I need to know where I can buy food coloring for airbrushing rather quickly. I need it within the next couple of days so mail order is out. I live in the pittsburgh area. Does anyone know of any where I can purchase this or if I can make this myself?
You can thin the gel colors with vodka, everclear or a colorless extract like vanilla.
A drop of color to a Tbs should work. You don't want it thick or it could clog the airbrush. Keep it thin like water.
