Rihanna has partnered with MAC Cosmetics to create a variety of color collections--she even put her own spin on their famed Ruby Woo--called "RiRi Woo". She was especially adamant that the color be suitable for every skin tone. 

She said in a statement, "When you think of makeup, the brand that pops into your mind- for something legit - is MAC. I've been using MAC on tour for such a long time it was a natural fit for me. I have always loved makeup, and I always said that if I do it, I want to do it with a credible brand."
