INCI: CI 42090 (Blue 1) & Castor (Ricinus communis) Oil
Blue darkens, deepens, and makes colors cooler. I was worried about using blue in my lip balms to make mauves and plums (my favorite lip colors), but oh, the color was great! There would be no way to do these fabulous colors without the blue.
Remember, a little goes a long way!
