Hey all, so I am in a tough quandry right now, I am in process of painting up my Imperial Fists army and I need to figure out a way to differentiate the Sargents, veterans and veteran Sargents. currently my color scheme is very simple with iyanden darksun foundation as the primary color, the accent is scab red such as the aquila and others i also use boltgun metal and a couple other colors, but I am keeping it simple. The normal marines have just a darksun helmet, the sargents and veterans have a scab red helmet and I am stuck with the veteran sargents, I am not sure what color or how to differentiate them.
here is a picture of a normal marine, a terminator, and a Sargent or veteran marine.
any advice you can give would be great.
