The colors seem ok, I don't know much about that. We currently use

|books =

in the Dragon Infobox. If that appears within the infobox then it uses the book format, if it doesn't it defaults to the franchise format. Your suggestion seems more intuitive though. How about the word source?

|source = books

|source = franchise

That's a word we can use in multiple infoboxes so it could become a standard across the whole wiki.
