About the color Paris Green

A paint made with arsenic

Paris green is a pigment made from copper and arsenic. Wilhelm Sattler and Friedrich Russ, two paint makers in Schweinfurt, first made it in 1814. They wanted a green that would last longer than Scheele's green, an older arsenic paint that darkened over time. Painters loved the bright result, and it turns up in works by Claude Monet, Paul Gauguin and Vincent van Gogh. Sadly it can turn brown too, and an 1888 test found that watercolors made with it darkened in light and air.

How Paris got into the name

The name comes from its use as a rat poison in the sewers of Paris. In 1867 farmers in Illinois and Indiana found that it killed the Colorado potato beetle. By the 1880s it was the first chemical insecticide in wide use around the world. Planes still sprayed it over Italy, Sardinia and Corsica in 1944 to fight malaria.

Poison on the bookshelf

In the 1800s the pigment was also used on cloth book covers and page edges. Since 2024 several German libraries have kept old books away from readers while they test them for arsenic.

Where the screen code comes from

The Wikipedia article on Paris green shows #50C878 and says it matches the emerald green sample in Maerz and Paul's color book of 1930. Wikipedia flags that source as weak, so treat the code as a guess. Real Paris green looks pale blue green when it is ground fine and deeper when it is coarse. On this site emerald has the same code. Veronese green was another old name for the pigment, but Paolo Veronese green here is a different, bluer color.
