+1 Colorful idea.

While not the same, I combined the predefined colors for the section A & B part markers with the bar based section letter option and was able to create the mock song below in less than a minute.

While I just used A & B part markers I easily could have extended the idea to incorporate more colors by using additional part marker pairs (C & D, E & F, and so on all the way to Y & Z). Also, if I didn't want to incorporate additional styles then when creating the additional part markers select the same style over and over.

Leave the chords blank and save the part marker, bar section letters as a blank chords song for use as a template.
