People often fret when airbrushing multiple colors over a single stencil. In fact, it’s not uncommon for Julia to be asked, “But how do I keep the colors from blending into each other?” That’s a good question with a definite answer, but, in the case of Julia’s Birthday Wishes Prettier Plaques™ set (shown here) and other organic patterns, conscious color commingling shouldn’t be avoided. As you can see in this photo, the blending of two colors in the flowers adds more interest and looks more natural. Julia’s primary rule of thumb when blending water-based airbrush colorings is to know your color wheel. Adjacent colors should be selected to yield a hue that you want in your cookie design. For instance, pink and blue makes purple, which can be pretty, but, avoid green and purple unless you want brown. (Note: Use alcohol-based colorings to minimize blending, and, to avoid overspray into adjacent stencil openings, airbrush very close to the cookie with minimal pullback on the trigger.)
