A Fixture
It's so difficult to tell with any certainty. My inclination would be that everything is in blackened leather, with metal ornaments in silver. Black leather will take on a reddish brown tinge with wear, but given that this harness is based on a Mameluke or Arabian design, the use of reddish Moroccan leather could well be possible (see the cross-belt for the ammo pouch, for example). The fringes certainly look grey but I think this is just by virtue of the highlights used by the artist. They could, of course, by silver wire, although I've never seen this myself Your call based on best guess and the views of the PF community!.
