copper greens

LITCopper colours a flame green. Neutral copper's strong visible lines include 510.554, 515.324 and 521.820 nm (NIST Handbook), although much of a real copper flame's colour comes from molecular bands such as CuCl and CuOH. Verdigris is copper acetate, the green-blue corrosion of copper. Malachite is the copper carbonate hydroxide Cu₂CO₃(OH)₂, banded in concentric growth rings.

COMPUTEDThe flame colour is the CIE mix of the three atomic lines only; the molecular bands are omitted (MODEL). The malachite grows ring by ring from an orange copper-oxide seed through a thin purple (bornite-like, INVENTED) shell into green bands, then void.
