I was going to say just the other side. If you have a chick (like that "splash" one in the previous page) with SO much white, you are probably going to get a very dark, overmelanized chick. I don't think that chick is a splash, it's an BC that will be completely black if it's a hen (unless it has a white wing feather or two). For me I see more white in chickdown means less copper.
Unless the chick is completely black, or has rusty brown on the face, I find the best BC I am getting are coming from the chicks with the least amount of white in the breast and belly. Instead they are black with gray and a bit of white. Less white in the face is usually better for me too.
Completely black chicks (including legs all the way to the toes) and the brown chicks are definite culls. These are caused by unwanted genes in the mix.
