My '54 GMC Deluxe 1-ton Panel has a two-tone tan and brown interior - most of the metal was tan, but the seat, gauge surrounds, headliner and interior trim were brown. I would assume that the door panels would have also been brown, but the truck has the optional woodgrain door panels (that are a bit faded after 50 years - not sure if they are salvageable). If the steering wheel was painted, it wore off many years ago.
Hope this helps.
