Using White skin color as the standard, colorism is the allocation of privilege and favor to lighter skin colors and disadvantage to darker skin colors. Colorism operates both within and across racial and ethnic groups. Colorism finds its roots in racism because, without racism, someone’s value and perceived superiority wouldn't be based on the color of their skin.
