Its pretty close to the pre-heresy world eaters icon anyways. Its not like the heresy kicked off as soon as they changed over from the war hounds.

A lot of their official depictions lean towards gold rather than brass as described, much like the color of blue they use is actually all over the place. If they had a good matching primary brass for veterancy helmets I'd go with brass, but sadly there isn't.
