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.
Green lightsabers have been wielded by a number of famous Jedi including Master Yoda, Qui-Gon Jinn, and Luke Skywalker. In Return of the Jedi, Luke's lightsaber color switched from blue to green, possibly representing his development as a skilled Jedi warrior.
Blue indicated a Jedi Guardian, a Jedi who used the Force on a more physical level. Green indicated a Jedi Consular, a Jedi who preferred to reflect on the mysteries of the Force and fight the dark side at its heart.
His inclusion in The Mandalorian and The Book of Boba Fett also gave fans a chance to see Luke Skywalker wield the green lightsaber properly in the Disney era after the weapon was largely missing (bar flashbacks) from the Star Wars sequel trilogy.
Indeed, in Star Wars, Episode V: The Empire Strikes Back, Luke Skywalker duels his father Darth Vader on Bespin and gets his hand cut off by the latter. The saber is then recovered by the Dark Lord of the Sith. Disarmed, the Jedi Luke decided to create a green lightsaber.
Leia Organa's lightsaber was a blue-bladed lightsaber powered by a kyber crystal in the core of the hilt. It was silver and copper in color and featured mother-of-pearl inlays. Organa's weapon was considered a work of art, having an elegant symmetry with silver and gold hues that evoke to her upbringing on Alderaan.
Luke hid his lightsaber inside R2-D2's dome during his mission to rescue Han Solo from Jabba the Hutt, and surrendered the weapon to Darth Vader as part of his effort to reawaken the spirit of Anakin Skywalker.
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.
Subsequently, Yoda didn't want to wield another lightsaber. However, he kept another lightsaber in a box in his hut in 3 ABY. After Yoda's death in 4 ABY, that lightsaber ended up in the possession of Yoda's last Jedi apprentice, Luke Skywalker.
Anakin Skywalker carried this blue-bladed Jedi weapon throughout the Clone Wars. After dueling his former apprentice on Mustafar, Obi-Wan Kenobi took Anakin's lightsaber and kept it on Tatooine for nearly two decades.
This can be seen in the novel starwars.wikia.com/wiki/Rogue_Planet. It's because of his mastery of sorsue (sorry for my bad spelling.) Well if you want the ACTUAL reason it because in the original 3 films the Green Light Sabre didn't exist until after Obi Wans death.
Black lightsabers are extremely rare in the Star Wars universe, and only a few have been seen on screen. These lightsabers are typically associated with the Dark Side of the Force and wielded by Sith or Dark Jedi. The most well-known black lightsaber is the Darksaber, which was created by the first Mandalorian Jedi.
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.
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.
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. For years it was kept safe at the Jedi Temple.
2) Who is the only non Jedi in the original Star Wars trilogy to use a lightsaber? Han Solo uses Luke's lightsaber to cut open the tauntaun's belly in The Empire Strikes Back.
Though he saw Anakin's potential, Yoda could not ignore the danger inherent in Anakin's unrestrained emotional attachments. To teach Anakin responsibility, Yoda assigned Skywalker a Padawan learner: Ahsoka Tano. Yoda knew there would come a time when Anakin had to let go of Ahsoka.
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.
Star Wars Legends Who Wield a Purple Lightsaber
Daughter to legacy characters Han Solo and Princess Leia Organa Solo, she had her father's aptitude for mechanics and her mother's force sensitivity. Not only was she a Jedi Master, but also a rogue squadron pilot and a member of the Jedi counsel.
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.
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%.
The blue lightsaber meaning, at its very core, is to serve as a protector and gatekeeper, promising safety from the evil that that tortures harmonious creatures of the galaxy. No matter how far, a Jedi Guardian is determined to seek out evil and extinguish its hold on the peaceful beings that the Sith torment.
Kyber crystals are rare gems that possess a natural connection to the force. Kyber crystals have to be mined from deep within the ground, and so they are only found on specific worlds like Ilum, Exegol, Jedha, Lothal, and Utapau among others.
Purple is a blend of red and blue. In Star Wars, traditionally blue lightsabers were used by the Jedi, the heroes of the galaxy and red lightsabers were used by the Sith, the villains. The shading purple speaks to moral uncertainty, reconstruction, and recovery.
