Lo, on the 8/6/2020, Snidely did proclaim ...
JF Mezei asserted that:

However, in the landing video from within the engine cavity, one sees a
lot of yellow flanes starting as it nears the ground. Is this because
below a certain thrust level, the egines are less efficient? or is the
yellow just imporities near ground that are buened by the clean output
of engines?


There was also yellow in the brief external camera shot. But ISTR that
Falcon 9 stage 1 return and landing burns look similar, as the slipstream
pushes the flames up and around the stage.

Still, while it unequivocally proved that SpaceX is on the right track,
both the lead-up to Starship SN5’s hop and the hop itself hint that a
few kinks will still need to be worked out. Notably, during SN5’s hop,
part of Raptor engine SN27 appeared to catch fire at some point after
ignition, producing substantial flames that lasted for at least 10
seconds. For any rocket engine, an onboard fire is always a
possibility, but most engines are either designed to tolerate the
inhospitable environment they create or heavily insulated from it.

which discusses that SN5 may fly again, and that SN6 is expected to fly
despite the progress SN8 is making.
