White balance is what

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.
