Colours and breeds

There are a couple forums I am on that are really bad for this (they're mainly meat raising forums) where someone gets a rabbit that is a colour of a specific breed so it obviously can't be anything but that breed.

Just because a rabbit is chinchilla in colour does not mean it is an Am. Chin many other breeds have the chinchilla colouring and so that means obviously mutts can come in that colour. Unless you have papers stating otherwise then it is not anything but an "unknown" breed. New Zealands and Californians are others that are routinely picked on, it seems every white rabbit is a New Zealand and every cal marked rabbit is a Californian, again both colours are in almost every breed out there so logically it would be in mutts as well. Sables are also another that routinely crop up, Palominos, and every chestnut rabbit seems to be a flemish even though it's 3lbs.

So unless you bought said mystery rabbit from a breeder that breeds the breed in question, then chances are it is nothing but a nutt and not magically some (usually) uncommon breed.
