Turn Ben’s Saber (in the TLJ flashback scene) to Green to really show and dig in that “New generation of Jedi” Idea.
I always thought saber colors had a theme:
White : Jedi Knight
Green : Jedi Master
This fit Luke’s path in ROTJ.
It fit Qui-Gon and Obi-Wan in Phantom.
AOTC…kind of followed that pattern. Yoda had green, Anakin and Obi-Wan had white.
But then Obi-Wan always had white even as a master while on the council…so it basically fizzled out as an idea with all the various extra Jedis just being whatever and it was clear Lucas didn’t follow the master-knight theme.
