Hi Leslie,
I am not a color expert but the blue skin is normal and is coming from the poodle part of your puppy. I think it may mean that your puppy may 'silver' out as he gets older, but as i said I am not sure. The silver will have a blue tint to it.
I did find this about blue poodles:
"The outer coat of a blue poodle is nearly as dark as that of a black, but their inner coat is a mix of colors. The amount of each color depends on the age of the dog. In middle-aged dog, medium brown predominates. Blues may take several years to "clear" and remain darker than silvers. Many are registered as black."
