My question to community: isn't it too yellow? Maybe to add a bit red color in a mix with yellow? It is tunable really, so I would like to listen suggestions

present color would be OK for a cold engine rich fuel startup. does the color change as engine warms and mixture is leaned?
blue with a pointed white center is optimum

Any kind of visible flame on startup is very unusual unless this is due to overpriming of the engine. A spitfire in good condition will start with less than one turn of the prop. They can throw out quite a bit of smoke though for a couple of seconds. See here, a mk1a:
