I love the contrast between the fence and the arbor. I think I would vote for the dark reddish color. Otherwise it is just a big clump of the same color. course that makes for an interesting palate for the flowers - no contest with them. Doesn't matter what you do, it will be beautiful. What a tremendous effort this all is. Humbling that I cannot even get my small garden together. But you explained the rationale of each type of planting so it is a planned well thought out effort with an eye to each section's possibilities. Though in some cases you tweaked the site to improve its possibilities. Thanks so much.
