Just now, Kyla said:I have to disagree. The only source stating Ashoka's lack of being Jedi was provenance for the white lightsabers was Dave Filoni, who specifically said, "the white blades reflect her non-affiliation with either side." However, this was outside the context of canon and done as a discussion during the design and development of the character for Rebels. It speaks to what he was thinking when he wanted to give her uniqueness.
The canon was what was written in the book Ashoka, which states that the crystals were "healed" and upon being healed emitted a white blade. The book makes no determination that it was Ahsoka's separation from the Jedi that was the root cause, merely the healing of the crystals. While Dave Filoni may have intended that to be the case when he made the design choice for the color, that has nothing to do with the in-universe reason for it.
Yes, the blades were healed, which is why they stopped being red. However, given that Dave Faloni is one of the people specifically in charge of the canon, and he created Ahsoka, if he says that the reason why they turned white instead of some other color, is because she wasn't a Jedi, then, barring any contradicting information within the story, that is the reason why they were white. The Ahsoka novel doesn't contradict Faloni's statements regarding Ahsoka's crystals. And, in Rebels , she does say the reason why her blades are white was because she isn't a Jedi.
