Cocoa Butter. The other stuff is for cakes mostly.

Cocoa butter for chocolate, the other colorings for airbrush contain water and are usually used for decorating fondant. You can also temper your own cocoa butter and add the fat-soluble coloring of your choice

Some of the airbrushing liquids from ChefRubber are for decoration only (i.e. Showpieces) and are not edible. Ditto with the other responses - use colored cocoa butter. It will take a little practice to get the hang of. Call ChefRubber if you aren't sure what you are buying is edible/I edible.Andrea

Thank you all for the quick response
