does any one know what color i could use to make felch color for the face and othe parts?

I actually have a "fleshtone" airbrush color, but unless you spray it VERY lightly it is more of a copper tone. In a pinch I believe you could get the same effect using brown sprayed in a very fine mist, possibly going back and putting a pink or peach overspray on top if needed. You might even be able to custom mix a skin tone from colors you already have. Count the # of drops you use of each color. If you find a combination that works for you, you will be able to mix up as needed!
