Which armors/helmets could use new skins?

I’m a big fan of customization, but don’t like all of the available color schemes on armors and helmets. Particularly the ones with white on them. It also seems like the secondary colors usually get very little surface area.
Which helmets/armors do you want new skins for? I’d want one for the Engineer helmet and Noble Valor armor because that’s what I currently like most.
And why not guns while we’re at it? I’m not the kind of guy who wants to run into battle with a lima bean (green SMG). Arctic/urban/etc camos would be very cool additions, or just less flamboyant but still cool skins.
