I just bought an airbrush and the kit came with a ton of airbrush colors. I am so excited to start experimenting with it but I've heard before that the colors need to be diluted. Do I need to dilute the colors that are specifically made for airbrushing or do I need to dilute only if I were trying to use my gel/paste icing colors? And if so, do I need to dilute with water or should I be using some sort of alcohol or clear vanilla extract???? Somebody please help!

i would love to know too

If they are airbrush colors they should be a liquid and you would not add anything to them to thin them down.

I wouldn't try thinning down gel colors for an airbrush because any clumpy pieces are going to clog the airbrush.

First i trim some of them to draw the thiny line.
I mixed color with volka and test color many times before apply to the cake.Drop fews alcohol on the plate and mixed color slowly until reach your desire . I bought all colors in the Candy store. HTH
