I have an assortment of different colors of NM here. Some is silver asphalt/paper. The rest is white, brown, blue, black and the yellow PVC. I have pulled most of the blue, black and brown out because that was the previous owner's work and pretty dodgy. I am sorry I didn't save a piece of each one with the writing on it. I think it was the blue that had the color coded conductor metal. The black wire had copper colored conductor and the white was more of a silver color.
I may have only have 20 - 30 feet of the black. It looked like he bought a small piece to run one circuit.
