I was a bit worried when I read that the soap discolored slightly, so I used oxides for the base and titanium dioxide for a hint of white swirls. The white portion has not discolored. I love the fragrance, and after a month it has held true. There were no issues with acceleration or ricing working at room temperature and a slow moving formula. So, I wouldn't be afraid to try this one it worked out for me with the use of mineral pigments.
