Venetian red is a light and warm (somewhat unsaturated) pigment that is a darker shade of red. The composition of Venetian red changed over time. Originally it consisted of natural ferric oxide (Fe2O3, partially hydrated) obtained from the red hematite. Modern versions are frequently made with synthetic red iron oxide produced via calcination of green vitriol (a.k.a. copperas) [2] mixed with white chalk. The pigment contains up to 50% of the ferric oxide. [3]
Historically, Venetian red was a red earth color often used in Italian Renaissance paintings. It was also called sinopia because the best-quality pigment came from the port of Sinop in northern Turkey. It was the major ingredient in the pigment called cinabrese, described by the 15th-century Italian painter and writer Cennino Cennini in his handbook on painting, Il libro dell'arte. Cennini recommended mixing Venetian red with lime white, in proportions of two to one, to paint the skin tones of faces, hands and nudes. [4]
During the English Civil War (1642–1651), Venetian red was adopted as the primary uniform colour of the New Model Army, to ease mutual identification on the battlefield. In addition, Venetian red was cheaper than other dyes at the time. Following the war, this practice was continued by the British Army, giving its soldiers the nickname "Redcoats", during the 18th and 19th centuries. Venetian red was replaced as the main colour of British Army battledress by khaki, during the 1890s. [5]
The first recorded use of Venetian red as a color name in English was in 1753. [6] There are many other names for the iron oxide red pigments of different shades, with Spanish red being very similar. [2]
Sienna is an earth pigment containing iron oxide and manganese oxide. In its natural state, it is yellowish brown, and it is called raw sienna. When heated, it becomes a reddish brown, and it is called burnt sienna. It takes its name from the city-state of Siena, where it was produced more widely during the Renaissance. Along with ochre and umber, it was one of the first pigments to be used by humans, and is found in many cave paintings. Since the Renaissance, it has been one of the brown pigments most widely used by artists.
Tempera, also known as egg tempera, is a permanent, fast-drying painting medium consisting of pigments mixed with a water-soluble binder medium, usually glutinous material such as egg yolk. Tempera also refers to the paintings done in this medium. Tempera paintings are very long-lasting, and examples from the first century AD still exist. Egg tempera was a primary method of painting until after 1500 when it was superseded by oil painting. A paint consisting of pigment and binder commonly used in the United States as poster paint is also often referred to as "tempera paint", although the binders in this paint are different from traditional tempera paint.
Violet is the color of light at the short wavelength end of the visible spectrum, between blue and invisible ultraviolet. It is one of the seven colors that Isaac Newton labeled when dividing the spectrum of visible light in 1672. Violet light has a wavelength between approximately 380 and 435 nanometers. The color's name is derived from the violet flower.
Ultramarine is a deep blue color pigment which was originally made by grinding lapis lazuli into a powder. Its lengthy grinding and washing process makes the natural pigment quite valuable—roughly ten times more expensive than the stone it comes from and as expensive as gold.
Agnolo Gaddi (c.1350–1396) was an Italian painter. He was born and died in Florence, and was the son of the painter Taddeo Gaddi, who was himself the major pupil of the Florentine master Giotto.
Ochre, or ocher in American English, is a natural clay earth pigment, a mixture of ferric oxide and varying amounts of clay and sand. It ranges in colour from yellow to deep orange or brown. It is also the name of the colours produced by this pigment, especially a light brownish-yellow. A variant of ochre containing a large amount of hematite, or dehydrated iron oxide, has a reddish tint known as "red ochre".
Vermilion is a color family and pigment most often used between antiquity and the 19th century from the powdered mineral cinnabar. It is synonymous with red orange, which often takes a modern form, but is 11% brighter.
Umber is a natural earth pigment consisting of iron oxide and manganese oxide; it has a brownish color that can vary between shades of yellow, red, and green. Umber is considered one of the oldest pigments known to humans, first seen in Ajanta Caves in 200 BC-600 AD. Umber's advantages are its highly versatile color, warm tone, and quick drying abilities. 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." The belief that its name derives from the word for shadow is fitting, as the color helps create shadows. The color is primarily imported from Cyprus. Umber is typically mined from open pits or underground mines and ground into a fine powder that is washed to remove impurities. In the 20th century, the rise of synthetic dyes decreased the demand for natural pigments such as umber.
Silverpoint is a traditional drawing technique first used by medieval scribes on manuscripts.
Viridian is a blue-green pigment, a hydrated chromium(III) oxide, of medium saturation and relatively dark in value. It is composed of a majority of green, followed by blue. The first recorded use of viridian as a color name in English was in the 1860s. Viridian takes its name from the Latin viridis, meaning "green". The pigment was first prepared in mid-19th-century Paris and remains available from several US manufacturers as prepared artists' colors in all media.
Cennino d'Andrea Cennini was an Italian painter influenced by Giotto. He was a student of Agnolo Gaddi in Florence. Gaddi trained under his father, called Taddeo Gaddi, who trained with Giotto.
Chrome yellow is a bright, warm yellow pigment that has been used in art, fashion, and industry for over two centuries. The pigment is derived from lead chromate, a chemical compound that was first synthesized in the early 1800s. The name "chrome yellow" comes from the French chemist Louis Nicolas Vauquelin, who discovered the element chromium in 1797.
Sinopia is a dark reddish-brown natural earth pigment, whose reddish colour comes from hematite, a dehydrated form of iron oxide. It was widely used in Classical Antiquity and the Middle Ages for painting, and during the Renaissance it was often used on the rough initial layer of plaster for the underdrawing for a fresco. The word came to be used both for the pigment and for the preparatory drawing itself, which may be revealed when a fresco is stripped from its wall for transfer.
Francesco II da Carrara, known as Francesco il Novello, was Lord of Padua after his father, Francesco I il Vecchio, renounced the lordship on 29 June 1388; he was a member of the family of Carraresi. He married Taddea, daughter of Niccolò II d'Este, Lord of Modena.
Working in layers is a system for creating artistic paintings that involve the use of more than one layer of paint.
Daniel Varney Thompson (1902–1980) was an American art historian and translator.
Varieties of the color red may differ in hue, chroma or lightness, or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a red or other hue mixed with white, a shade being mixed with black. A large selection of these various colors are shown below.
Stil de grain yellow or sap green is a pigment derived from berries of the buckthorn species Rhamnus saxatilis, which are commonly called Avignon berries or Persian berries after two historical areas of supply; latterly Italy was a major source. The color, whose principal chemical component is rhamnetin, was formerly called pink ; latterly, to distinguish it from light red "pink", the yellow "pink" was qualified as Dutch pink, brown pink, English pink, Italian pink, or French pink — the first three also applied to similar quercitron dyes from the American eastern black oak, Quercus velutina. Other names are Persian berries lake, yellow berries and buckthorn berries.
De pictura is a treatise or commentarii written by the Italian humanist and artist Leon Battista Alberti. The first version, composed in Latin in 1435, was not published until 1450. It is one of his three treatises on art; the other two are De statua and De re aedificatoria, that would form the Renaissance concept for the fine arts: painting, sculpture, and architecture.
Iron oxide red is a generic name of a ferric oxide pigment of the red color. Multiple shades based on both anhydrous Fe
2O
3 and its hydrates were known to painters since prehistory. The pigments were originally sourced from natural sources, since the 20th century they are mostly synthetic. These substances form one of the most commercially important groups of pigments. The names of the variants and sometimes reflect the location of a natural source, later transferred to the synthetic analog. Well-known examples include the Persian Gulf Oxide with 75% Fe
2O
3 and 25% silica, Spanish red with 85% of oxide, Tuscan red.
