A great place to start and I know I recommend her site to everyone is eridox.com. Lisa is the one where I learned the majority of my genetic stuff from. There are a couple of other sites, but sadly I don't have them bookmarked on my laptop.
Just be ready to take in ALOT of information...there's the pointed pattern (black and tan/ cream, chocolate and tan/ cream) the dilute colours of blue and isabella, the clear or ee red. Then you have your solid colours and the patterns dapple, brindle, the list goes on and on. But that's just a small taste of the colour end of the genetics. Before considering colour, you should consider temperament and confirmation of a dog - but that's breeder talk and I have a few friends that are breeders so to understand what they are talking about I taught myself the basics, lol
Vizzla, I think the colour/ pattern you are looking for is Wild Boar that only occurs in wires and smooths.
