In green pigments there is quite a large field and greens really form a most interesting part of the general subject of color grinding, not only in oil for the trade in general, but also for the coach painter and the artist.
Foremost in the line of greens is what we call chrome green, which, however, is known on the other side as Brunswick or royal green, an intimate mixture of chrome yellow and Prussian blue, while what is known to English and Continental painters as chrome green, must be designated here as chromium oxide green or oxide of chromium green. In the oil color lists will be found such names as bronze, bottle, Quaker green, also Paris green and verdigris, and any number of fancy names for green in oil, which are, however, chrome greens, sold under proprietary brands of varying compositions, none of them being mixtures of pure chrome yellow and pure Prussian blue, but more or less extended with barytes or blanc fixe, china clay and sometimes gypsum. In the coach color list we find these mixed chrome greens under such brands as chrome green, brilliant green, coach painters' green, milori green, in shades from extra light to extra dark, and the proprietary names or brands are legion. Then there are such as emerald or Paris green for ornamental and striping. work and ultramarine green. Aside from these are popular brands of composite greens, such as Brewster, bronze, Merrimac, royal, Russian, Siberian green, in which green always predominates, but in which black forms an important part as well, aside from small percentages of other colors. In the lists of artists' colors will be found a fine grade of Paris green, branded as a rule emerald green or Schweinfurt green, while oxide of chromium green will be found under this name or emeraude green, sometimes also labeled Guignet's green, while green earth is branded terre verte or Verona green, also sap green and ultramarine green. Mountain green (malachite) is used very seldom by artists for oil painting. Green cinnabar consists of various mixtures of Prussian blue with zinc yellow or strontium or Guignet's green with a very small portion of strontium or barium yellow. There is very little call for greens in distemper in this country, although some color grinders list bronze green, emerald green, chrome green, terre verte or Verona green, ultramarine green and verte emeraude (oxide of chromium green).
