You are labouring under a misconception. There is more genetic diversity across Africa than there is between African, Asian and European populations. Some of this is reflected in skin colour. In all sub-Saharan African countries there are people with paler skin, particularly east African countries such as Ethiopia. My girlfriend is 100 Camerounian, but pale and would pass as 'mixed race'. I can't guarantee the racial provenance of these girls, but the photos and the girls come from Africa.
