Purple lightsabers are very uncommon. In current canon, there is only one known instance of one, that being the lightsaber of Mace Windu. There was a legends story of how he acquired a purple crystal told in a comic, but that is no longer canon.
Purple lightsabers are among the most mysterious color lightsabers known in Star Wars. They were carried far less often than their green, red, yellow, and blue counterparts. While the association of these other colors is widely known, the purple lightsaber has a far less concrete history or origins.
Mace Windu may be the best-known Jedi to wield a purple lightsaber, but there have actually been several others to do so in Star Wars canon. Mace Windu isn't the only Jedi in Star Wars to wield a purple lightsaber.
Without a doubt, the most notable Jedi with a purple saber is Mace Windu, portrayed in the prequel trilogy by Samuel L. Jackson. Audiences first got a glimpse of the unusual blade in Episode II: Attack of the Clones, making Windu the coolest Jedi in one cinematic moment.
However, in Star Wars Legends, it indicates moral ambiguity, uncertainty, and reconstruction, as purple is a combination of red and blue. The purple lightsaber represents that its user shows an affinity with both the light and dark sides of the Force.
A crystal embodies the Jedi as the heart of the lightsaber, and pure kyber has no color until it's bonded to the Force user. This process likely resulted in Rey Skywalker's lightsaber being yellow.
While blue, red, and green lightsaber crystals are the most common colors in the Star Wars universe, purple lightsabers are less often seen, and these exceedingly rare crystals were used by few duelists throughout history.
Purple sabers indicate that the Jedi holding them fights with an aggressive style and understands both the light and dark sides of the force.
What is the rarest lightsaber color? The rarest lightsaber color is black and is known as a Darksaber. Tarre Vizsla created it – the first Mandalorian ever inducted into the Jedi order.
A pink lightsaber is essentially created by a purple kyber crystal, which is extremely rare to find. Luke Skywalker's lightsaber was originally pink in the original Star Wars comics. Obi-Wan Kenobi and Darth Vader both used pink lightsabers in their war against each other.
Yoda's lightsaber was smaller than a standard Jedi lightsaber, befitting his shorter stature. But its green plasma blade was every bit as deadly in combat.
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.
Purple itself is considered the most powerful lightsaber color in the Star Wars galaxy. Very few Jedi have ever wielded a lightsaber of this color. The only two people known to have wielded a purple lightsaber are Mace Windu and Darth Revan in the past.
Master Yoda has risen above all others to claim the top spot as the most powerful Jedi of all time and the true chosen one according to IGN's audience. He won pretty handily as well, as he was victorious in 89,756 of his 95,243 battles and had a win percentage of 94.2%.
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.
The Sith apprentice Darth Maul wielded a double-bladed lightsaber made by joining two hilts together end-to-end. Maul's dexterity and extensive training allowed him to use his weapon as a single-bladed saber, or to activate both crimson blades and fight multiple opponents at once.
An ancient lightsaber that serves as a powerful symbol of leadership to the Mandalorians, the Darksaber is a unique weapon with a black-energy blade lined with a crackling white edge.
Leia's lightsaber was a blue-bladed lightsaber used by Princess Leia Organa during her time as a Jedi Padawan training under her brother Jedi Knight Luke Skywalker.
Encased in a distinctive silver-and-copper hilt, Leia's lightsaber used a naturally-occurring blue kyber crystal, much like Luke's original saber that he had inherited from his father by way of Obi-Wan Kenobi.
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.
Arguably, some of the rarest types of Jedi were the so-called Iron Knights. These are members of the Shards species - crystals with a brain of their own. They were Force-sensitive and all trained under the tutelage of Jedi Master Aqinos. The Shards had droid bodies, similar to that of General Grievous.
