Don't want to start a rumor, but I believe some models had wooden prop blades, with metal cooler blades. I saw this on discovery's "Wings of the Luftwaffe" " The Butcher Bird" episode. Perhaps this has some relevance to the paint color? Just my .02.

There are a few pics of crashlanded 190`s and there is definitely a visible difference between the bent aluminum propellers and the pulverized wooden ones.

But back to the original question. No, all propellers were supposed to be painted RLM 70 Schwarzgrün ( Blackgreen ) while the Fan blades were painted RLM 66 Schwarzgrau ( Blackgray ) or RLM 22 Schwarz ( black ), sometime they did not have any paint on them tho..same with the lower wings.

It is very hard to be sure from a resored plane as they quite often were repainted completely incorrect ( only recentely did they start to do good jobs as they found more and more complete planes and wrecks in Russia and from the bottom of lakes so they had original painted samples )

Cool! In all honesty the cooling fans will be barely visible in you picture but I've learned an important lesson over the years about drawing. As a general rule the more you know about the subject you are drawing the better you can render it. Even it is irrelevant to the immediate piece it helps you understand and gain confidence. That will usually show in your work.

Wow, amazing illustration skills! :D

supreme draws. save X3

Well, heck, this is the first time I knew the engine had a cooling fan! Ya learn sommat new every day.

Maybe? If the propeller and the fan rotated at different speeds, you wouldn't want the cooling fan to be very visible? (To suppress any visual strobing effects? - Where groundcrew might misjudge the speed of the prop or the cooling fan?)

The cooling fan rotates 5:1 of the main propeller and was necessary since the 190 engine was a air cooled starlike engine.

At/before the beginnig of the war water cooled engines were the main, since nobody thought air cooled ones could bring the needed power - germans showed it is possilbe.

Still - they never solved the problem of the overheating bottom cylinder...

And since the fan is part of the engine i think they came out there in one standard colour.

Another thought on the paint. Near the end of the war, they probably used what was available. even mixing colors just to have enough. But this just my thoughts on it, nothing that's been proven...

I never knew that about the wheels on the FW 190, had to go buy a walk around guide to see what i was missing, an other question did this aircraft have boosted control surfaces, or was that something only the jets had...

If I remember correctly, the BMW engines were delivered as a 'power egg', already fully assembled and ready to mount; the propellors were produced by a different manufacturer. RLM regulations prescribed that the interior of engine compartments were painted in RLM 02, with the exception of the firewall. This was painted RLM 02 on the cockpit side, but left unpainted on the engine side in most cases. All engine support braces, connecting rods and internal framework was also RLM 02 (RLM Grau). Pipelines for fuel, oil and coolant remained unpainted outside of the cockpit areas. Engines remained in the color applied by the manufacturer, usually black. Although not an interior area, propellers are also included in the RLM regulations. Steel prop blades were painted RLM 70 (Schwarzgrün), while wood blades were painted RLM 71 (Dunkelgrün), with a semi gloss clear coat protectant. Other late war wooden prop blades were painted in RLM 84 (Graublau), with the same semi gloss clear coat protectant.
