Stopped coloring after 2 months of testing...much happier now! Tried the coconut oil, but in C-3 I don't think it makes a big enough difference to warrant the extra step. I did like the addition of CO in Ecosoya ACB. Other than that trial...no additives. As stated in another reply, vanilla and orange slightly alter the color, but still creamy. One fo I have turns wax grey on burning, but its the fo for sure.
