Since light source and it's temperature changes it's always a challange to fix it even after having all in RAWs. It's even a bigger challenge when you have lights of different temperature at the same time. Having a WB reference in a scene always helps in postprocessing when you have RAWs.
I fought againts that for some time and finally gave up. As someone has noticed it here - make it your own artistic vision as nobody except you would ever know how it really looked like, when you pressed a button.
What is interesting - when you set some WB in a camera using a gray reference and shoot a video, you are not trying to change WB in each frame to make it objectively correct under current light source found in this frame. When you look at the sequence of frames and see a movie, you are not so disgusted with different hues you observe because your brain translates it correctly anyway. If you make a photo coverage having all photos (from a concert) with the same WB setting, then most probably it won't look ugly because viewers would interpret it more properly. The problem occurs when you have a single photo to present. After dusk when outside (street, concert) and not using flash or strong artificial consistent light (football game) but when light sources change I get best results when I simply set WB to 2900K-3400K without using AWB.
