A kyber crystal has no color until it is approached by a Jedi, it then turns into a color determined by the wielders connection to the Force. The color of a lightsaber's blade is given by a kyber crystal. The Sith wield exclusively red-bladed sabers to distinguish themselves from the Jedi. The most common lightsaber colors are blue and green, but other colors also exist, that being purple, white, black and yellow. The Jedi use different colored lightsabers. However, the lightsaber can also be wielded by non- Force-sensitive characters as an ordinary weapon or tool. In the Star Wars universe, the lightsaber is the signature weapon of the light-side-wielding Jedi Order and the dark-side-wielding Sith Order. The lightsaber's distinct appearance was created using rotoscoping for the original films, and with digital effects for the prequel and sequel trilogies. First introduced in the original Star Wars film, it has since appeared in most Star Wars films, with at least one lightsaber duel occurring in each installment of the ' Skywalker saga'. A typical lightsaber is depicted as a luminescent laser sword about 3 feet (0.91 m) in length emitted from a metal hilt around 10.5 inches (27 cm) in length.

A lightsaber is a fictional energy sword featured throughout Star Wars.
