I just bought the silicone shell mold and want to make them in white chocolate. Is there any special color dust I dry paint them with?
I think petal would be good, just shimmer, no real color, unless you want to add an extra layer of color, maybe bronze or a pink would work well too.
I agree with the pink & bronze colors, and also consider purple and a terra-cotta/coral too. Here at Jax Beach there are very few white shells, most have some degree of color. Might try layering with just a light touch and see how you like it.
