I would leave them as they are possibly to add a third contrasting colour you could paint the ear plugs and the beads/necklaces armbands either a white or green jade colour, these were often stones or shells and sometimes human or boars teeth. The penis is actually a sheath that they used to cove the old man

so perhaps a different colour for that?
Love the bow conversion too I dont think I would have the patience to string them and certainly not the skill to do it that well
