In its natural form, it is called raw umber. When heated ([[Calcination|calcinated]]), the color becomes more intense, and then becomes known as burnt umber.

== Criticism ==
Umber is not one precise color, but a range of different colors, from medium to dark, from yellowish to reddish to grayish. The color of the natural earth depends upon the amount of iron oxide and manganese in the clay.<ref name="StClair" /> Umber earth pigments contain between five and twenty percent manganese oxide, which accounts for their being a darker color than yellow ochre or sienna.<ref name=roelofs>{{harvnb|Roelofs|Petillion|2012|p=30}}</ref> Commercial colors vary depending upon the manufacturer or the color list. Not all umber pigments contain natural earths; some contain synthetic iron and manganese oxide, indicated on the label. Pigments containing the natural umber earths indicate them on the label as PBr7 (Pigment brown 7), following the [[Colour Index International]] system.

==History==
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.<ref name="StClair" />

Dark brown pigments were rarely used in [[Medieval art]]; artists of that period preferred bright, distinct colors such as red, blue and green.{{Sfn|St. Clair|2016|p=237}} 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.<ref>{{harvnb|Thompson|1956|pp=88–89}}</ref>

The great age of umber was the ''baroque'' period, where it often provided the dark shades in the [[chiaroscuro]] (light-dark) style of painting. It was an important part of the palette of [[Caravaggio]] (1571–1610) and [[Rembrandt]] (1606–1669).<ref name="StClair" /> 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.<ref>{{cite web |url=http://www.webexhibits.org/pigments/indiv/overview/umber.html |publisher=WebExhibits |work=Pigments through the Ages |title=Umber}}</ref> The Dutch artist [[Johannes Vermeer]] used umber to create shadows on [[Whitewash|whitewashed]] walls that were [[Warm color|warmer]] and more harmonious than those created with black pigment.

In the second half of the 19th century, the [[Impressionists]] rebelled against the use of umber and other earth colors. [[Camille Pissarro]] denounced the "old, dull earth colors" and said he had banned them from his palette.<ref>{{cite web |url=http://www.webexhibits.org/pigments/intro/industrialization.html |publisher=WebExhibits |work=Pigments through the ages |title=Industrialization}}</ref>{{Sfn|St. Clair|2016|p=237}} 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 [[Shades of green|emerald green]] that had just been introduced.{{Sfn|St. Clair|2016|p=237}}

In the 20th century, natural umber pigments began to be replaced by pigments made with synthetic iron oxide and manganese oxide. Natural umber pigments are still being made, with [[Cyprus]] as a prominent source. Pigments containing the natural earths are labeled as PBr7, or Brown pigment 7.

Jules Bastien-Lepage, Pas Meche, 1882. An example of the shadows created by using umber in a painting.[2]

Umber is a natural earth pigment consisting of iron oxide and manganese oxide; it has a brownish color that can vary among shades of yellow, red, and green.[3]: 39  Umber is considered one of the oldest pigments known to humans, first seen in Ajanta Caves in 200 BC – 600 AD.[4]: 378  Umber's advantages are its highly versatile color, warm tone, and quick drying abilities.[5]: 148–49  While some sources indicate that umber's name comes from its geographic origin in Umbria, other scholars suggest that it derives from the Latin word umbra, which means "shadow".[6]: 250  The belief that its name derives from the word for shadow is fitting, as the color helps create shadows.[6]: 250  The color is primarily produced in Cyprus.[6]: 250  Umber is typically mined from open pits or underground mines and ground into a fine powder that is washed to remove impurities.[7] In the 20th century, the rise of synthetic dyes decreased the demand for natural pigments such as umber.[citation needed]

History

[edit]

The earliest documented uses of umber date from between 200 BC and 600 AD during the neolithic period in the Ajanta Caves found in India.[4] Ocher, a family of earth pigments which includes umber, has been identified in the caves of Altamira in Spain and the Lascaux Cave in France.[6]: 251  Some sources indicate that umber was not frequently used in medieval art because of its emphasis on bright and vivid colors.[8]: 166  Other sources indicate, however, that umber was used in the Middle Ages to create different shades of brown, most often seen for skin tones.[9] Umber's use in Europe increased in the late 15th century.[8]: 168  Umber became more popular during the Renaissance when its versatility, earthy appearance, availability, and inexpensiveness were recognized.[6]: 251 

Reproduction of Lascaux cave paintings, which are around 17,000 years old.[2]

Umber gained widespread popularity in Dutch landscape painting in the eighteenth century.[4]: 378  Artists recognized the value of umber's high stability, inertness, and drying abilities.[5]: 148–49  It became a standard color within eighteenth-century palettes throughout Europe.[4]: 378  Umber's popularity grew during the Baroque period with the rise of the chiaroscuro style.[citation needed] Umber allowed painters to create an intense light and dark contrast.[citation needed] Underpainting was another popular technique for painting that used umber as a base color.[10] Umber was valuable in deploying this technique, creating a range of earth like tones with various layering of color.[citation needed]  

Toward the end of the 19th century, the Impressionist movement started to use cheaper and more readily available synthetic dyes and reject natural pigments like umber to create mixed hues of brown.[citation needed] 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.[6] In the 20th century, natural umber pigments began to be replaced by pigments made with synthetic iron oxide and manganese oxide.[citation needed]

Criticism

[edit]

Beginning in the 17th century, umber was increasingly criticized within the art community. British painter Edward Norgate, prominent with British royalty and aristocracy, called umber "a foul and greasy color."[3]: 56  In the 18th century, Spanish painter Antonio Palomino called umber "very false."[3]: 56  Jan Blockx, a Belgian painter, opined, "umber should not appear on the palette of the conscientious painter."[3]: 56 

Visual properties

[edit]

Umber is a natural brown pigment extracted from clay containing iron, manganese, and hydroxides.[11] Umber has diverse hues, ranging from yellow-brown to reddish-brown and even green-brown. The color shade varies depending on the proportions of the components. When heated, umber becomes a more intense color and can look almost black. Burnt umber is produced by calcining the raw version.[citation needed] The raw form of umber is typically used for ceramics because it is less expensive.[12]

These warm and earthy tones make it a valuable and versatile pigment for oil painting and other artwork.[12] Umber's high opacity and reactivity of light allow the pigment to have strong hiding power.[13] It is insoluble in water, resistant to alkalis and weak acids, and non-reactive with cement, solvents, oils, and most resins.[12] Umber is known for its stability.[5]: 149 

Notable occurrences

Umber became widely used throughout the Renaissance period for oil paintings.[15] In the Mona Lisa, Leonardo da Vinci used umber for the brown tones throughout his subject’s hair and clothing.[14] Da Vinci also extensively used umber in his painting the Last Supper to create shadows and outlines of the figures.[16] Throughout the Baroque period, many renowned painters used umber.[citation needed]

Burnt umber is made by heating raw umber, which dehydrates the iron oxides and changes them partially to the more reddish hematite. It is used for both oil and water color paint.[17]

The first recorded use of burnt umber as a color name in English was in 1650.[18]
