No, it’s not explained (don’t really think it has to be either).Apparently there's a running change on Hasbro's Baylon and Shin figures to give them orange sabers instead of the red ones they were originally issued with.
I didn't watch the show, so I was just curious....why? Was it ever explained why these two have orange lightsabers??
But the simple answer really is that they’re not Jedi or Sith, and not truly good nor evil.
