Interior colors

Hi guys. I’m looking for some information. My 63 interior trim code is 843-Blue Impala SS buckets, paint 914-Monaco blue. I note that my steering wheel is 2 tone blue, but the headliner and sail panels are black star pattern.
Would it be normal for a trim code Blue have a black headliner and black painted dash or did someone paint or replace the headliner and paint the dash? Pls weigh in with all your knowledge. I’m new to Impala restoration.
