98% of the halimos in that app are apparently "light skinned". Just saw the first dark brown one now since I joined. They are becoming mythical creatures in Somali community.
I used to get confused when I attend Somali events and be greeted by a Halima who literally had a bath on lightening stuff and looks very very different and weird to the one I knew from uni and the neighbourhood. They think we Somali men fancy light-skinned women and they became albinos.
