Hi Bob, I notice that the positive electrode always turns black for a short time, maybe a few minutes, before turning gray, while the layers build up on the surface. I've always assumed it was an optical effect of the sub-microscopic roughness of the silver surface as atoms are sputtered off.
After a time, the positive electrode turns a dark gray, while the negative electrode builds up it's usual fluffy gray stuff. Is that what you see? Mike D.
