Congratulations! I just got an airbrush,and I love it. My airbrush class instructor said to use the airbrush colors, but others on this board with more experience may have different opinions. We were told, however, that luster dust can be mixed with lemon extract (or vodka) and sprayed through the airbrush. I tried that yesterday and, OMG, I will never go back to painting on buttercream with a brush!
