Yes.
In one of O’Dea’s pics above, one is green, the other silver. I've seen pics elsewhere but can’t put me finger to them right now - however, in terms of evidence, more importantly, of the two preserved ones at least one showed green paint under the BnT.
As mentioned, beasts like these often had long waits to meet paintbrushes, so as can be seen, a disproportionate number skipped the ”green era”, going straight from filth (“silver”!!) to black’n’tan.
Well into BnT days, I saw one so dirty that you could barely see the white line above window level.....
