Micas, Pigments, Powders
Micas are a natural product, that is mined but then, the individual mica (which looks like a platelet) is coated with FD&C colorants, or pigments, or a combination of both to achieve the colorant. The dual sided color is what causes the shimmer and sheen of micas. Mica is exactly the same stuff you see in your lipstick, eye shadow and blush. Micas work best in clear products, like clear melt and pour, because the shimmer needs light in order to reflect and refract nicely.
