I just started using the Clay 2 stick foundation and I love it. I hafe oily skin so it's a perfect formulation for me. The color is spot on. When I did wear MAC, C7 was the best match. I was matched at NC50 as well but that didn't work out so I stopped using the MAC foundations all togehter. Give it a try. My friend also tried Iman but the color she got was too light so she uses it as an eyeshadow base.
