Honestly, that short in Visions was the only one that actually broke what amounts to canon in the Star Wars universe and it did it in such a way that I want it to be the new canon. Like, if a Jedi didn't want to be immediately outed as a Jedi while using their laser sword, they'd have to fill their minds with hate and fear and such, while if a Sith wanted to be sneaky they'd have to do the opposite. Lightsaber colors shifting during a conflict to represent psychological changes in resolve, stresses, and damage. Lotta storytelling potential there.I kinda knew about it from hearing some people whine about it("X character had the WRONG LIGHTSABER COLOR!"), but it slid down the old memory hole until VIsions came out. The Red lightsabers came out in the one episode and then I kinda remembered something about Red being the Sith color or something. Apparently they're like mood rings or something where they detect your alignment. If you're a true neutral is it pure white? What if you're chaotic good? Does it turn Topaz?
Star Wars suffers from the Greedo Problem. See, Greedo was a bounty hunter who briefly held Han Solo at gunpoint. Therefore, every member of Greedo's race is a bounty Hunter in some fashion, on a broadly societal and religious level, regardless of actual profession. The entire race is fanatically devoted to bounties, to the point that they make bounty runs to grocery stores to pay bounties to farmers who supply a bounty of crops.
It's clearly stupid, but like, Obiwan and Anakin had blue lightsabers, Jedi Knight Luke had a green lightsaber, and Vader had a red lightsaber in the original trilogy, so obviously there were hard and fast rules for what that meant on an tangible immutable galactic level and it wasn't just a specific storytelling device.
The Sith do love their over complicated lightsabers. It's more of a tell than the color, honestly. The instant you do anything other than a straight handled, single bladed design, look outMaybe that's what I remembering. I didn't think anything of it. Jedi Masters probably get to do what they want. Maybe that's why Anakin was so mad about not getting a spot on the council, because he wanted a purple saber too.
I mean, Maul had a double saber and Kylo Ren(?) had a saber with a cross guard made of sabers and....sure, why not? Apparently Blinging out the laser swords is a thing.
