Close examination of a colour photograph of a Saturn V liftoff will show
the exhaust to have a brown colouration immediately below the S1C
nozzles, which is a little longer than the nozzles themselves, and just
before the brilliant white flame starts.  This "brown"(?) exhaust is
also apparent on close-up film footage of the liftoff (good example in
the For All Mankind movie) as the rocket nozzles pass the camera.  I
assume this is the exhaust from the burnt Kerosene, anyone else know
better or more? LH2/LOX exhaust would, I assume, be colourless or
blue/white (as on Shuttle's SSMEs).
