Clone Wars and Rebels are both considered canon. Both have also shown a white lightsaber blade (in Clone Wars, it was a lightsaber disguised as a walking cane and in Rebels, it's Ahsoka's two new lightsabers). Also in Clone's Wars, Asoka's off-hand saber blade is lime-green while her main-hand saber is regular green. I don't recall seeing the yellow one though. *shrugs*
