So, I have a general complaint about colors but I'm not sure if this qualifies as a typo. Color usage doesn't seem to be super consistent in the comics. For example, some people have blue eyes, and sometimes their eyes are just kinda drawn with browns or generally unclear. Obviously if this is a super long perspective shot, I don't expect people's eyes to be drawn, but take a look at Chapter 1, Page 3-5. Sometimes Praxton's eyes are clear light blue, and sometimes it's brown-ish. Again, maybe I'm just being nit-picky.
Similar complaint for the sand master sashes. Sometimes the colors aren't so clear and/or consistent. Especially since brown, tan, and cream are all the same color (kinda), just different hues. In the big meeting of the entire Diem, each rank of sand masters is set out with colored flags indicating their rank. The colors at this meeting are gold, yellow, dark blue, gray? light blue?, brown, tan, cream?. But then in other instances, there's light blue sashes and maybe even a black sash seen.
There's also a clear error with the sashes in Chapter 1, page 2-3, where there's two instances of someone with a green sash. Based on what I infer from the comics and what I read from the prose version, there isn't a rank green sash. Maybe there's some new, unexplained character with a rank indicated by a green sash that isn't explained, but it feels like it's an error.
Someone else pointed this out in some other thread, but Praxton should be bald. He's drawn with hair in Chapter 1, pages 4-5.
