Is there a nice rich dark brown petal dust or other color (not air brush) to touch up chocolate fondant decorations?
I'm not sure if this will help you or not; I did this wedding cake last December and they wanted chocolate buttercream and I dry brushed it with Mahogany Luster Dust. I'm sure if you used it on fondant it would really pop.
Here's the cake
Jibbies, the cake looks great and I love that color. I'm assuming that the brush is dry when applying luster dust on the buttercream - or airbrushed? Would you need it wet for fondant?
I dry brushed it with one of those brushes that look like a fan, it took a while, but it was worth it.
Here's a cake I did with fondant, the top tier was brushed with white pearl luster dust combined with Everclear.
Everything on the bottom tier started out white. but I mixed each one of the colors with Everclear to achieve the colors. Here's the colors I used. Claret, Super Green, Super Blue, Champagne and Violet. All of my Luster Dusts are CK brand.
BTW I use Satin Ice fondant.
So if you use someting like mahagony on chocolate/brown fondant you would have a very beautiful sheen.
