Lily, how do these various forms of copper compare to one another and to
copper carbonate in terms of the color response they characteristically
produce?

There IS black copper oxide (CuO) and it is pretty black. That is the
one
commonly used. There also is red copper oxide (Cu20) which is a lovely
wine color.
