Speaker cable


Can someone tell me why positive (red) cable is of copper and the return (white) is of whatever? It could be sliver plated, but why is it necessary, what does it add?

thanks

I remember decades ago buying spools of speaker cable at Radio Shack . One leg had a silver look. Strictly to identify + and - . Don't think it's any more than that.
