As far as out-of-universe is concerned, she does follow the color naming rule. In-universe, it's really complicated to think about whether or not she follows the color naming tradition. I see what you mean.

Whatever the name "Yang" means in their universe, it likely adds up to "yellow" in some way, in order to be consistent with the color it adds up to in our universe, plus her habit of having a connection to yellow.

Though, it seems that characters may not always have a frequent connection to their color. Ren barely has any pink, but that's his color.
