Was trying to find documentation of 2 tone interiors. It eludes me right now. Jim Carter was first I saw to address it but now Chevy Duty does also. Headliner is painted light blue on mine to match lighter shade. Vent window trim is chrome, Mine has no arm rests but I can't say that one hasn't been removed when seats and door panels were recovered in the 60s. Even the horn button has blue paint instead of the black to match steering wheel and collar in the darker shade.
