The trouble is that there is that many colours and then shades of colour on top of that, people are bound to be confused, If it were me I would simply register a reddish pup as gold, and a creamy (Champagne) as Lemon. It cuts down on the confusion. As we will get to a situation where we will be having "Ribena or Lucozade coloured pups"
Hopefully in time the Kennel Club wll give Clarity on what colours we can and can't use when registering as it is becoming a wee bit ridiculous
