Looks like Daddy is a shaded cream (the black hairs in his ears) and the babies are shaded creams as well. Cream babies for the most part are always born dark and lighten as they get older. There's only one way that they would be born light and that's if the 'e' gene is involved. The 'e' gene masks all black hairs making them look cream from day one.
Beautiful pups! Congrats!
