I think silkies hold their color the same as others, but might be diffused a bit when they have the silkie feathers. I had a paint on the left at one point. Now if that paint had satin feathers instead, the dots might be more prominent. The middle is a satin partridge. Still have her. The right guy is long gone to someone's home, but just showing how a frizzle displays the colors.
All of those color charts they have out there aren't breed specific though some may say theirs is.
This post was about Orpingtons, but is exactly the same for silkies and other breeds.
So the breeding for color would be the same, but I do see how some might look differently if they are a different breed.
