White, cream, yellow, fox red are all shades of yellow. Its all a preferance of color. I dont advertise for different shades of yellow. Some reputable breeders do but its mostly the bybs or unethical breeders who advertise for a specific color. Also people who breed for a specific color isnt caring about that dogs particular lines nine times out of ten.
I have a fox red lab He is on my siggy. Its a shade of yellow I really like. But I wont breed my dog just because of his color. He has to prove to me he is of value in the gene pool.
I have noticed that those people who breed for the fox red often loose the black pigment in the process. Breeding a red to a red is ok but you want to somewhere bring back the black so you dont loose the black pigment. Since black is the dominate color for labs.
I would prefer to see a dark yellow or "fox red" bred to a black that carries the red gene. You get a better coat and better pigment.
So the red or dark yellow is ok but a breeder shouldnt "specialize" in that color alone. There are many different things that a breeder should look at which is the same for any reputable breeder. Clearances, pedigrees, performance ect. Those all come first before color. JMO
Heres a better pic of him so you can see the color.
