There are a number of fur based armors that would be absolutely incredible, if only we were allowed to dye the fur portion of its features. The new moongrave fane being the latest, but most of the nord armors and a few others would all benefit from this aspect in my opinion.
Especially with Skyrim coming, I hope this can be made possible with preexisting or even future motifs.
This simple change creates the option to appear to have long hair under helmets. The missing piece for my nord barbarian.
