Blade Color: Unique
The Full Spectrum Effect
A lightsaber's blade color comes from the type and quality of crystal used to power the weapon. In addition to the common lightsaber blade colors such as red, blue, and green, there are also a myriad of other colors seen in the Star Wars universe. Some variant colors are used to symbolize rank or status. Others are different because of creative requests or the need to make a character stand out from the crowd.
With the exception of Mace Windu's iconic amber lightsaber, unique colored lightsabers are not seen outside of the films, appearing mostly in the Clone Wars series.
