With multiple light sources, the white balance is undefined and you need to compromise somehow, yeah. Even a scene where there is strong sunlight and a bright blue sky will make white balancing quite difficult, as the shadows are lit with sky blue skylight and the sunlit parts are lit with the sun. I use darktable and it's possible to correct the blue tint in shadows, but like... it's annoying. And at some point I'd say fuck it and just accept that photography is not a science.
