Would there be anyway of making so the beard, eyebrow and the hair color are different? I'd like white hair with a black beard and eyebrows. Is this possible at the present time?

The hair color itself is a new "CLFM" entry that contains the RGB values The fair base hair texture is then tinted with that color. You could try to make a retextured black beard that won't get any coloring. The textures are in "Skyrim - Textures.bsa" under textures\actors\character\...hair, beards, malebrows, femalebrows.

Of course just changing the textures would affect every NPC in the game, instead you should make a retextured model, using the new texture and then add that body part into the game. Not sure if Nifskope can already open the NIFs, If not you need to use a hex editor. Adding the new body parts into the game should be possible with TESsnip.
