A Sudanese model expressed her frustration as a dark-skinned woman in a largely light-skinned fashion industry, via Instagram post.

Nykhor Paul, 25, also called out makeup artists for their ignorance and unwillingness to accommodate diversity with the races and colours, reports Mashable.com.

She has modeled on runways from Balenciaga to Vivienne Westwood.

“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 ... Don’t try and make me feel bad because I am blue black, it’s 2015…,” Paul reacts in Instagram post, according to .

She lists companies from MAC to Make Up For Ever that offer products for diverse skin tones, the agency adds.

“A good makeup artist would come prepare and do there…research before coming to work because often time you know what to expect especially at a show,” Paul explains, though it's unclear if she's targeting a specific individual.

Instead of an apology, Paul expects a real effort on the makeup artists’ side. “Just because you book a few of us doesn’t mean you have the right to make us look rachet,” she writes.

She ends the letter addressing the lack of diverse models on the runway.

“I’m tired of complaining about not getting book as a black model and I’m definitely super tired of apologizing for my blackness! Fashion is art, art is never racist it should be inclusive of all not only white people,” Paul says.

Paul is not the first to point out issues with diversity in the modeling industry. British fashion model Jourdan Dunn has spoken about designers not casting models of color, the Mashable Life Style reports.

More recently, supermodel Naomi Campbell stated that she refuses to quit modeling until the industry starts using models of different skin tones, it adds.
