The timing and color composition depend on the location and atmospheric conditions (ratios of sulfur, water, sodium chloride, carbon dioxide, oxygen, etc.). The colors range from a shiny pinkish red, to brown, black, and eventually to different shades of blue, purple, and green. Although these reactions have all kinds of fancy names like copper oxide, copper dioxide, copper sulfide, copper carbonate, etc., the interesting part is the dramatic change in color throughout the process.

The Statue of Liberty was not always green - through a series of complex reactions, it took over 30 years for her to evolve into her current appearance. It is also referred to as a ‘passive layer’ which protects the statue from further oxidation. This final stage of oxidation is referred to as verdigris, which means ‘Green of Greece’ in Old French.
