You're quite right Natalie, they KC will register all pups regardless of colour in any breed unless either of the parents was not KC registered, the bitch was over or under age at the time of birthing the litter, more than the maximum number of litters had been bred from the mother, or one or both of the parent's registration docs was endorsed "progeny not for registration".
Despite registering them within the guides above, the registration document
should automatically be marked as "colour not standard" if the colour or description of colour is not exactly within the rules laid out by the specific Breed Standard. So in this case "Champagne Blue" should be quoted as "non-standard" on the docs ;) But they have been known to make mistakes before ....
