I have a lot to learn and also another factor I have to take into concideration is the reaction with different woods. Some of the colours I use which arn't airbrush paints can change colour just by being sprayed onto different woods. I did a cherry vase with a textured ring around the top and then coloured this blue and once applied it turned green. I like the the uncertainty of working like this but at the same time can be a little frustrating when you are after a clour to be what you want.
