I haven't used modeling chocolate too much, but planned this deer head cake with MC in mind to cover both the antlers (full set) and the deer head (RKT).  I planned on just hand-painting the coloring onto the antlers and head (after adding texture), but it just occurred to me that regular Wilton/AC colors will not stick to the MC!?

Is that right? What should I do? I don't feel like I can get great details with melted chocolate, PLUS, I only have regular dyes to color it with, and that will ruin it! Should I color MC then melt it down and brush?

Yikes :/

AToo paint on MC you should either dry dust or use cocoa butter. In both instances you should use powder colours.

I don't have any experience with adding gel or oil colours to cocoa butter so can't comment on that.

To color chocolate (or candy melts) or to paint on chocolate, you need to use what LisaPeps suggests or oil-based colors. Sometimes they are called candy colors, but just make sure they are oil-based.
