Discrimination based on skin tone
Discrimination based on skin tone, also known as colorism, shadeism or pigmentocracy, is a form of prejudice and discrimination in which individuals of the same race receive benefits or disadvantages based on their skin tone. More specifically, colorism is the process of discrimination that marginalizes darker-skinned people over their lighter-skinned counterparts.
