@Asket - when an image has an overly blue (or green) tinge, it may be worth trying to 'fix' it by accessing the hue/saturation menu (ctrl+u) then choosing the blue (or green) option instead of master, then turning the saturation for it right down 😉

P.S. If the person has a blue (or green) collar, select it before the above step, then right-click on the image to select inverse. This way, the collar isn't affected 😉
