Blade Color: Blue
A True Galactic Guardian
The color blue symbolizes goodness in the Star Wars universe. It's the embodiment and tone of the Light Side. Jedi who carry a blue lightsaber tend to be honorable, obedient, loyal, and righteous (with some exceptions... like young Anakin Skywalker). Blue-wielding Jedi Masters are often generals, proficient in martial and strategic arts.
The first two Star Wars films ever made depicted lightsabers as either blue or red, symbolizing the dichotomy of the Force. This color metaphor was revisited in The Force Awakens, where red and blue tones appear in key scenes, narrating using color in addition to sound and dialog.
