1. Colorism:

Discrimination based on skin complexion,
society light skin vs dark skin aka house negro and the field negro. Those with lighter complexions are often saw as being safer, less threatening, more attractive, more intelligent. Simply because their complexion is closer to that of a Caucasian.

2.Competitive Nature:

Often when people of color see another person of color doing well, instead of us congratulating him we hate, or become envious. We become insulted that they may have or appear to be surpassing us and want to knock them off their hustle. This is a direct result of us being paired against each other during slavery.
