In olive greens there is a wide divergence as to the effect. There was a time when the color turned out under that name in japan was more like the Brunswick green in the dark shade and similar to Merrimac green in the light shade, but no one would dare to offer these at the present time as olive green. A rich shade of this green and comparatively low for cost, is made by mixing eighteen pounds ivory drop black, thirty-two pounds finest French yellow ocher, five pounds burnt Italian sienna and three pounds medium chrome yellow, with forty-five pounds color grinders' japan, yielding 100 pounds finished color that will find favor for painting automobile bodies or other vehicles. Another shade with more of a greenish effect may be made by mixing twenty-two pounds ivory drop black, thirty pounds French yellow ocher and ten pounds orange chrome yellow with forty pounds color grinders' japan, yielding 100 pounds finished color. These olive greens, on account of consisting in part of French ocher, are best ground on a water cooled buhr stone mill, because esopus stones are too soft and iron mills not well adapted for grinding ocher in japan,
There is still another composite green coach color that has found favor, which we will call fern green. It is to be seen on some automobile bodies and delivery wagons and may be mixed from fifty-five pounds chrome yellow, light, fifteen pounds Dutch pink, four pounds ivory black, two pounds chemically pure chrome green, medium, and twenty-six pounds pale gold size japan, producing 100 pounds finished color.
This color can be ground on any water cooled stone mill, depending upon the size of the batch.
