Or maybe I should call it Foxglove Tango? It's a Foxglove construction knitted with Bearfoot by Mountain Colors, in the colorway "Mountain Tango." I used the Master Numbers and decided I'd make increases one stitch from each edge on the sole stitches, making it look much like a traditional sock construction. Markers were not necessary. I didn't fiddle with Cat's numbers at all, and this socks fits perfectly. The second sock is under way, no SSS on this pair.
