In the current Star Wars canon, the primary character known for using white lightsabers is Ahsoka Tano.
While white lightsabers are most famously associated with Ahsoka Tano, they have made other appearances in Star Wars lore. Jedi Master Orla Jareni wielded a white lightsaber during the High Republic era, and in Legends continuity, the Imperial Knights carried silver-white blades.
The rarest lightsaber color is arguably black, embodied by the unique Darksaber created by the first Mandalorian Jedi, Tarre Vizsla, with only one ever existing; however, white (Ahsoka Tano's purified crystals) and purple (Mace Windu's) are also exceptionally rare, symbolizing unique paths outside the typical Jedi/Sith dichotomy.
Ahsoka Tano has famously wielded white lightsabers, representing her journey toward enlightenment and self-discovery.
White sabers appear rarely in the Star Wars universe—so rarely, in fact, that the current canon recognizes only one carrier of a white lightsaber. 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.
Ahsoka Tano from Star Wars: The Clone Wars can also technically be called a Gray Jedi, due to her forsaking the ways of the Jedi, but still following a path of good. However, neither of these two ever trained to use the dark side of the Force, so they are arguably not "true" Gray Jedi.
In comic series like Star Wars: Legacy, Gray Jedi lightsaber colors are most commonly associated with white or silver blades. The reason behind this is believed to be that because Gray Jedi walk a fine line between the Light and Dark Sides of the Force, their lightsaber color remains neutral.
The Acolyte's sixth episode reveals Qimir was once a Jedi, making him a formidable dark side user.
Tràkata is a rare and cunning lightsaber technique built on deception and misdirection. Jedi like Kao Cen Darach and Cal Kestis used it to gain surprise advantages in battle, while Sith like Qimir mastered its lethal precision.
Currently we have a total of 13 to 14 lightsaber colors in Star Wars Canon: Blue, Red, Green, Purple/Violet, Light Blue, Yellow-Green/Lime, Yellow, White, Indigo, Magenta, Cyan, Orange, Red-Orange/Orange-Red and the Darksaber (if you count it as it's own color seperate from white).
Form VII, known by its two primary disciplines of Juyo and Vaapad; and also known as The Ferocity Form, was the seventh form of lightsaber combat. It was considered the most aggressive and unpredictable form.
Mara Jade, with her iconic magenta lightsaber, stands as a pivotal character in the Star Wars expanded universe.
While he is not Force-sensitive, Grievous has been trained in all forms of lightsaber combat by Count Dooku. Each of his mechanical arms can separate in half, allowing him to wield four lightsabers at once to overwhelm his enemies.
This white Kyber crystal comes in a detailed capsule and is made to be used with a Holocron and some Lightsaber models* to activate special lights and sounds inspired by the Star Wars saga, including character voices. The Force guides the Jedi in selecting a crystal, let it guide you.
Gray Jedi, independent Force wielders, reject strict Jedi and Sith ideologies to seek balance. Figures like Qui-Gon Jinn, Jolee Bindo, and Revan embody this philosophy, blending Light and Dark Side abilities without falling to corruption.
The crafting process essentially purified the kyber crystals, turning them into a color that befitted her status as an autonomous individual. This is how Ahsoka Tano's lightsaber was born and what the white lightsaber represents—a force for good, but free of the burdens and restrictions of bureaucracy.

While not a common color, among the few characters known to wield a cyan lightsaber, Cal Kestis stands out as the most prominent. Originally wielding a blue blade as a Padawan under Jaro Tapal, Cal's lightsaber underwent significant modifications after his master's demise.
The Lost Twenty, also known as the The Lost, was a name given to the group of twenty Jedi Masters who left the Jedi Order throughout its history. According to Yula Braylon of the Jedi High Council, the Lost Twenty became disillusioned with the Jedi way of life.
The clone commando RC-1136, known as Darman Skirata, got Jedi Knight Etain Tur-Mukan pregnant during the Clone Wars, resulting in their son, Venku Skirata, a Force-sensitive child born outside the Jedi Code's restrictions. Their forbidden relationship and child's birth were detailed in the Republic Commando novels, highlighting the complexities of clone troopers' development and the strictures of the Jedi Order, as Etain was killed shortly after Order 66 while protecting her family.
After meeting the former Jedi Ahsoka Tano, Grogu went to Tython to meditate on a seeing stone in search of other Jedi. Although he was captured by Moff Gideon and his Dark Troopers, Grogu was rescued by Djarin and the legendary Jedi Luke Skywalker, who heard him through the Force.
