I would think that you are correct.My guess would be 120/208. There is no orange wire for a stinger, and 277/480 often uses other color conductors.
But that is a guess only, as I don't see a voltage label (didn't zoom in). I'm not ware of anything in the NEC that requires a voltage label for every panelboard, although I'm not sure I didn't overlook something.I would think that you are correct.

Excellent pointYou should never rely on colors, there are the idiots who use green as a hot/ungrounded conductor, always test.
