Perth Mint bronze coins do indeed often have funky colours, which I haven't seen naturally occur in too many other bronze coin series. And I'm not surprised that the American TPGs have trouble with them; the TPGs can't employ experts in every single series that they grade (even though they are, by virtue of their business, claiming to be just such experts).
I'm left wondering just how many naturally-toned Perth Mint coins have already been submitted by US-based collectors - who wouldn't necessarily know any better - sent back bodybagged and, believing the TPG's verdict, either get thrown away or "treated" to make the toning more "market acceptable".
As for educating them, I don't think there's much you could do as an individual to impress them. Maybe if everyone who's received such a verdict on their Perth Mint coins complained, they might figure it out on their own. Perhaps sending them published articles about the phenomenon from coin magazines and journals would work? Then it's not simply your word against theirs that these colours are "normal".
