I would like to post a site, It had some pictures and some great information on this site. It will clearly show you can have a pure bred lab that is mixed colour and not always solids.... As for reading the laddie page you can fully understand the genetics that go into what colours will be produced! Presley's mom was a black and her dad was a chocolate. There was 11 pups 10 blacks and one yellow!!! BTW If i would have bred Presley to any colour she could have had any colour of puppies as she has all the factors in her...
