For hundreds of years people have been putting a large about of effort into coloring in bibles. As far as I know the book itself doesn't endorse the practice.
Yeah, I was being a bit tongue-in-cheek. What does it mean for a book to endorse making color illustrations of it's content? Why is the lack of endorsement for color illustrations in the Bible noteworthy when explicit endorsement for illustration is not really something we expect from any book.
