The purple lightsaber allows Jedi to express their individuality and showcase their distinct connection to the Force. It serves as a visual representation of their unique journey, experiences, and beliefs, setting them apart from others who wield more traditional lightsaber colours.
There's always the possibility of new colors being added, but as it stands in the official lore, the only colors possible (and what they represent) are the following: Blue - loyalty, stability, truth, justice. Green - growth, safety, harmony. Red - power, anger, hatred. Purple - nobility and wisdom.
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.
Mace Windu is a powerful Jedi Master and member of the Jedi High Council in the Star Wars universe. He played a critical role throughout the prequel trilogy. Darth Sidious ultimately killed him in his attempt to save the Republic. Windu's saber is unique in many ways, not least of which is its iconic purple hue!
The lightsaber's amethyst color was chosen by the actor portraying Windu, Samuel L. Jackson, who wanted a purple lightsaber because he was "the second baddest Jedi in the universe" and so he could find himself among the many Jedi featured in the Battle of Geonosis scene.
Star Wars NOVEL Finally Reveals The Meaning of Purple Lightsabers - Star Wars Explained
What is the rarest lightsaber color?
The black lightsaber, or Darksaber to give it its proper name, is one of the rarest lightsabers in Star Wars canon. Despite its rarity in canon, anyone who has seen the second season of The Mandalorian is likely to be familiar with the Darksaber.
Individuals who wield the purple lightsaber are adept at navigating between the dark and light sides of the Force. This ability makes it the mightiest among Jedi lightsabers. It allows Jedi Knights to feel and understand emotions that they might avoid due to the Jedi Code.
In the Thrawn Trilogy, Mara Jade started out as an assassin working for Emperor Palpat. Over time, he undergoes a transformation and eventually becomes a Jedi Knight. Her lightsaber is a pink lightsaber, also known as the "Emperor's Hand Lightsaber".
Was Mace Windu more powerful than Yoda or Sidious? No, but he had a unique ability called shatterpoint. Combined with his vaapad he could forsee where and when to break an opponent. He beat Palpatine due to this ability.
Out of all the kyber crystals, the Kathracite, with its light green colour, is known for being the weakest. Its blades are less powerful and not as strong as others. Despite being weak, Kathracite crystals were important in the Jedi Order.
However, a groundbreaking study conducted at the University of Leicester's Centre for Interdisciplinary Science challenges these long-held assumptions. The study suggests that, against all expectations, red lightsabers may actually be the weakest of the lot.
Ghostfire crystals were a type of rare and entirely transparent kyber crystal that grew from rocky foundations and formed precarious and nearly invisible spires of stone. They could be found on a handful of worlds in the Outer Rim Territories and most commonly appeared on mountain peaks.
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.
The Gold Lightsaber is one of the rarest Lightsabers to ever be seen. It is similar to the Yellow Lightsaber because of its similar color shine of the blade, but the blade is a bit darker and as a result, resembles more of a gold color. It represents a Jedi that is very strong in light side skills.
The Darksaber. The only black blade-like Saber ever made, constructed with fine Beskar, by the only Mandalorian to ever become a Jedi in the Order's entire history.
Sith hate who use Sith who use purple lightsabers because they believe they are not true sith, and they do not like jedi's who use purple lightsabers either because they think that jedi are cheating using dark side of the force and its powers but not fully falling completely to the dark side.
Darth Traya wielded three lightsabers telekinetically against her student on Malachor V. Kreia then returned to Malachor V, where she confronted Darth Sion and forced him to submit to her will.
There is not a “rainbow” lightsaber, but there is a “white” lightsaber which could easily be all the colors of the spectrum. I ddi some research on this, and the current canon has most of the lightsabers either being green, blue, or like the Sith, red.
Gray lightsabers are often associated with Jedi who do not fully follow the Jedi Code, but also do not fully embrace the Dark Side. These Jedi are often able to balance the light and dark sides of the Force and use their powers to serve the common good and are less likely to be influenced by the Dark Side.
Blue. The first lightsaber we see in the franchise is still hard to beat. It's clear, from the moment Luke first ignites his father's weapon, that it is indeed “an elegant weapon for a more civilized age.” As mentioned earlier, blue is a primary color, but it is also what's known in color theory as a “cool” color.
Darth Maul's double-bladed lightsaber is the epitome of intimidation and strength. Featuring two crimson blades powered by potent kyber crystals, it's a weapon designed for dominance and crowd control.
