Periodic Table Knit Update: Transition Metals

I'm finishing the Transition Metals. I'm going to fiddle with the Nonmetals and Metalloids/Poor Metals together. Trying to figure out color combinations using existing yarns only. I don't want to buy anything or add another yarn. So far, I was lucky to find reasonably compatible cotton yarns in my stash. Luck is the key word, here. Even though I've read a good deal more color theory than average, strange things happen when I combine yarns......
