You know, I obtained the black dye (and the other DLC dyes that no one would ever use) and once I had it, I experimented a bit and decided it was too bland. The black is SO black that it steals all the texture away from whatever you put it on. Now I'm back to imitating the Albion army colors of red and brown.
I agree, after applying black to the hair, it looked totally **** and changed it back straight away, same goes for the clothes. I was disappointed we had to buy them in the first place, i'm even more disappointed now i have them.
