The colour is due to Copper which is a strong coloring agent. Copper chemically combines with the carbonate groups CO3 and hydroxyls OH. Used as a dye for paints and fabrics. Unfortunately its colour is too deep and larger crystals can appear black. Small crystals and crusts show the lighter azure colour well.
