The strength of the Jedi defines how strong a lightsaber is. Although, the purple color is very unique and represents both the Light and Dark Side of the Force. So, it can be considered the strongest Jedi lightsaber color.

All the lightsabers are cool and unique. According to my choice, I like the white lightsabers of Ahsoka Tano the most. You can get any of these at Zia Sabers.

Jedis did use red colors in ancient times. As Sith lords and Grey Jedis started appearing with red color, this color became a symbol of the Dark Side, and Jedis stopped using it.

Master Yoda used a type of lightsaber called Shoto lightsaber, which is a small lightsaber. You can get a Shoto lightsaber for your kids at Zia Sabers.
