Yes, that's possible as it was shown with Giorno. But the question is if what Araki meant with that comment was:

A) Joseph had Hermit Purple in Part 2

or

B) Stand-users see Hamon-users as someone wrapped in Hermit Purple

I personally think that B is more likely, as that would mean that all Hamon-users would have some kind of Hermit Purple. And that is possible, seen that Jonathan's stand is literally Hermit Purple 2
