I have the Logitech C920 webcam the post mentions. The white balance truly is all over the place, especially if you don't have great lightning setup.
I ended up adjusting the image manually with v4l2-ctl (see for example http://manpages.ubuntu.com/manpages/xenial/man1/v4l2-ctl.1.h...) I also pointed my warm white light desk lamp towards the wall behind my desk and bounce a bit of light back on my face off the wall.
