This is my sincere belief. You are free to not believe it is.
This is getting a bit silly, but:
While the above is generically true, given "color" is a placeholder for a set of possible escapes of which "31m" is a specific example, it is not true that $'\001anyrandomstring\002' in readline is accomplished via %F{anything} in zsh.
