Very nice, Krayzikk!  That said, I have three recommendations.  The first is putting an extra space between each section, just so that they're even easier to differentiate from one another.  Second, we have three other characters whose colors are shades of gray; in factor, steel gray and gunmetal gray are practically the same thing, so I'd recommend something else.  The last is Ben's name, which doesn't seem to me to be evocative of either color or theme.  Something about RWBY that makes it interesting is its entire convention of names.  Sure, RWBY has a few ordinary names thrown in there (Nora, Blake), but if at all possible I urge you to reconsider.  Since Deinamig means 'dynamic' in Welsh, for instance, you might find the Welsh words for colors and use one of them.  Just an idea.
