White balance is what normalizes the responses of red and blue channels to the response of the green ones, so as to provide equal data numbers over a neutral (grey) surface. It's not about colour, it's about space metrics, making it uniform across all (3, 4, or more - depends on CFA) colour channel axes.
None of the operations we are discussing here are about colour per se, in fact. They are about projecting the device space into a colorimetric space, where colour is known. Operations that are about colour are those that change colour.
