They should be the same as the adult if it's a species paeony but could be different if the parent is a hybrid or cultivar or if it's cross pollinated with another one.
I get a lot of yellows and blotchy oranges from my red P. delavayi.
For me it would be a potting up job but it's a bit of a wait to see what you've got.
I believe tree paeonies and herbaceous ones can be crossed but the very double ones with all petals and no reproductive bits won't
