Thanks ^^ Well, I thought about the colors matching her clothes and their function: blue that symbolizes protection and yellow thaht indicates a Jedi Sentinel, a Jedi who honed their skills in a balance of combat and scholarly pursuits.
aha you don't want to get too much into that because it is a choice for the individual jedi. What sect they belong to just influences that choice a bit. Therefor you can have guardians with green or yellow and vice versa.
Oh I see, I was conflicted with certain choices, like the colours of Belle's lightsabers. She is a scholar so yellow, but the other one... I just chose red because of her belt rose but now thanks to your explanation, the choice will be flexible thanks!
