Also, Rey’s saber lights are green and blue, referencing presumably Luke and Leia’s sabers but not that she used their crystals. Having green and purple would retain this nod for this edit. I’d prefer that over blue and purple.
Counterpoint - Rey never sees Luke’s green saber and unless she heard stories about it’s color somewhere she would only know his blue one, the one she is obsessed with ‘earning’ throughout the film.
