I've been working with planes and, at least in the case of radial engines, I still remember how amazed I was the first time I watched a ground test at night : the flames at full power are definitively white with a blueish end ( with the carburator and ignition tuned properly ) and they extended more than half the fuselage!!! ( the plane was a biplane used for cropdusting, with radial engine and one exhaust stub by the right side ) to give you and idea try to find pictures of Hurricanes used as night fighters... they had to add an anti-glare panel just ahead of the cockpit, and the streaking extends beyond the cockpit ...
