What is “colorism”?

From prejudice or discrimination especially within a racial or ethnic group favoring people with lighter skin over those with darker skin. What writer Alice Walker defined as colorism, the preferential or prejudicial treatment of same-race people based on skin color, continues to this day. And as she once wrote, unless we exorcise it “we cannot as a people progress. For colorism, like colonialism, sexism and racism, impedes us.”— Itabari Njeri
