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 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.
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.
Rey Skywalker, once known only as Rey, or as Rey Palpatine, was a human female Jedi Master who fought on the side of the Resistance in the war against the First Order. A former scavenger from the planet Jakku, her life was changed by the tumultuous events of the last days of the New Republic Era.
Ahsoka Tano, a Togruta female, was the Padawan learner to Anakin Skywalker and a hero of the Clone Wars.
Despite their biologic nature, rainbow gems could be used as lightsaber crystals. Tenel Ka Djo, the Princess of Hapes, had a tiara of rainbow gems worth the price of an entire solar system. She used some of the crystals in her second lightsaber, after her first one malfunctioned and led to the loss of her arm.
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.
