I think (but I'm not sure) that Ulfric's clothes get the same color as the others on females. Korir, however, definitely has the same kind of clothing, of the same color as Idgrod and Bryling.
Yeah, it looks like Ulfric's are unique, but I guess they revert to the standard ones when the PC wears them. I have no experience in this matter as I have never killed Ulfric.
If you say so! None of my characters have touched the DB questline so far. I've read that she's essential until after a certain wedding mission, but I might be wrong.
I'm not sure what you're mocking here.

I have pickpocketed http://i1209.photobucket.com/albums/cc398/buckomccane/Skyrim/Brylings_clothes_01.jpg off of her. It was on my Assassin Chick after the wedding tragedy.
I don't know if she drops her essential tag if you destroy the DB - I was asking, Dork.

I can try to kill her on my Warrior Dude who has destroyed the DB (reload after

). I have no pickpocketing skills on my Warrior Dude, but I may level it up so I can put weapons on NPCs that I like. If I do, I'll try to pickpocket her clothes off of her, but I think she has to be non-essential to do that, too.
