In a blog post on Wednesday, Gray said she was "annoyed" but "not surprised" by the limited range.

"This is an issue that plagues any woman who is not white," she said. "Getting anything to suit your skin tone from global beauty brands is almost impossible.

"I, like so many other black women, have to buy high end foundations and concealer because billion-dollar beauty corporations simply don't cater for us.

"They always make the same excuses saying there is no market for the product, which is just not true."
