What color would you call this?

From here it looks just gray.

 

I'll take a stab, Graphite?

 

On my computer monitor, none of the greenish tinge is visible, and barely a hint of the gold. Onscreen it looks like what might be called "gunmetal", "metallic grey", "pewter", or "dark silver".

 

Anthracite.

 

Gun metal gray. Looks like a metal-flake paint job (sparkly).
