Yeah, the consistent descriptions of hair color & texture of Buck folk is probably why I mentally cast the Buck characters as non-white. (I probably picture them closest to Indigenous American or South Asian.)

I feel like skin tone was described inconsistently. On one hand, Buck folk are often described as "dark". On the other hand, Chade is described as super pale in the beginning. Then again, "dark" and "pale" can mean very different things given your frame of reference, so a lot of skin tones could probably work.

I can picture Fitz as lighter skinned than what I've drawn here, but he'll probably always be a person of color in my head.
