Shading

Shading.  Engraving lines on a metallic surface to indicate texture or color. The width of the lines and their spacing is critical to effect the shaded appearance. Shading in the field of a numismatic or medallic item is termed texture. The direction of the shaded lines indicate color in heraldic design: vertical lines indicate red, horizontal blue, descending diagonal green, ascending diagonal purple and crosshatch indicates black. These are called tinctures in blazoning (describing coats of arms). Shading is a widely used technique of copperplate or banknote flat engraving, adopted somewhat to die engraving.  See heraldry.
