Hey Chobber, generally I undercoat all my models with White as I find it easier to work with and because I paint in many thin layers rather then a few thick. For the most part my vampires have a porcelain look to their skin which I achieve by starting with either a dark grey or a dark blue grey colour, after which I build up to a lighter shade by highlighting the prominent areas of skin such as the cheekbones, chin and forehead. I hope this helps, and good luck.
