Highlighting with washes.

I did up my Pan Oceania starter box with an experiment. I got a bottle of matte medium and used it to make my own washes on the fly. I used Reaper triads, using the lightest color as the base coat, and then did a wash of the medium color, and a second wash in the darkest color.

Not bad results. Fast and easy. The Orc trooper on the left was done with more traditional layering, which is why he looks a bit darker than the others.
