Why are there different color lightsabers in star wars?

Answer 1

Lightsaber colors
In the original film trilogy, lightsaber blades were blue, green and red.

The various Expanded Universe (EU) sources, action figures and the prequel films opened up the spectrum of blade colors to many variations of the aforementioned colors, as well as yellow, purple, orange, silver, turquoise, pink, bronze, viridian, brown, grey (and possibly white), gold, and black, among others; the full variety and extent of focusing gems, and consequently, of colors, is unknown. According to the Expanded Universe, these gems merely determine the blade color. However, in Star Wars: Knights of the Old Republic, different gems may alter the intensity or damage type of the blade (making the blade more accurate, or more effective against droids, for example), in addition to altering its color. Though it might be worthwhile to note that in these games, separate crystals are used to perform different functions, and only one type of crystal is used to change the blade's color.

Red and bronze colors are usually associated with the Sith. Purple, turquoise, yellow, blue, and green colors are associated with the Jedi. Orange, silver, pink, white, gold, and viridian typically do not represent either side. However, the Expanded Universe establishes no direct relationship between a lightsaber's blade's color and its user's affiliation. For example, the Dark Jedi Sariss used a blue lightsaber while her erstwhile ally Yun used a yellow blade. Both are from the computer game Jedi Knight.

Usually, the reduced amount of colors present in later eras is attributed to the Empire, which destroyed the caves that housed the lightsaber crystals used to focus energy and create the blade's unique color. Synthetic crystals were created to replace the natural crystals found in caverns, typically having either a blue or green color. During the Old Republic era, Jedi kept strict traditions that kept most padawans from creating their lightsaber crystals synthetically, either within a furnace, taking a gem and restructuring it via the Force, or a combination of both.

The color of a lightsaber blade depends on the crystals used to focus it. Blue-bladed lightsabers are associated with Jedi Guardians; green-bladed lightsabers are associated with Jedi Consulars; yellow-bladed lightsabers are associated with Jedi Sentinels; and red-bladed lightsabers are more closely associated with the Sith and dark Jedi. Note however, that the color of the lightsaber does not necessarily indicate the nature of the Jedi. Mace Windu's purple-colored lightsaber in the movie was colored differently because Samuel L. Jackson asked for it to be so. In the expanded universe purple, being a mix of red and blue, shows the mastery of a lightsaber form known as Vaapad or form VII and the light side of the Force which allows Windu to use his fighting style and Force powers dangerously close to the Dark Side without being tainted. It is also said that a purple crystal is a choice only the most skilled masters in lightsaber combat can make, which might also explain his unusual blade color. Usually the lightsaber crystal will call out to its chosen master during the trials to become a Jedi when the padawan travels to Ilum or Adega. This in part is why some sources claim that Jedi traditionally use Adegan crystals. In the Star Wars comics, Mace Windu, as part of his training as a padawan, was left to survive on a planet with living-mineral organisms. These natives represented tall, long faced humans with grey skin with purple gems scattered throughout their bodies. Mace Windu escapes an attack of two of these organisms by leaping a gully, but one of the mineral-men fell in and was smashed. Mace Windu stopped and concentrated with the force to painstakingly reassemble the fallen creature and over several hours saved its life. Thus Mace Windu became an ally to these mineral-men. To express thanks, the mineral-man he saved gave Mace Windu some purple crystals from its body. The purple crystals are what gives Mace Windu's lightsaber its special color.

Prior to the Battle of Ruusan, Jedi used lightsabers in a vast array of colors. Afterwards, Jedi relied on more common Ilum crystals such as blue and green. During his Knight Trials, Mace Windu braved the rock-encrusted world of Hurikane on the orders of his Jedi Master to obtain his lightsaber crystal. He encountered the planet's natives and, in a moment of panic, accidentally threw them over a cliff. Realizing his mistake, the young Padawan saved the natives. It was from this mission that Mace Windu was given the rare crystals as a gift. In the New Jedi Order era, Jedi had a wide array of colors such as orange, yellow, green, blue, purple, and light blue.

The synthetic red crystals favored by the Sith can create a somewhat more powerful blade than blue or green crystals but are generally not as pure because of their artificial nature and can thus be undesirable as the focus of a lightsaber. The Sith apparently had a large supply of red crystals and also favored red as a symbol for passion. It was not uncommon for the Sith masters to supply their learners with the synthesized red crystals. However, Darth Vader, at the beginning of his Sith period, wielded a blue lightsaber, as shown in Revenge of the Sith. Likewise, Exar Kun used a blue double-bladed lightsaber in the Sith War.

Sith lightsaber crystals tend to be red because of Sith Alchemy. When making their own lightsaber crystals, the materials they use and the way they make them almost always turn out crimson. Though most Sith wield a red lightsaber, the color does not affect their decision to use the lightsaber. For example, if the blade turned yellow when first ignited, it would make no difference to the user.

Luke Skywalker constructed his lightsaber using instructions hidden in Obi-Wan Kenobi's abandoned hut on Tatooine. Instead of using natural crystals however, he synthetically created the focusing gems within a compact molecular furnace, also found inside Kenobi's home. While the intense heat of the kiln molded the base materials that Luke had placed inside, he channeled his Force energies through them, which in turn shaped and modified their internal properties. With this process, a completely functional lightsaber crystal can be created. Darth Maul was known to have created his double-bladed lightsaber in much the same way, but with one major difference. During the forming of the crystals within the furnace, the Sith focused all of his blinding rage, aggression, and malice into the gems. This leads to the belief that it may be possible to mold the alignment of the completed crystal itself through this process.

During the initial editing of Return of the Jedi, Luke's lightsaber was colored blue in a trailer. However against the desert blue sky environment, the decision was made to change it to green for a better visual effect, hence the birth of the green lightsaber. It has later been retconned to be the color of a "Jedi Consular", a Jedi who focuses on mastery of the Force rather than lightsaber combat.

Answer 2

Different Lightsabers

Answer 3

Different characters of Star Wars use their personal lightsabers:-

Red is generally associated with Sith.
Blue/Green is related to Jedi
Purple was the personal request for Samuel L. Jackson.

Answer 4

The lightsaber manufacturer decided that it would be easier rip the money off of the young Jedi's if they make it colorful and attractive to the kids. In the end, all the Jedi's were killed anyway, including the young ones.

Answer 5

each jedi make their own lightsaber out of a force crystal. It reflects their inner soul.

Answer 6

It would be kinda lame to have all the lightsabers the same color.

Answer 7

Red is for bad guys
blue is for good guys

Answer 8

for differentiation of course!
you already could find out who`s fighting on the battle by seeing the light-sabers

Answer 9

the different color light sabers represent the kind of jedi or sith they are :)

Answer 10

it signifies what they are. i can't remember the list of color to jobs. if my room mate wasn't sleeping i'd ask him. he'd know.

Answer 11

So we can distinguish between the good guys and the bad guys.
