Like it was already said, both parents contribute. If you breed to a darker normal your pastels will feel the affect, if you breed to lighter normals, same thing.
IMO give her a little time to shed and grow up. You said she's six months old? I've got a girl that is about that age and every time she sheds I'm happier and happier that I picked her up. I got her for a really decent price at the Tinley show, I was happy with her, she was a decent graziani, but now I'm totally in love with her.
