1/3 Black/ Farbton70 and White Spinner on 109s

Not to mention, the engine was LOUD.

The theory that it was so you could tell whether or not the engine was running before you approached is a bit far fetched. Even at low speed, it is pretty obvious when the engine is running and the props are turning.

I do not know of any casualty reports showing ground crew who were constantly/accidently walking into spinning propellers, and as a result needed to paint them to save lives?

You would either have to be deaf or blind to run into one accidentally.

Some spinners did have yellow segments and even yellow tips/caps
