While at a family reunion, we had the chance to visit two farmers markets. One was in Salem and the other Roanoke, both in Virginia. We came across a soap seller that had booths at both markets. She had a mixture of GM and non GM soap and colored it all with food coloring. I asked her what kind and she said the kind you buy at the grocery and put in cup cakes! The colors were beautiful and I never thought of using food coloring. What do you think about this?
