Anyway, I did not know that Clone Wars had a yellow lightsaber; that's pretty cool.

A couple, actually. Ahsoka's yellow saber is a shorter one she uses along with her full-sized green one, so it sometimes looks greenish-yellow, though I attribute that to either the fact that it's always seen next to the green one, or the background color fucking with the saber glow.

Here's Ahsoka with both of her lightsabers fighting a Mandalorian with an ancient proto-lightsaber ("darksaber" or something):

And then there's the Jedi Temple guards with yellow lightsabers - they're only seen toward the end of Season 5 though:

Not really relevant to your project so much, but these are the only canon examples of lightsaber colors other than blue, red, green, or purple (which is why I threw in the "darksaber" as well, even though it wasn't really part of the discussion).
