Are the door hinge bolts on a 67 gto painted same color of car?

No, the door hinge bolts on a 1967 GTO were typically not painted the same color as the car. They were usually left bare metal (likely a cadmium plating) or possibly a black or dark gray finish, depending on the factory process and any subsequent touch-ups or replacements. The focus of the paint job was on the body panels themselves.
