I honestly think that Anakin should have a purple lightsaber. It would show that while he’s not quite as dark as Sith red (until he becomes Vader, of course), he has a dark side.
Idk. Cool idea it’s just that is the most iconic saber in Star Wars. I have grown (and thousands more) so attached to Anakin and Lukes blue lightsaber. Idk just my 2 cents
