Article: Beyoncé's lighter skin color and costuming has drawn criticism from some in the African-American community. Emmett Price, a professor of music at Northeastern University, wrote in 2007, that he thinks race plays a role in many of these criticisms, saying white celebrities who dress similarly do not attract as many comments. In 2008, L'Oréal was accused of whitening her skin in their Feria hair color advertisements, responding that "it is categorically untrue", and in 2013, Beyoncé herself criticized H&M for their proposed "retouching" of promotional images of her, and according to Vogue requested that only "natural pictures be used".
