Wikipedia: Triethylborane is strongly pyrophoric, igniting spontaneously in air, burning with an apple-green flame characteristic for boron compounds. Thus, it must be handled and stored in nitrogen or argon

The Raptor engine does not use TEB (or TEA, for that matter); it's spark ignition. So the only substance around that burns green is the copper which lines the ignition plate. If that's burning, the engine has ceased to be "reusable."

One other note, in addition to low pressure in the methane header tank leading to an oxygen-rich environment looking for something to burn, don't forget that that same methane is used to actively cool the chamber. So you've got hot oxygen and hot copper. Leading to hot green exhaust. //

This test not only demonstrated that most things worked right, it also freed up a parking place for another StarShip.
