According to FUNKTIONARY

Colorism – the prejudices that Afrikans hold about each other and seemingly use against or to the advantage of themselves and others of relatively similar complexion. 2) skin-tone stratification among melanated people used as a divisive strategy and tactic. Colorism in the cultural context of group power, is an attitude. Colorism is reflected in intra-group interaction— it occurs within a group. In the Euro-cultural context, influence without the perception of a sufficient power base behind it is ignored at best—and invisible at worst—but having the same net effect just the same. The only appreciable difference between racism and colorism is that we discriminate without power. We are guilty of complicity in the deadly power game of world-wide White Racism Supremacy.
