I got a 255 bright blue deluxe interior in a 67 Firebird convertible.
Personally, I shot it with "bumper" paint to the 255 spec from House of Kolor. Second best $70 I've ever spent. Did the seats, panels, dash pad, kicks, console, speedo bezel, everything, came out awesome... everybody flips its painted. But the real issue is the condition of the interior plastic, seat foam and vinyl. Replace all if necessary, painting is secondary.
Your horizontal dash surface (where the AM speaker grille is centered) is a darker evil mysterious kind of blue, it matches nothing else that I know of. There is no black anywhere except the area surrounding the lens of the speedo/fuel bezel. The door panels have an integrated custom armrest and door release handles. There is also an "oh my god" handle above the glovebox.
