Luke Skywalker's lightsaber was changed from blue to green when they were filming because it was difficult to see. This became apparent during act one of Return of the Jedi when the battle on Jabba the Hutt's sail barge was shot during the day. The blue lightsaber blended in with the clear blue sky.
In the original 1982 teaser trailer for Return of the Jedi, the color of the lightsaber was blue. The decision to change the color of the lightsaber from blue to green was made to make Luke's blade contrast with the blue sky of Tatooine and make it more visible during the skirmish at Carkoon.
Luke Skywalker used to wield a green lightsaber before declaring himself a Jedi, so he nearly killed his father. After deciding to stop using the green lightsaber, he finally chose to put it away.
Many believe he destroyed it after sinking the X-Wing on Ahch-To as he denounced the force, and that the crystal he wears around his neck is actually the Kyber crystal from this lightsaber. This will probably be explored over the next couple of years as Star Wars 9 nears completion.
After defeating her grandfather, Emperor Palpatine, and ending the Sith threat (at least for now), Rey journeys to Tatooine. There, outside Luke's childhood home, she buries his and Leia's lightsabers, before igniting her own, crafted from the staff we first saw her wield on Jakku.
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.
It's possible that Rey adopted the yellow-bladed lightsaber (or perhaps the kyber crystal conjured a yellow blade based on the changes within its wielder) in honor of those emotionally detached sentinels tasked with guarding the Jedi Order.
After dueling his former apprentice on Mustafar, Obi-Wan Kenobi took Anakin's lightsaber and kept it on Tatooine for nearly two decades. He gave it to Luke Skywalker, who lost it when Darth Vader struck off his son's hand in Cloud City.
After Yoda's death in 4 ABY, the lightsaber with its accompanying storage box ended up in the possession of Yoda's last Jedi apprentice, Luke Skywalker. In 9 ABY, Skywalker offered the saber to Grogu, a young member of Yoda's species; who was being trained by Skywalker at his Jedi academy on the Outer Rim planet Ossus.
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.
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.
Vader eventually killed the Jedi Master and retrieved his green-bladed lightsaber. He headed to Mustafar, where he bled the saber's crystal, turning it from green to red.
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.
Purple. 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.
She carried the weapon during the Battle of Rendili, but it didn't taste first blood until she engaged in a lightsaber duel shortly after the battle with Asajj Ventress. After the duel, in which Padmé was victorious, the weapon was wielded by Skywalker for the rest of the Clone Wars.

The Forbidden Forms were forms of lightsaber combat used by the Sith during the Sith Wars. According to the testimonies of the Jedi Cervil the Uncanny, lightwhips—a lightsaber variant with a flexible blade—were used to defend against Sith Lords who utilized the forms.
Lightsabers with ghostfire crystal cores also generated almost no sound and produced illusory afterimages of the blade that followed the motions of the wielder, the most curious effect of all which disguised the true position of the blade while also disorienting foes.
The purple color itself is considered the most powerful lightsaber color in the Star Wars galaxy. A very few Jedis ever wielded a lightsaber of this color. The only two known people to ever wield a purple color lightsaber are Mace Windu and Darth Revan from the past.
Description. Bleeding was accomplished by pouring rage, hate, fear and pain into a kyber crystal by means of the dark side of the Force, until the crystal changed, resulting in the crimson-bladed lightsabers associated almost exclusively with dark side adepts.
