What great colors to wear on a dreary, gray winter day! This is a Schoeller and Stahl yarn called "Limbo Color" -- it's one of those self-patterning yarns, but you can also get creative with it and make a scarf out of color-blended small squares. This way, each square has the pattern of a graduated blend, and every square is different. Makes a gorgeous scarf. I want one, but I don't knit! Carol carries this yarn at her store in downtown Helena.
Here are a couple photos of the scarf squares, closeup:
