Nose colors are no longer available for werewolves, and for any existing werewolves itll reset as soon as you bring them into cas. I of course have no mods or cc in my game right now as its right aft...
Ideas
So I found a workaround as a temporary solution. Go to CAS of your werewolf, Press Zoom In, Press Detail Paint Mode. Now Paintbrush the nose, eyelids, and inner ear to your desired color.
Do you think it's really going to work?
