Braunschweigisches green is a very dark green, almost black appearing metal color on the base of the tetrahydrate of the basic dicopper ( II) chloridtrihydroxid and in contrast to the previously common vegetable-based inks, considerably light and weather resistant than this. In nature there is dicopper ( II) chloridtrihydroxid ( CuCl2 · 3 Cu ( OH) 2 ) in the form of the mineral Atacamit, which itself is of an intense, dark green.

The color took place in the 18th and 19th centuries due to their high quality rapid spread and eventually became established in many countries generic term for this type of green.
