I'm just wondering I have just purchased an airbrush and am very excited and have been experimenting. The first thing I noticed though is that some of the colours are very strong and so I was wondering if you could mix the colours to get a colour that you wanted - or do you spray one colour over another to get the desired shade? I have a bride that wants a burnt orange colour lace stencil sprayed on an ivory background. I would prefer doing 120 cookies not to have to spray twice with different colours (was thinking orange and brown?). But not sure if you can mix and if so do you do it in the airbrush cup or do you pre mix? Thanks in advance.
