I like my stories to be diverse in terms of race and sexuality, but I find choosing the ethnicities rather challenging. I quite liked the idea of making a main character ethnically ambiguous so the reader could potentially see themselves in the character more. However, if the character comes from privilege and prestige I don't know if it makes more sense to give the character fair skin and hair as those are associated with beauty standards in various cultures, which goes hand in hand with privilege. I also considered the idea of making the less privileged characters, often scrappy, good-natured characters from more challenging upbringings non-white, but I don't want to reinforce stereotypes. I'd like to do the opposite: provide positive role models. So here's the question: how did you choose your character ethnicities? Were they random, or did you adhere to real-world ideas about nationality, ethnicity and culture?
