Green Color Decoration: Mixing two primary colors in equal proportion results in the formation of the secondary colors - orange, violet, and green color decoration. When a primary color is mixed with an adjacent secondary color, a tertiary color - such as red-violet or blue-green color decoration - is produced. Seeing colors as spokes of a wheel enables you to see how one color relates to another.
Among the varieties of chalcedony, carnelian, or sard, is red or brownish-red; chrysoprase, apple-green color decoration; prase, a dull, darker green color decoration; plasma, leek green color decoration or emerald green color decoration; and bloodstone, dark green color decoration with small red spots, like drops of blood. Agate, a chalcedony with delicate parallel bands of color, or irregularly clouded color effects, is white, red, brown, or blue. Moss agate contains mosslike forms caused by oxide of manganese. In onyx, the differently colored bands are straight and parallel. Sardonyx is onyx containing bands of carnelian (sard). |
