How do I adjust the color balance on the webcam?

I think the picture from the webcam built into my Razer Blade 2016 is slightly too blue.

I've tried taping a magenta or a yellow gel in front of it (thin polyester film) but the auto-balancing actually undoes the adjustment, unless I put it on really heavy, at which point the picture quality significantly degrades.

If I could adjust the properties of the webcam to set the auto-white-balance to be slightly warmer, this would be great! But I can't find any app or control panel that lets me do this.
