D&RGW color scheme for buildings?

[Svein]

Does anyone know if the D&RGW used any particular color scheme for their buildings (depots, freight houses and other lineside structures) on the narrow gauge lines in the 20's and 30's? We have found several pics that show a combination of tan and brown (or light and dark in the b/w photos), is this correct?

Thanks,
Svein and Vigdis
