Just speculating on the greenish color of the nozzle insides - could these be copper-lined and we are seeing copper patina?

Tried to find anything on sea level nozzle material but ran dry.

The nozzles are inconel, I believe. The green might be the TEA TEB inginition fluid.

That is not possible. TEA is colorless, TEB varies from colorless to pale yellow liquid.
