The color scheme actually came from Gears of War (since wretches are basically genestealers anyway). But while I was painting them, I decided they needed me to increase the contrast between the different areas, increase the saturation a bit, and not to put a coat of grime over the whole thing. In the end, they didn't end up looking much like wretches at all.
Maybe if I had put a coat of grime over the camera and took photos in sepia...
