I really hate to be the wet blanket to say this but:
Most "passing" Black and Biracial people back in the day were not Halsey and Pete Wentz colored. A lot of times they were high yellow or light skinned and stayed out of the sun.
I know people want to argue until they're blue but it's true. People down here in New Orleans have pictures of their white-passing/passe blanc grandmothers and they are the same skin tone as Doja cat and Beyonce even.
Today when people say passing it means the public see no signs of negro color and automatically categorise you as white and you're treated as such outside the home. You are unclockable.
It wasn't as cut and dry back then. hell, peoe still argue or what paper bag lite is the official shade of passing. I wish I could cite some sources here to help explain but I'd have to go down a Google hole, also living history and experience should still count for something. So now y'all know if y'all choose to accept it. I don't care either way. I'm just tired of seeing arguments about shot y'all don't understand.
I also will take into account how living in New Orleans means I have a different understanding of color and how my people did things. So I guess apply that filter, as well. We different.
