Looking good, but the interior of hatches that could be see from outside when they were opened, weren't painted white. They were painted in the base exterior base color of the vehicle.

The grey-green color was used for a lot of the lower interior parts of the tank, such as the floor and lower sections of the hull since it was very dirt and oil resistant.

Sometimes sections in the lower hull and in the engine compartments were usually left in the red oxide primer color. Certain components, like radio gear, transmissions, switches, sights, some cabling, and smaller items was left in the color they were from the factory.

Later in the war, for a short time, the entire interior was painted in just the red primer to save time and costs. Crews complained about it vociferously, and it was quickly discontinued.
