Ritual Hunter's visions don't change. It stays as cold (vlue) heatvision. Only sounds change.
On Alien Hunter's costume, the background color only changes from cold to warm (red). The sounds also change. Although the heatvision look of the pred and humans still stays like as cold heatvision mode.
On Dark Blade Clan's costume, sounds change, cold to to warm background and the heatvision look of pred and marines change also. To more like in AVP movie.
About Bad Blood costume, I don't know. Haven't played as him for a long time, so I can't remember.
