Emerald green, a trade name for Paris green, is often called for by coach painters for striping and ornamental work on automobiles and sleighs, but as the ordinary Paris green is not opaque enough to cover, the grade known as pale French Paris green is selected and even this will not be of sufficient hiding power, unless a small percentage of white is mixed with it. Zinc oxide would be least harmful to this pigment of copper arsenite origin, but in order to give it body, white lead is used instead, and the protection of the varnish depended upon to keep the ornaments or stripes from blackening. When intended for striping purposes and to sell as pale emerald green, a grinding of sixty-four parts pale French Paris green, twenty parts dry white lead, twelve parts pale, quick rubbing varnish, three parts raw linseed oil and three parts pure turpentine, will produce 100 parts finished color. Must be ground very fine on a water cooled mill of a size to suit the batch. When desired for glazing over light shades of chrome green in order to enrich these, the pale Paris green must be ground very fine in rubbing or coach varnish without the addition of white and the more translucent the color for this purpose, the more suitable it will be. The proportion of pigment and vehicle in this color should be eight parts by weight of the former to two parts by weight of the latter. Another green for glazing sleigh bodies, etc., consists of verdigris, that is used where a rich blueish green tone is desired instead of the yellow toned effect given by emerald green. For this the purest grade of French distilled verdigris should be selected for the pigment and great care taken to avoid its containing free moisture or vinegar when mixing it with oil or varnish. When mixed and ground fine in a high class rubbing or coach varnish, applied over the proper ground as a glaze and protected by good varnish coatings, it is fairly permanent. Requires sixty parts by weight of pigment and forty parts by weight of vehicle, which should be of the character referred to.

Ultramarine green in japan is rarely, if ever, called for nowadays, as the pigment does not work well and the color is not very attractive. When wanted in quick drying character for coach work, it should be of the deep shade and ground fine in gold size japan of good body, because it tends to harden rather quickly in the containers, due to its composition. If the japan is of the quick type, the vehicle should be tempered by adding some raw linseed oil; sixty-five parts of pigment, thirty-five parts of japan and three parts of oil will produce 100 parts finished color and the grinding should be done in a water cooled stone mill of slow running speed.

Zinc green, cobalt green, green earth, oxide of chromium green and Guignet's green have no standing in the coach color line for various reasons, partly on account of lack of hiding power and partly on account of tendency to scaling and dullness of effect. Green lakes of coal-tar derivative origin are not suitable pigments for coach work, for the reason that so far none have been produced that are not apt to liver when ground in japan or varnish.
