I feel like me and the author of this piece have different opinions about where to put the line that separates orange from yellow.
If you showed me many of the posters shown here in isolation, and asked me to describe the palette, I would have said "that's a yellow poster": https://stephenfollows.com/i/171004131/orange-the-mvp-of-the... - with some exceptions such as Lorax and Unbelievers that I would have said are orange.
EDIT: I changed from "most of the posters" to "many of the posters" as there are some that feel to me decidedly orange.
