power levels of different lightsaber colors. Samuel L.
In the construction of a Sith lightsaber, individuals partook in a process known as bleeding. By ways of the Force, they would pour negative emotions such as rage, hate, fear and pain into kyber crystals. The process would result in the crystals gaining a distinctive crimson or red hue.
Some Jedi are explicitly shown using red lightsabers in Legends, however. This includes Adi Gallia, Even Piell, Depa Billaba, A'Sharad Hett, and even Luke Skywalker.
Only one person in canon wields a purple blade: the Jedi Council's Mace Windu. He uses it to decapitate the deadly bounty hunter Jango Fett in Attack of the Clones and to deflect Darth Sidious' Force Lightning with it -- disfiguring his face -- in Revenge of the Sith.
Mace Windu's lightsaber was the weapon wielded by the eponymous Jedi Master during his career. It was unique among Jedi as it produced an amethyst blade when activated, rather than the more common green or blue.
Trained as a Jedi Guardian, Windu was considered to be one of the best swordsmen in the history of the Jedi Order and had created the modern seventh form of lightsaber combat, Vaapad along with fellow Jedi Sora Bulq. He was the only practitioner of the form who did not fall to the dark side.
The cost of rebellion was a high one for the proud planet, turning the sight of Mandalorian armor into a rarity in the years following the fall of the Empire. In the first-season finale, Moff Gideon, former officer of the Empire, emerges from the wreckage of his fallen TIE fighter. And he wields the Darksaber...
Ahsoka Tano, the former Jedi Padawan who aided in the rebellion against the Galactic Empire, is acknowledged as the sole possessor of the white lightsaber.
After losing his father's lightsaber on Cloud City, Luke Skywalker constructed a replacement with a green plasma blade, its hilt similar to that of Obi-Wan Kenobi's weapon.
He tracked Jedi Master Kirak Infil'a to the river moon of Al'doleem and confronted him. Vader eventually killed the Jedi Master and retrieved his curved-hilt lightsaber. He headed to Mustafar, where he bled the saber's crystal, turning it from green to red.
A blue-bladed lightsaber belonged to the Sith Master Darth Sidious after his resurrection on Byss.
Etymology. From the Star Wars universe, where it is used as a title for Sith Lords. Blend of dark + death (the derivation from Dark Lord of the Sith is a later development).
While there are many one-of-a-kind lightsabers in the Star Wars universe, there is only one with the history and legend of the Darksaber, which was created by the first Mandalorian Jedi named Tarre Vizsla.
Red lightsabers are the weakest, according to a Star Wars study conducted at the University of Leicester regarding lightsaber colors. Decades of Star Wars lore has dictated that the red lightsabers favored by The Sith offered greater offensive capabilities than the softer colors favored by The Jedi.
Billaba became Windu's Padawan and trained under the Jedi Master in the ways of the Force. During her training, Windu allowed her to study Form VII variant known as Vaapad. She eventually became a Jedi Knight, renowned for her skills with a lightsaber and favored Form III when teaching other Jedi.
As Anakin's powers grew, Mace Windu's respect for Anakin grew, but his trust never did.
Mace Windu and Sheev Palpatine
But this rivalry was frustrating for many reasons. In true Samuel L. Jackson form, Mace Windu's character was never timid with his skepticism or disapprovals when it came to both the Senate and Anakin becoming a Jedi.
