A compelling doctrinal approach to the Book of Mormon with corresponding color markings of its doctrines and principles so they are ever present for study-review or teaching.
This seems like a very cool way to mark and learn scriptures, but I think you'd have to keep a key in your Book of Mormon to remind you what color means what. Eventually I think it would become automatic though. I might try this. I like that you don't color the whole scripture... Aside from the marking technique it has some good insights about why scripture study is so important.
