It wouldn't personally for me have been worth coaching the child to refuse because I can't think of a single situation prior to middle school when it ever came up and then only in the form of something like the botany coloring book. I must say I have a bit of envy for a childhood with so few worries or challenges that coloring books would be one of the biggies worth coaching the child about. And, I mean that in a serious way, it is a happy comment on life that this can rank as an issue.
