I blew out most of the sepia shadows with they yellow, but you can see a bit on the backpack. I was thinking about a sepia weathering wash, so that will probably help. But I've got 75 or so dudes, so I want a quick production process.

Since these guys are all painted white, a wash should get in all the places I miss with the yellow.

So far this guy was primed white, then airbrushed white and grey, then Vallejo Air Yellow, VA Burnt Umber and VA Medium Yellow. I tried brushing on the Minitaire yellow ghost tint, but that's more like a candy.. Made the yellow more orange and didn't give me any shading, plus it is glossy. I did try the Ghost Tint right over the white and grey model and that might work if I hadn't used grey. The tiny didn't cover they grey at all.

I think I'll try to find some light brown shadow and then a darker wash.
