Patti, your quilt is going to be a stunner - and no one is going to notice that border of reversed tris other than perhaps another quilter who has made it, then I bet she would understand anyway.
Wil, I think I go along with the concensus that darker, matched scallops will look best in your case - if you have enough fabric, I think matching them would be better than mixing them. You can always use that seam as part of your quilting in those between tris, which will help disguise it.
You are all doing so well, I'm so pleased you all persevered.
