A bit engine rich at the end?
Some kerolox engine also sent TEA-TEB at shutdown

It looks very uniform for burn-through, the exhaust also seems to be quite low pressure to still be that bright green from copper. Igniter fluid would be my guess.
Which booster has the most soot? SpaceX booster launch history! (discussion)

The green tinged flame is also visible in Firefly's testing of Lightning and Reaver (from which Astra's Rocket 4 engine is derived).

Our first hot fire using the thrust vector control (TVC) system for Rocket 4ís first stage engine. The TVC is the mechanism that allows us to control the direction of the thrust for the rocket used by our Guidance Navigation Control (GNC) systems. #AdAstra
