Differentiation in book textures put into chiseled bookshelves

It would be lovely if the texture of the book put into a chiseled bookshelf would vary depending on the type of book, e.g. enchanted books would always have the same colour, no matter in which slot they're put, written books have a different colour, the same with simple books etc., so that if I have a part of library filled with enchanted books, its actually visible without taking the books out.
