"He might have been the last Jedi with a purple light saber or he got it to show that he had power"
A good guess, but not quite accurate. The actor who portrayed Mace Windu (Samuel L. Jackson) demanded that his Light saber be purple if George Lucas wanted him in the movie. George originally only wanted blue and green light sabers as a show of unity and theme, but he acquiesced to Mr. Jacksons request in the end.
If you are looking for a Canon (or In-story) excuse, then its because the Jedi Order only had access to so many Lightsaber Crystal Caves (my name for the caves where jedi find the crystals that are the heart of their lightsaber) at that point. The crystals in the lightsabers are what give them each their own unique colour. At that time the Jedi Order only had access to green and blue crystals (in general). Other colours were less common.
If you meant to ask if George Lucas gave Samuel L. Jackson any special accommodations, then yes. According to the bonus material on the complete saga Blu-Ray box set, the only reason why Mace Windu got a purple lightsaber was because when George told Samuel the "regular" lightsaber colors, Samuel asked, "No purple?" and George decided to grant him "his wish."
Green when he was a Jedi. Yes, but before he completed his training he had his father's (Anakin Skywalker also known as Darth Vader's) blue lightsaber. If his father hadn't cut off Luke Skywalker's hand, he would probably still have the blue lightsaber. And Darth Vader lost a valuable memoir by losing the blue lightsaber. After Luke lost his hand, he had to get a new lightsaber, which was green and that was the color he preferred than blue. And in my opinion his new green lightsaber is better. Luke later retrieved Anakin's saber and gave it to his wife Mara Jade.
Only if you really want it
You do not actually get a lightsaber. When you are on the RAS Prosecutor, campaign level "Alone", before you blow up abarricade look to your right and find the vent, which you probably have to blow open. Go inside it and turn to your right, I think, and go to the end of the shaft. The lightsaber should be there and a trooper corpse. It has been thought that the trooper may have tried to use it. The only perk to finding the saber is that you hear yourself say something like "An elegant weapon for a more civilized time. Heh. Well...times have changed." (You don't actually get to 'get a lightsaber'). Sorry, though it'd be really fun to use one during the game. :)
Yoda's lightsaber is technically called a "shoto," which is a short lightsaber. Only a handful of Jedi, including Anakin Skywalker's Padawan Ahsoka Tano, use a shoto along with their original lightsaber, which is not an easy thing to do.
Mace Windu's current lightsaber is purple, his old one was yellow.
There were only two Jedi to have a purple lightsaber. They were Mace Windu and Adi Gallia. Mace Windu was the only member of the High Jedi council that had a purple lightsaber.
It's actually purple and I don't know much detail as to how he got it, but he is famous for wielding a purple-colored lightsaber since the purple lightsaber crystals were nearly extinct at that time
You can't do that because there is room for only one lightsaber crystal.
Mace Windu's lightsaber color is purple. But all lightsaber blades give off a white glow along with the color of the lightsaber crystal inside, for the lightsaber produces the smell of ozone when activated
Master Windu is easily recognized because he is the only Jedi to wield the purple blade in combat.
green is the colour of oppo rancisis's lightsaber
It would make more sense if her lightsaber was purple. It is the girlyest color of known lightsabers. No offense Samuel L. Jackson. Though it is possible that Disney will give her a pink one in the new movie current and/or flashbacks.
Kyp Durron uses a red lightsaber in the Star Wars Expanded Universe.
Mace windu from the star wars prequel triology films. There are also many people in the book sequels that have purple lightsabers like Kyp Durron, Jaina Solo and Anakin Solo... PS. i did not make these people up they are part of the main series of books that take place after Return of the Jedi and they are canon.
you can find it on marketplace website
Each lightsaber contains a crystal, unique to the jedi/sith that wields it. To complete their jedi training, a jedi must find the crystal to complete the construction of their own lightsaber. In the early days of the galaxy, the Sith had both purple and red lightsabers, while the jedi have yellow, blue, and green. Later on, the Sith abandoned (for the most part) purple lightsabers, and jedis that are on the light-side of the force, but can also wield dark-side powers for good purposes, wield a purple lightsaber. Mace Windu, for example, uses a purple lightsaber because he can also use the dark side; his lightsaber form requires him to use it.
