i think there's a debate about white gold looking different from certain jars, but mine has a greenish reflect while vanilla has more of a pinky-yellow reflect.
I just bought a jar of white gold from the pro store and they said it was part of the permanent collection. Unless it has been discontinued in the past couple of weeks, it should be easy to get. It is white and flashes gold and green. It's gorgeous. Vanilla is white and flashes gold and peach. It is an absolute staple of mine. Both are really nice.
