The Next Wave in Text Formatting

Now that physical books are dead, how about we color words to indicate characters you're supposed to remember, ones you aren't, and the same for locations and concepts? Get people used to it first, then the subversion. I think green for memorable characters, blue for locations, and gold for concepts. For the throwaways, brown for characters, purple for locations, and red for concepts. The underlying scheme is that there isn't any and people who can't learn arbitrary rules don't deserve to read.
