I don’t think there’s an objective, factual answer to this question, and I’m interested in anecdotes as well as data, so I put it here.
In antebellum America, through Jim Crow, the concept of Blackness was defined by the “one drop rule” - just one drop of black blood was enough to brand a person Black, and subject to bondage or subjugation.
This led to tortured descriptions of “black people”. An Octaroon, for example, was 1/8 black. That means that they had 1 black grandparent.
Homer Plessy, of Plessy v Ferguson fame (that is, a U.S. Supreme Court decision that upheld segregation as “separate but equal”) was an octaroon. He challenged segregation by sitting in the white people section of a train. He wanted to get arrested so as to have a case. The only problem was that he didn’t look black. He had to tell the train porter he wasn’t supposed to be there before he could get arrested.
Sally Hemmings, Thomas Jefferson’s concubine, was the daughter of a white man and a black woman. Her children (from Jefferson) were able to live as white people.
Rashida Jones’ father was Quincy Jones, a black man. Her mother was Peggy Liston, a white blonde woman. Not quite the same combination, but consider her appearance.
I enjoy watching Henry Louis Gate’s genealogy show Who do you think you are? At least 2 celebrities- Joe Manganiello and Ty Burrell - discovered they had black ancestors. Under the 1 drop rule, Mangniello is an octaroon.
With these ridiculous ambiguities even back then, how shocked would we be if we were transported back then to find people we today consider “tan” to instead be slaves!?
What’s your thought on this? How many black people back then wouldn’t look black to our modern eyes?
