I'm three books (and three short stories) into Corey's "The Expanse" series, and I've noticed an interesting trend.
When Corey describes the ethnicity and inherited culture of individual characters to depict a multicultural, multi-ethnic future, he focuses (sometimes in creepy detail) on their skin color and facial features. But while he's got a future full of people descended from Pacific Islanders, Asians, Africans, etc., hardly any individual is described with physical markers I'd consider "white."
I fully embrace an extremely diverse future, but I'm quite sure Corey's not imagining a future where humanity's simply blended out the extremes of physical diversity. I'm told this by his repeated emphasis that Naomi's multi-ethnic features are extremely unusual.
In the TV series based on the books both the main characters and a lot of the background folks are cast with white actors (even the guy with eight parents), but I don't see much indication that's specifically adhering to any sense the book provides for those characters.
Is Corey's future just a largely non-white one, or is something else going on? Am I anticipating a future revelation about the setting or is this just an uncommented bit of subtle worldbuilding?
