I'm having an issue with color contrast. My main colors are 50/50 dawnstone and abadon black, and Trollslayer orange. On the fire warriors the dark grey doesn't contrast against the cloth, which is also dark grey, very well, but all of the orange armor lets it work.
On my pathfinders though, it's just too much, and I don't know how to make it contrast or what is a better color.
First pic is the gun in dark grey:

Any advice or tips?
