Shiva's Premium Signature Artist Oil Colors offer the richest color intensity, brilliance of hue and chemical purity available to the discerning artist. Richeson Oils are among the highest quality oils on the market.They carry the ACMI approval for health and safety and meet all government ASTM standards. Each pure Shiva pigment is ground to its own correct degree of fineness and then formulated individually under exacting laboratory controls. As printed colors can never truly match their pigments, each Richeson Shiva oil label is hand painted to show exactly what color is in the tube. They are guaranteed to be permanent, free from darkening, yellowing, fading and cracking.
Shiva Signature Oil Colors are made with the finest grade of alkali-refined linseed oil available. This type of oil is well-noted for excellent color stability. "Straw" in color, it has a minimal effect on pigment colorization and will not darken with age. In certain colors, such as the whites, flesh colors, ice blue, and light brilliant yellow, Shiva uses safflower oil. With these sensitive pigments that yellow easily, this oil produces a much better non-yellowing color.
