I can’t remember the exact mix, but when I paint blue, green, etc… dollies, I just get the color I want and barely thin the mix. Enough to blend together, but not so watery that it takes 20 layers. This guy was probably only 2-3 layers to get his base blue. I used a brush to apply mix to eyes, nose, mouth and ears then pounced like a crazy person til it was all perfectly blended. Here are two zombie babies I did the same way. What are you making?
