Why does Ahsoka have white lightsabers?

This is a cool one. Ahsoka, who dual-wields lightsabers, had blue lightsabers during her time as a Jedi padawan. But after she left the Jedi Order, she stole Kyber crystals (which power the sabers) from the Sith, and used her Force powers to drain them of their characteristically red hue, turning them white. The color of her sabers represents her unique status—she is a Force user, and perhaps more a true Jedi than others, but she does not belong to the Order and exists in a sort of limbo. I could get started on Gray Jedi, but that’s a conversation for another day.
