Thanks for your comment 🙂 You could add color if you wanted but since this recipe is specifically to heal the skin colorant might inhibit that, but I’m not sure. Mica would add sparkle but not color, ultramarines are “nature identical” but synthetic and I’m not a fan of the other synthetic colorants approved for cosmetic use. You could add alkanet infused oil to give it a maroon hue, but I wouldn’t use alkanet on broken skin like a bite. Colorants are nice for lip balm, makeup, bath bombs and the like but I’m not sure they’d be beneficial in a skincare product specifically made for damaged skin. Hope that helps!
