Too many times people let the wrapping determine the package, The color is nothing more than skin & hair covering up the dog, that can come in any color, basicaly get rid of that part and all you got is a dog.
Then like Circle C says in his reply it will depend more on the individual bloodlines for temperment & disposition. Go tag along with a few different folks, (and help handle their dogs, with their permission of course) You will find that some are laid back, others very, very, hyper all the time, Ect, you can start getting a feel for different dogs, then you will know what you like and don't like. That is a starting point, then if one really stands out in your mind find out everything you can about how it is bred & raised, and try to find a dog with same genetic make up.
Bingo, if your looking for dogs of your own print that post out and tape it to the frigde door

Me personally, I like Catahoulas but I've seen quite a few BMC that I wouldn't mind owning either
