I prefer natural colorants over micas when coloring my soaps. They often contain antioxidants and other natural compounds that are good for the skin. Some argue that a soap doesn't stay on the body long enough to make a difference, but I believe it stays on long enough.
Here I'm using indigo "ink" made with indigo powder (indigofera tinctoria) for blue and cocoa powder for brown. The color depends on the amount of powder used in the batter, and the final color may actually come out darker, depending on how much you use. I usually start with 1 tsp per pound of batter and go from there.
