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 lightsaber's crystal, turning it from green to red.
Anakin traveled to the river moon Al'doleem to do just that, slaying Jedi Master Kirak Infil'a and confiscating his lightsaber. This was a curved-hilt saber with a green blade. From there, Anakin went to Mustafar to bleed the kyber crystal and turn it Sith red.
Upon reaching the planet's surface, Vader entered a cave that was strong with the dark side. He dismantled the curved-hilt lightsaber and placed the Jedi Master's kyber crystal on a rock. Using the Force, Vader began subjecting the crystal to the bleeding technique.
Unlike the natural kyber crystals that produce the iconic blue and green sabers, where do red kyber crystals come from are synthetic and created through a process that involves bleeding a crystal's color using the dark side of the Force.
Rather than being found naturally on worlds such as Illum or Christophsis, red kyber has to be made by the Sith. After procuring natural kyber (no matter the color), a Sith Lord corrupts the crystal using the dark side of the Force in a process known as "bleeding".
After destroying the Jedi Temple in 28 ABY, Ren used the dark side of the Force to bleed his lightsaber's kyber crystal, changing the color of its plasma blade from blue to red.
So, that's the real reason Anakin's saber didn't change color -- because the process of lightsabers changing colors (after bleeding) didn't exist as a concept when Revenge of the Sith came out. At the end of the film, Darth Vader loses his lightsaber during his duel with Obi-Wan.
Traditionally, yellow lightsabers are associated with Jedi Sentinels, who balance their combat skills with a strong focus on exploration and practical application of the Force. This choice reflects Rey's well-rounded training and her determination to maintain balance in the Force.
When Ben Solo became Kylo Ren, he chose a lightsaber with a cracked kyber crystal within it. This meant he had to give his lightsaber an unusual design, using a crossguard hilt with quillons to control and direct the energy streams to each side and prevent the lightsaber overheating.
History. Like many Jedi did for hundreds of years, Yoda built his lightsaber under the aegis of Professor Huyang, an architect droid who had been with the Jedi Order since its nascent days. As a first step, Yoda acquired a kyber crystal from the icy caverns of Ilum, a mission that proved to be very eventful.
Ahsoka's white lightsabers first appeared in the TV episode "Fire Across the Galaxy", the season one finale for Star Wars Rebels. According to Dave Filoni, one of the show's creators, the lightsaber blades are white to reflect her non-affiliation with the Jedi or Sith.
Pink sabers, also known as magenta sabers, are indeed a part of the Star Wars canon. They are quite rare and symbolize compassion, empathy, and great control with manipulation. Cal Kestis, a character from the Star Wars Jedi: Fallen Order game, has the option to wield a pink or magenta saber.
After his reincarnation, Darth Sidious aka Palpatine used a blue-bladed lightsaber when he fought Luke onboard his Super Star Destroyer Eclipse. Ultimately, Sith who wielded colors other than red were usually looking to disguise their dark affiliations.
Why is Luke's lightsaber green when Anakin's was blue?
The main reason for the change was that during the filming of Return of the Jedi, the crew realized that the blue saber did not look right during the battle with Jabba the Hutt. When shot in daylight, the blue would blend with the color of the sky, so George Lucas and his crew decided to make the change.
However, the reason Kylo's blade is crackling is because the Kyber crystal was fractured as he bled it, turning the blue blade red. This is also why he constructed a special crossguard saber, in order to contain the dangerous energy of the fractured crystal.
Construction. 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.
Kylo Ren's obsession with Vader is clear, but Star Wars never explained how he acquired the helmet. It is speculated that he may have found it himself on Endor, or it could have been passed down to him by Supreme Leader Snoke.
This was all because of its cracked kyber crystal. As with how the Siths get their red lightsabers, Kylo Ren made his kyber crystal bleed to get its signature color, but typically, this process doesn't result in a defective gem, hence why no one else has a ragged blade in Star Wars.
The fate of Luke Skywalker's old lightsaber appeared to be symbolic of his philosophy; it was shattered in a Force tug-of-war between Rey and Kylo Ren. Even its Kyber Crystal was broken. And yet, in spite of that, Rey succeeded in repairing the lightsaber in Star Wars: The Rise of Skywalker.
