My camera doesn’t let me adjust it directly through the Logitech software for some reason, so I always have to do it through webcam properties on OBS. If you’re checking the auto white balance box and the number doesn’t change but the color does, that happens to me as well but you should know that it’s definitely changing, it’s just not showing you the updated number for the auto setting. It’s been an issue for me for a while so at this point I just play around with the white balance until I find something that I like because auto white balance makes my camera colors change way too often and it gets annoying when you’re live. You can also try playing around with the saturation to change the colors a bit.
