Mixing Colours for Airbrushing?

Yes, you can easily mix colors. I like to test my color formula on a few trial cookies first; then I will mix up a larger amount of color (by counting drops) into a clear plastic squeeze bottle with dropper top. The dropper top makes for easy dispensing into the airbrush cup. This way, I have a more consistent color from cookie to cookie when doing large runs, and I only have to mix once (versus many times in the tiny airbrush cup).

Thanks Julia, I was thinking the same thing to do a larger batch of colour mix once I had estrablished the colour as I will be working a large number of cookies. Great to know. Do you know if anyone does pastel type airbrush colours?? The Americolor ones I have all seem so strong? Or is the idea that you just mist lighter to get a lighter shade? Although that does really work it seems?

I work with Chefmaster airbrush colors and they are all quite strong out of the bottle too. But I soften them by adding in their white airbrush coloring, or tone them down (mute them) by adding a touch of brown or black. Same basic color mixing principles as with regular coloring or paint for that matter . . .

You can't regulate hue with the airbrush trigger, just the saturation of the color on the cookie - so, yeah, it's tough to mist lighter and expect to get a true pastel color.

I find it difficult to get a light enough spray on cookies using airbrush colors at their full strength so I dilute the colors with vodka to at least a 1:1 ratio. It makes the color sheer enough that I can get the effects I want and also allows me to build color by spraying an area multiple times.

I also mix my colors ahead of time but I  find that layering different colors adds a lot of dimension to a cookie so you might still want to consider that option.

I'm new to the airbrush too.  In my search of articles to read I came upon this one about adding Ivory to mute colors.  Although the colors they are using are 'regular' frosting colors ... I bet you could apply it to 'air brush' colors too.  http://www.sweetsugarbelle.com/2011/09/amazing-ivory/

Thanks Everyone! Love the idea of adding white or ivory, will try. Thanks again
