Prime Details could be a toggleable metallic swaps. I like to have Gold Details on any of my primed items or their equivalents, often using the accents color slot as an orokin gold. Only problem is rhino uses the accent color for iron skin too and I don't like being solid gold, so often I am forced to rely on accessories.

Unsure from the pictures, but is the Accent Color Slot Metallic at all even?
