The Pacemaker Passenger Car Interiors or just heavyweights

I've asked this question on multiple forums with multiple responses from indivduals, but no one can quite remember clearly. The best two respones I've gotten that were heavyweight seats were either a dark green or a medium grey color. The cieling and walls are biege and the floor color is unknown but suspected to match the seats...probably a green color.

Does anyone on this forum know the color of the seats and floor that would have ran on a car like the one in the picture that is prototypical to being on the pacemaker.
