The Star Wars Lightsaber Colors, Explained

There is only one black lightsaber that exists in the Star Wars universe. Known as the darksaber, this unique weapon was created by Tarre Vizsla, who was the first Mandalorian to become a Jedi and went on to rule his home planet of Mandalore. After he died, the darksaber was kept in the Jedi Temple but was eventually stolen by his clan, House Vizla. The lightsaber has since become an important symbol of Mandalore, and the only way to obtain it is by defeating its owner in a duel.
