Painters can also take advantage of the “temperature” shifts of the Hansas –- from coolest yellow (Hansa Yellow Light) to warm golden yellow (Hansa Yellow Deep). Because they are more transparent, Hansa Yellows have great value as glazing colors. Hansa Yellows make more intense tints and cleaner secondaries, especially when mixed with other organic (modern) colors like Phthalo Blue and Green. In their masstones, Hansa Yellows resemble Cadmium Yellows but the similarity ends there. They are organic pigments that are semi-transparent and lightfast (Hansa Yellow Light is Lightfastness II, and Hansa Yellow Medium & Deep are Lightfastness I). Hansa yellow pigments were first made in Germany just before World War I. Because the original pigment is lead based, Robert Gamblin formulated an excellent copy at a reasonable price. ![]() Rubens used this color extensively for skin tones. Contemporary history of this color begins in the 18th century but “Naples Yellow” means more a color than a chemical composition. Assyrian artists used this pigment to make ceramic glaze. In its transparency, it makes a glowing warm yellow-as if a painting were suddenly lit with summer sunshine.Ī color with obscure origins, Naples Yellow was originally lead antimoniate. In the 20th century, the most transparent of the yellows that we at Gamblin call “Indian Yellow” is a light stable diarylide pigment. But Indian Yellow was lost somewhere between the decline of cruelty to animals and the rise of manufactured pigments. Their urine was collected in dirt balls and sold as “pigment.” The resulting artists’ color was a warm transparent glazing yellow. To make Indian Yellow, cows were force fed mango leaves and given no water. Gamboge was used for glazing before Indian Yellow became available in the middle of the 19th century. Occasionally painters found some Gamboge, a strongly colored secretion from trees that resembles amber. In its transparency, it makes a glowing warm yellow-as if a painting were suddenly lit with summer sunshine.īefore the Industrial Revolution, painters used Yellow Ochres or Orpiment (sulfide of arsenic). Indian Yellow has been prized for hundreds of years and is ideally suited for glazing. Hansa Yellows can boost cadmiums in mixes enabling brighter secondaries. Hansa yellows retain their intensity in tints and make beautiful glazes. Painters today can choose from among the cadmium yellows of the impressionists as well as the modern and more transparent hansa yellows. Although more expensive than Chrome Yellow, Cadmium Yellow was used by landscape painters, including Claude Monet, because of its higher chroma and its greater purity of color. Cadmium Yellow replaced toxic chrome (lead) yellows. Today hearing “yellow” many painters will think of Cadmium Yellow – brilliant and opaque. It has the highest reflectivity of any color. These dusk colours are dark granulating colours with a bright undertone.The color yellow appears to advance. Our range of dusk colours offer a more extreme granulating effect. Granulating colours are indicated with a G on the colour chart and packaging. This results in a characteristic grainy effect. The particles of the pigments used in Rembrandt granulating watercolours tend to cluster and collect in the deeper layers of the paper. Controlla le linee guida minicipali locali.
