The T-34/85 interior shots I have from
Inside the Great Tanks shows them as off-white, very similar in fact to the German
elfenbein or ivory. You can tell it is ivory and not white because there is a white first aid box mounted on the right hull which contrasts considerably next to the interior color. The gun breach is dark yellow, much like panzer yellow and most of the small fittings such as handles, levers, brake pedals, various brackets, gearshift and steering levers are black. The radio gear, gunsight, (except the headpad, which is black), compressed air tank and vision blocks are olive green. The floor in the driver's compartment is dark gray, the rest of the floor appears to be black. The seats are brown leather. The compressed air lines for the cold weather starter are in medium blue. The handles which raise and lower the vision blocks are dark red.
