Why is Rey lightsaber yellow? Like the quarterstaff from which it originated, Rey’s lightsaber hilt was blocky and heavy due to its exterior armor that made it resistant to impact and wear and tear. The weapon had a kyber crystal at its heart, and emitted a yellow-colored plasma blade when ignited.
