Archbishop Bruno Heim

Archbishop Bruno Heim was the nearest thing the Papacy got to an Heraldic Authority in modern times (though starngely he was opposed to the creation of such an institution). His own CoA drove a coach and horses through the tincture convention, which is perhaps why he wrote a book defending metal/metal and colour/colour as valid.
