I have a follow-up question for you:
I am working on another text that has multiple colors of highlighting (6 so far) that have different purposes. So I need to retain all of them. They do not have shapes or anything else associated with them. I do not think I'll be able to substitute any of the other typeforms for colors since I'm using them all in the text. So I can see two ways of doing this, and I'd love to get your opinion on whether one of these is best, or whether there is another suggestion for 6 or more highlighting colors in a text.
- Use the five TD-typeforms for the first five colors, then use a TD-shape for the other(s), writing a good TN, as you suggested above.
- Use TD-shapes for them all, as suggested above. That way there is consistency for the reader throughout the text. I'm leaning this way, but I wanted your thoughts.
