95. Verdigris Color 988 - #43B3AE

Verdigris is the common name for a green pigment obtained through the application of acetic acid to copper plates or the natural patina formed when copper, brass or bronze is weathered and exposed to air or seawater over a period of time. It is usually a basic copper carbonate, but near the sea will be a basic copper chloride. If acetic acid is present at the time of weathering, it may consist of copper (II) acetate.

The name verdigris comes from the Middle English vertegrez, from the Old French verte grez, an alteration of vert-de-Grèce ("green of Greece"). The modern French spelling of this word is vert-de-gris. Since it was used as a pigment in paintings and other art objects (as green color), it was required by artists in Greece. It was originally made by hanging copper plates over hot vinegar in a sealed pot until a green crust formed on the copper.
