I love all the Labs I've met and worked with. But for the dog's safety I prefer a color that stands out against the typical hunting terrain in the area.
So I'd prefer a black or red or choco Lab in places where the main bird hunting may be on snowy backgrounds, or in CA where the usual background is often yellowed dead grass or brown desert soil. In dark green places like the Southeast, a yellow or white Lab would be fine.
Understand that obedience is also a major safety factor, so a good learner is paramount and a more important factor overall than color, for sure. But in over sixty years of bird hunting I have seen what a shotgun does to a good dog, and ANYTHING that avoids that is desirable. If you can't see them, it makes it more likely that you or somebody else might shoot them.
(To me the PURTIEST are the yellow fellows....).
