RLM 70 was a very dark color that often appears black in b&w photographs. It was called black green for a reason. The propeller looks like it's moving, judgeing by the fuzziness of the blade tips, so the blades might look brighter than they actually were, which would make the spinner painted RLM 23 red or another of the marking colours like RLM 24 blue or RLM 25 green. The fuselage could also be painted RLM 70, but black is definitely an option.
