Copper is a reddish colored metal with a high electrical and thermal conductivity.  It has its characteristic color because it reflects red and orange light and absorbs other frequencies in the visible spectrum due to its band structure.  It is in the same family as Silver and Gold and is a malleable metal.  It is beautiful natural or polished.
