Chrome Green

Chrome Green

Chrome green, as much as chromium oxide and chromium hydroxide, then also mixtures of Berlin blue and chrome yellow, often with large additions of heavy spar powder, clay, gypsum, etc., such as oil green, cinnabar green, green cinnabar, American green, deciduous, moss, mignonette, myrtle, deck green, silk green, bronze, emerald green, chrome green extract. To produce them, the paste-like pigments are mixed and milled while wet, or moist Berlin blue is stirred into the liquid in which chrome yellow is to be precipitated. These greens cover excellently as oil paint, dry very well and are quite durable. They are less useful as watercolours, but they are used extensively in wallpaper printing.

Due to the high level of toxicity of the lead chromate contained in chrome green, the non-toxic pigment chromium(III) oxide Cr2O3 is generally used today for RAL 6020 »chrome oxide green«, RAL 6031 »bronze green« and comparable shades.
