Natural umber pigments are still being made, with Cyprus as a prominent source. In the 20th century, natural umber pigments began to be replaced by pigments made with synthetic iron oxide and manganese oxide. The impressionists chose to make their own browns from mixtures of red, yellow, green, blue and other pigments, particularly the new synthetic pigments such as cobalt blue and emerald green that had just been introduced.
Camille Pissarro denounced the "old, dull earth colors" and said he had banned them from his palette. In the second half of the 19th century, the Impressionists rebelled against the use of umber and other earth colors. The Dutch artist Johannes Vermeer used umber to create shadows on whitewashed walls that were warmer and more harmonious than those created with black pigment. Rembrandt used it as an important element of his rich and complex browns, and he also took advantage of its other qualities it dried more quickly than other browns, and therefore he often used it as a ground so he could work more quickly, or mixed it with other pigments to speed up the drying process. It was an important part of the palette of Caravaggio (1571–1610) and Rembrandt (1606–1669). The great age of umber was the baroque period, where it often provided the dark shades in the chiaroscuro (light-dark) style of painting. The umbers were not widely used in Europe before the end of the fifteenth century the Renaissance painter and writer Giorgio Vasari (1511–1574) described them as being rather new in his time. ĭark brown pigments were rarely used in Medieval art artists of that period preferred bright, distinct colors such as red, blue and green. Umber was one of the first pigments used by humans it is found along with carbon black, red and yellow ocher in cave paintings from the Neolithic period. Pigments containing the natural umber earths are typically identified by the Color Index Generic Name, PBr7 (Pigment brown 7). Not all pigments marketed as "umber" contain natural earths some contain synthetic iron and manganese oxides. Commercial umber pigments vary in color depending on their origin and how they are processed. Umber earth pigments contain between five and twenty percent manganese oxide, which accounts for their being a darker and less saturated color than the related earth pigment, sienna. The color of the natural earth depends primarily upon the proportions of iron oxide and manganese in the clay. Umber is not one precise color, but a range of different colors, from medium to dark in value, from greenish to reddish in hue. The word also may be related to the Latin word umbra, meaning "shadow". Umbria is a mountainous region in central Italy where the pigment was originally extracted. Its name derives from terra d'ombra, or earth of Umbria, the Italian name of the pigment. When calcined, the color becomes warmer and it becomes known as burnt umber. In its natural form, it is called raw umber. Umber is a natural brown earth pigment that contains iron oxide and manganese oxide.
