A king has no sons, no daughters, and no queen. For this reason he must decide who will take the throne after he dies. To do this he decides that he will give all of the children of the kingdom a single seed. Whichever child has the largest, most beautiful plant will earn the throne; this being a metaphor for the kingdom. At the end of the contest all of the children came to the palace with their enormous and beautiful plants in hand. After he looks at all of the children’s pots, he finally decides that the little girl with an empty pot will be the next Queen. Why did he choose this little girl over all of the other children with their beautiful plants.
The seeds were all dead (burned, fake, etc.). The other kids cheated and got different seeds and planted them. The little girl didn’t cheat and was not able to grow anything because the seed was dead. She was the only one who didn’t cheat.
I went looking for this information because I have a character in my newest Star Wars story who needed a pair of lightsabers. I wanted her to stand out from the other blues and greens, but purple didn’t fit her personality. Anyway, this information was complied from multiple sites and definitions.
Blue - This color belongs to those Jedi known as Guardians. They tend to be the most visible of the Jedi and spend their time overtly protecting the galaxy. Wielders of this color blade tend to specialize their fighting styles and are more likely to practice “aggressive negotiations”.
Known Wielders: Anakin Skywalker, Obi-Wan Kenobi, Anakin Solo
Green - Green tends to be used by the Jedi Consulars. These individuals tend to be more interested in negotiating than in fighting. That isn’t to say that they never use their blades, simply that they will try to talk their way our before resorting to violence. They tend to be more grounded than the wielders of other colors.
Known Wielders: Yoda, Qui-Gon Jinn, Ahsoka Tano (The Clone Wars)
Yellow - Wielders of the Yellow blades are known as Jedi Sentinels. They lend an existence so secretive that most don’t know about them. Like the Guardians, they have dedicated themselves to the protection of the galaxy, but prefer to avoid the public light. Sentinels prefer to use technology, tracking, espionage, and surveillance to remove traces of the Dark Side from the galaxy.
Known Wielders: Bastilla Shan, Plo Koon
Red - Used primarily by the Sith Lords, the color of the Red lightsabers are caused by the synthetic crystals used to form the blade. This causes the crystals to be specially tuned to the use of the Dark Side.
Known Wielders: Every Sith Lord
Purple - Purple blades tend to favor wielders who have connections or had connections with the Dark Side. This could be people who returned from the Dark Side, were Dark Acolytes, or use Dark Side techniques.
Known Wielders: Mace Windu, Mara Jade Skywalker, Jaina Solo
Orange - Oranges blades are wielded by those Jedi who bridge the gap between the Consulars and the Guardians. They use both negotiation and combat to resolve situations, and are highly adept at both. Orange is another color used by the Sentinels, but wielding an orange blade does not necessarily make one a Sentinel.
Known Wielders: Plo Koon, Mandalorian Knights, Yaddle
Gold - Gold lightsabers tend to be favored by those who are strong in the Light Side of the Force. It is a rare color, and appears very rarely. This could be because it is often confused with yellow and orange. The differences can be seen if the three colors are held up together, but are harder to see when viewed separately.
Known Wielders: Qu-Rhan
Bronze - Bronze has only appeared once. That being said, it appears to be favored by wielders of great physical strength.
Known Wielders: Lowbacca
Silver - Those who wield silver blades tend to be the calmest of the Jedi. They appear to be the most in tune with the Living Force.
Known Wielders: Corran Horn
White - Often confused with silver, white blades are confusing in and of themselves. The majority of those who wield this color blade seem to be dogmatic and narrow minded. They appear to serve a master or a group with complete and utter devotion. This however, would not explain Ahsoka Tano wielded two white lightsabers in the new Rebels series.
Known Wielders: The Red Guard (Palpatine’s personal guard), Ahsoka Tano (Rebels)
Black - Similar to the white blades, the handful of individuals who have wielded black blades have been very narrow-minded in their view of the Force. Unlike those who wield white blades, however, those who wield black blades seem to operate alone, claiming no allegiance to any cause, ideal, group, or individual other than themselves. There is only one known instance of its appearance, and it is generally regarded as the rarest color.
Known Wielders: Pre Vizsla (Mandalorian Death Watch Leader)
These are the main categories of lightsaber colors. There are variations, such as Magenta (the color of Mara Jade’s first lightsaber and a variation of the color purple), Cyan (a variation of the color blue), and Pink (possibly a variation of purple or red). There are rumors of lightsabers whose blades have a black core and color around the outside, but they appear to have been more common around the time of the Clone Wars and no famous Jedi used one. There is also a rumor of mixed color blades, which as some support since one of the Jedi Knights who fought at the First Battle of Geonosis lost his padawan during that same fight and added her lightsaber crystal to his own lightsaber alongside his own.
+ some black-core pics from SWTOR
SWTOR is really neat because you can do a whole bunch of things with it. My Jedi Sentinal uses two sabers that I put crystals from the GTN in, with purple cores and a pink-purple aura.
