South Sudanese model, Nykhor Paul, has finally reached her limit: she’s tired of makeup artists being unprepared to work on dark skin tones. The model took to Instagram yesterday to express her frustrations with racism in the industry, calling out “white people in the fashion world.”

“Why do I have to bring my own makeup to a professional show when all the other white girls don’t have to do anything but show up WTF,” Paul writes. “Don’t try to make me feel bad because I am blue black.”

She adds that many makeup brands carry shades for her (including MAC, Bobbi Brown and Iman Cosmetics) but is unhappy that makeup artists aren’t keeping it in their kit. “A good makeup artist would come prepared and do their research before coming to work because often time you know what to expect especially at a show! Stop apologizing it’s insulting and disrespectful to me and my race it doesn’t help, seriously!”

Paul has been modeling since 2008 and has landed major runway shows like John Galliano and Vivienne Westwood (and just walked in the Ilja Fall 2015 Couture show in Paris) as well as magazine covers, having recently been featured on Elle South Africa’s May issue.

Paul is known to be outspoken for causes that she cares deeply about, like her foundation, We Are Nilotic, which promotes peace to tribes in the South Sudan (and even earned her a’s Humanitarian Award nomination this spring). And now she wants to help change the ways the modeling industry in major markets — “plus everywhere else that have issues with black skin tones” — operates.

“Fashion is art, art is never racist it should be inclusive of all not only white people,” she writes.
