Someone please correct me if I am wrong is there any point in season 2 where it was explained by a character why her sabers were white? I am a huge SWTOR fan I like have 5 characters in that game, since there is no clear distinct reference outside of a behind the scenes or a online media source from a producer I think I am going to stick with green. I just rendered her first sequence with green. There is no reason why she could not of stuck with her preferred color from the clone wars she was still a light side force wield knight so I would have to think she would have been able to find some green crystals after she left the order shortly before order 66. Filoni & co would have been vetoed on that one by George himself if he was still in the directors chair.
Just as a reference, this is a BTS webisode where Dave Filoni explains his reasoning for giving Ahsoka white/near-white lightsabers at the 3:00 minute mark. Not agreeing with it is totally fine, that is what fan editing is all about after all!

I agree that Lucas usually seemed pretty steadfast when it came to saber colors, but that seemed to start changing before he left. I mean, this is the guy who gave Samuel L. Jackson a purple lightsaber just because he asked for one with no real logic behind it. A Jedi Master in TCW episode “The Wrong Jedi” used a near-white lightsaber when Anakin was fighting Barriss Offee at the Jedi Temple, which you can see at the 2:17 mark. (https://www.youtube.com/watch?v=u6_0Y4nnylA).
This guy’s saber also appears in an earlier episode, “Lightsaber Lost”, which Filoni claimed it to be a very light blue in this Q&A, question 14 (https://www.facebook.com/notes/dave-filoni/qa/10150219391017571), but they clearly made it an almost white if not pure white in the Season 5 episode. It’s possible Lucas became more lax with saber colors during Clone Wars, since he apparently was also the one who came up with the Darksaber (http://www.ign.com/articles/2010/01/28/star-wars-are-you-ready-for-the-mandalorians).
With that said, these are your edits and I think you should go with whatever color you wish. After all, you’re the one putting all of the work into this, not me or anyone else, so you should pick the color you want. I think your reasoning for why she would go with green is sound, doesn’t bother me at all. And if you can go back a little earlier in that Rebels BTS video, Filoni talks about Ahsoka’s outfit and how he imagined her getting this ancient samurai-esque armor from an old Jedi temple somewhere, so if her outfit is an antiquated design, why couldn’t she have found yellow crystals (or the green) at the same place she got the armor? This train of thought actually makes me like the idea of the yellow lightsabers even more. As if she were harkening back to how the Jedi used to be. It would connect it with the Old Republic even more.
Bottom line, I don’t think there is a wrong choice, but I definitely think you should go with green or yellow if that is what you want. It’s the least you deserve for the work you have put into not only this but all of your other projects too. So I’m 100% behind your choice, just thought I would share my initial thoughts as well. Honestly, I’m more worried about how those damn saber-copters can be removed without messing anything else up…
