Our '59 was originally Dawn Blue and the interior was the slightly metallic beige. The picture on your post looks very much like the original paint. (I found some protected spots of original paint when I removed a front fender.My brother repainted the truck Baltic Blue) The AD series "champane" interior color seems very close.(I also have some original paint left under the dash and behind the vent covers). My dad bought the truck new and it was built in the LA plant.
