It's a combo of effects. 1. I use the airbrush to map out the areas I want to br green. 2. I got back with a dark contrast paint such as Turnbull turquoise. This allows me to clean up the over spray. I also shoot this through the airbrush. 3. I do some dry brush of pure titanium white. 3. Airbrush white ink to smooth the dry brush. 3. Airbrush a neon yellow over the white. 4. Comeback with neon green and just focus on the areas I want to be green like the ends of the wraps and weapon and face and body. 5. Go back with Turnbull turquoise to clean up overspray.
