Most of mine have been only het for fee and look greyer. These younger photos do look correctly fee though, so I would say she is het and it's leakage as she ages, though I've never had one develop that much brown myself.
That looks like a standard pharaoh, not a falb fee - do you have other pharaohs not pictured? The brown can vary a bit. And the snowie looks like a golden manchurian, I don't believe she has fee either.
