Sure, but you could also have a more useful visual design while maintaining that. The problem with the site, on mobile at least, is the lack of visual hierarchy through spacing, text weight, and implied lines because you might only see one or two red chapter titles on screen at any given time. I get that they were trying to stick with a visual motif and the red text does make the chapter titles stick out— it would work great in print or maybe on a big monitor when you could see it all at once. But if you have to scroll through it, I found it pretty irritating to have no way to visually orient yourself.
