Brown paper bag test
"The brown paper bag test" is a term in African-American oral history used to describe a colorist discriminatory practice within the African-American community in the 20th century, in which an individual's skin tone is compared to the color of a brown paper bag. The test was used to determine what privileges an individual could have; only those with a skin color that matched or was lighter than a brown paper bag were allowed admission or membership privileges. The test was believed by many to be used in the 20th century by many African-American social institutions such as sororities, fraternities, and social clubs.
The term is also used in reference to larger issues of class and social stratification and colorism within the African-American population. People were barred from having access to several public spaces and resources because of their darker complexion. The test was used at the entrance to social functions wherein a brown paper bag was stuck at the door and anyone who was darker than the bag was denied entry.
