As I stated, the surnames are usually secondary on the naming rule. This applies to Team RWBY as well.

There's that theory that Yang isn't even her real name, so that's likely one of the reasons why her surname doesn't refer to yellow.

Alternately, since her name is in theory, a chinese name, it's normally read fully, translating as "Little Sun Dragon".
