Brunswick green , also known as Brunswick green , is a painting and painting color that, from 1767 onwards, was manufactured and sold by the brothers Johann Heinrich and Christoph Julius Gravenhorst in Brunswick for the first time in great purity and quantity.

description

Brunswick green is a deep dark green, almost black metal color based on the tetrahydrate of the basic dicopper (II) chloride trihydroxide and, in contrast to the previously used plant-based colors, considerably more light and weather-resistant than these. In nature, dicopper (II) chloride trihydroxide (CuCl ₂  · 3 Cu (OH) ₂ ) is found in the form of the mineral atacamite , which itself is an intense, dark green.

Due to its high quality, the color quickly spread in the 18th and 19th centuries and eventually became the generic term for this type of green in numerous countries . In the Anglo-American language area, “Brunswick Green” (English for “Braunschweigisches Grün”) forms the basis of the “ British Racing Green ” and thus found its way into the Encyclopedia Americana .

A painter's and paintable color similar to Brunswick green is Peinsches Grün , developed by the chemist Pabytzky in Peine around 1768 .
