Hello there,
since I do not have any airbrush equipment at the moment, I used a brush for coloring the moulds. But the result was really, really bad in combination with Roxy & Rich pre-colored cocoa butter. The coca butter was correctly tempered and in the end I used my finger to paint the moulds.
Is this a problem with my brush or my cocoa butter? I used it at 28°C. All the other colors posed the same problem in the moulds. In a tutorial I watched the person painted all the moulds with a brush and the coca butter was sticking very nicely to the mould and covered it quite good unlike the translucant result I got below.
As you can see the tempering should not have been the problem, since they come out very shiny.
