Blends Very Well
I purchased a sample size of this in the Delicate formula, along with Hannah and thought that I would be blending the two together for my perfect shade. I do, but I have found that I can use either on its own because the minerals blend so well. I actually favor using Calla on its own, even though it is slightly light on my medium skin tone. Callas strong yellow tones go very well with my coloring and it helps even out the redness which makes my face appear darker than the rest of me. I really like how weightless these foundations are and the fresh look they impart. Disclaimer: I have pretty clear skin and am not sure how well the coverage would be for those who have more problematic skin.
