If you have not already, you should watch the film "Passing" I believe it is on Netflix. It was based on a short story about the NYC in the 1920s. It centers on 2 women who are "passing" and use their light skin for very different reasons - one to gain access on behalf of her Black friends and family - the other to escape racism and she actually wanted to live as a white woman.

I highly recommend the film for the ethical journey it takes you on.
