It’s a cool idea, but wouldn’t a more mystical reason make more sense in SW? E.g. the idea of bonding with a living crystal if you’re a Jedi, or “bleeding” it if you’re a Sith.
I don’t get why so many people don’t like the new lightsaber crystal lore. It’s such a Star Wars-y concept. They’ve even named them Kyber crystals.
This is sort of where I’m at.
If anything I’m against any explanation of lightsaber color.
