Excerpt:

There are technically three types of vampires.  They come color coded like m&m's or jelly beans or packets of hot sauce or types of beer.  White are the most mild.  Barely vampires.  Whites are with out fangs and completely human in appearance.  Every white needs some thing specific, a type of energy, to stay alive and active.  If they can not get what they need to stay alive, they die just like humans.  Kind of bland, kind of pale, without much punch, always in need or some thing; white.
Then you have your reds.  Me, Johnathon, Dianna; we are reds.  We look human, aside from the retractable fangs.  We get what we need from blood.  Any kind of blood.  Human is not necessary though most prefer it. Social norms and taboos exist even in the underworld of vampyre.  If we do not feed we get cranky and turn feral; which forces us to feed.  Nice naturally built in defense mechanism.  Reds have heightened senses and can move a little faster then the average human.  Reds can heal to some extent but die out right from most injuries that would out right kill their human equivalents.  For example, car crashes can be as deadly to a red that has not fed recently as to any normal human.  We are the kind most people think of when they think vampire.  Though the whole steak through the heart, garlic, and sunshine things are a load of bologna. For the most part, the myths you hear about vampires are really just stories about reds.
Then you have your blacks.  Creepy as all fuck and just as deadly.  Take Johnathon multiply by a thousand and add a feral edge, complete lack of hygiene, and a rotten earthy stink and you got black.  Blacks are the ones that give the rest of the vampire gene pool a bad rap.  Nosferatu are blacks.  There is some debate about Dracula having been a black; but I always thought of him as a red who was lackadaisical in the feeding department.  Evil, dark, decrepit; black.
