If you really like that cam and want to do a workaround, since the color is shown yellowish that means you would need the opposite color to controvert, which would be blue. So either have a more bluish light in the room which would be a florescent 5600K light or tape a small piece of something lightly tinted blue like colored plexiglass or something to either the camera lens or to the light source in the room. That would get your balance back to normal. I do it all the time with our video cameras.
