@John Wadell. I really want to add a 4th overdye and the appropriate 3 light, medium and dark solids to my already-settled 3 overdyes. These 3 are the vertically placed threads in the 2 photos below. The horizontal threads (3 in the top picture below, 4 in the bottom picture below) are potential candidates. I have spent so much time trying to select the best one that I am totally befuddled. I included the yellow only because it shows as a triad color on the color wheel; not sure I like it. Right now I am leaning towards the Caron #236 Appalachia and #048 Far Horizons, but not sure about them.

Would you kindly look at them and tell me which one really works. Thanks so much.
