Not always . Guys don't throw around claims with no sources. Standards of beauty are dictated by those in power. I do know that in Somalia skin colour wasn't as important as your qabiil because reer xamar's weren't seen as superior. However now colourism /shadeism is becoming huge. Girls put white powder on their face for makeup during wedding ceremonies. It's ridiculous. White supremacist notions are global.
Lightskin has pretty much always been the benchmark for female beauty in all cultures not just ours. As for us males, skin tone doesn't matter at all.
