Lab7, perhaps you haven't been on here long enough to realise how passionate I am about dogs - all dogs, I love then all, regardless of breeding. But I am a stickler for correctness, keeping dogs healthy, not breeding indiscriminately or for money, and doing things right - perhaps it's my auditing background.
As I said, you seem to be doing it right.
To a certain extent I agree about colour in any specific dog, - a good horse is never a bad colour, as they say, but you wouldn't buy a Volkswagen Golf if someone advertised it as a Land Rover, would you? You would realise that they knew very little about either make of car.
Breed standards are fairly explicit for very good reasons! If you didn't adhere to the colour names you would have a great many different names for each colour. For instance I have seen Labradors described as 'Jetblacks; Shaded blacks, Chocoblacks - just silly - they have genes for black or yellow or liver, and that is what they should be described as.
Golden Retrievers are golden, Labrador retrievers are yellow.
Sally, Fox Reds are becoming more popular - they are a variation of the Yellow gene - this is the section from the Kennel Club Breed Standard. They can vary from a dark yellow to a really rich red.
Colour
Wholly black, yellow or liver/chocolate. Yellows range from light cream to red fox. Small white spot on chest permissible.
