Kenyan model Olivia Sang wants to empower women of all skin tones.

She tells BBC Africa’s One Minute Stories about how she hopes to challenge what is known as colourism, in the fashion industry.

Colourism is prejudice against people who have a darker skin tone - and/or the preferential treatment of those who are of the same race but lighter-skinned.
