Early on in our soap making experience we experimented with spices as all natural coloring. We tried several, a couple of teaspoons of cayenne pepper makes the soap a salmon color. Cinnamon gives the soap a beige color. Turmeric makes a coral colored soap and paprika a deep peach. Its interesting working with spices in soap making. Some spices you steep in the base oils then filter them out, some you just add at the beginning of the process and just leave it in the soap. When making these test batches we just used fragrance oils we had left over. We really liked the color of the paprika bar and the only fragrance we had at the time was some peppermint essential oil we had left over from the holidays. Turns out, that by leaving the paprika mixed with the oil the soap comes out with a mild grit very similar to the old Lava soap. Thus the name Pepper Mint Scrub! It's a great exfoliate, cleans oil, grease and paint off your hands with ease!
