Brown is a color. It can be considered a composite color, but it is mainly a darker shade of orange. In the CMYK color model used in printing or painting, brown is usually made by combining the colors orange and black. In the RGB color model used to project colors onto television screens and computer monitors, brown combines red and green. The color brown is seen widely in nature, wood, soil, human hair color, eye color and skin pigmentation. Brown is the color of dark wood or rich soil. According to public opinion surveys in Europe and the United States, brown is the least favorite color of the public; it is often associated with plainness, the rustic, feces, and poverty. More positive associations include baking, warmth, wildlife, and the autumn. Etymology The term is from Old English , in origin for any dusky or dark shade of color. The first recorded use of ''brown'' as a color name in English was in 1000. The Common Germanic adjectives ''*brûnoz and *brûnâ'' me ...

Color
Color (American English) or colour (British English) is the visual perceptual property deriving from the spectrum of light interacting with the photoreceptor cells of the eyes. Color categories and physical specifications of color are associated with objects or materials based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space, colors can be identified numerically by their coordinates. Because perception of color stems from the varying spectral sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. These physical or physiological quantifications of color, however, do not fully explain the psychophysical perception of color appearance. Color science includes the perception of color by the eye and brain, the origin of color in materials, color theory in art, and the physics of electr ...

Lascaux Cave
Lascaux ( , ; french: Grotte de Lascaux , "Lascaux Cave") is a network of caves near the village of Montignac, Dordogne, Montignac, in the Departments of France, department of Dordogne in southwestern France. Over 600 Parietal art, parietal cave painting, wall paintings cover the interior walls and ceilings of the cave. The paintings represent primarily large animals, typical local contemporary fauna that correspond with the fossil record of the Upper Paleolithic in the area. They are the combined effort of many generations and, with continued debate, the age of the paintings is now usually estimated at around 17,000 years (early Magdalenian). Because of the outstanding prehistoric art in the cave, Lascaux was inducted into the UNESCO World Heritage List in 1979, as an element of the ''Prehistoric Sites and Decorated Caves of the Vézère Valley''. The original caves have been closed to the public since 1963, as their condition was deteriorating, but there are now a number of r ...

Rose Madder
Rose madder (also known as madder) is a red paint made from the pigment madder lake, a traditional lake pigment extracted from the common madder plant '' Rubia tinctorum''. Madder lake contains two organic red dyes: alizarin and purpurin. As a paint, it has been described as a fugitive, transparent, nonstaining, mid valued, moderately dull violet red pigment in tints and medium solutions, darkening to an impermanent, dull magenta red in masstone. History Madder has been cultivated as a dyestuff since antiquity in Central Asia, South Asia, and Egypt, where it was grown as early as 1500 BC. Cloth dyed with madder root dye was found in the tomb of the Pharaoh Tutankhamun and on an Egyptian tomb painting from the Graeco-Roman period, diluted with gypsum to produce a pink color. It was also found in ancient Greece (in Corinth), and in Italy in the Baths of Titus and the ruins of Pompeii. It is referred to in the Talmud as well as mentioned in writings by Dioscorides (who ...

Woad
''Isatis tinctoria'', also called woad (), dyer's woad, or glastum, is a flowering plant in the family Brassicaceae (the mustard family) with a documented history of use as a blue dye and medicinal plant. Its genus name, Isatis, derives from the ancient Greek word for the plant, ἰσάτις. It is occasionally known as Asp of Jerusalem. Woad is also the name of a blue dye produced from the leaves of the plant. Woad is native to the steppe and desert zones of the Caucasus, Central Asia to Eastern Siberia and Western Asia but is now also found in South-Eastern and Central Europe and western North America. Since ancient times, woad was an important source of blue dye and was cultivated throughout Europe, especially in Western and Southern Europe. In medieval times, there were important woad-growing regions in England, Germany and France. Towns such as Toulouse became prosperous from the woad trade. Woad was eventually replaced by the more colourfast ''Indigofera tinctoria'' a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russet (cloth)
Russet is a coarse cloth made of wool and dyed with woad and madder to give it a subdued grey or brown shade. By the statute of 1363, poor English people were required to wear russet or cheap blanket. Humble squires and priests, such as Franciscans wore russet as a sign of humility but preferred a good quality russet such as that made in Colchester, which was better than the cheapest cloth. The medieval poem '' Piers Plowman'' describes the virtuous Christian: The ballad ''Of Patient Grissel and a Noble Marquess'' which was retold as ''Pamela'', has the heroine's aristocratic clothes of silk and velvet contrasted with her "country russet" which again signifies rustic virtue. Oliver Cromwell wrote "I had rather have a plain russet-coated Captain ...than that which you call a Gentleman and is nothing else." See also * Shoddy * Sukmana A sukmana is a type of traditional coat once worn by peasants in Poland, and some other Central European countries, as well as Hungary (where ...

Amphora
An amphora (; grc, ἀμφορεύς, ''amphoreús''; English plural: amphorae or amphoras) is a type of container with a pointed bottom and characteristic shape and size which fit tightly (and therefore safely) against each other in storage rooms and packages, tied together with rope and delivered by land or sea. The size and shape have been determined from at least as early as the Neolithic Period. Amphorae were used in vast numbers for the transport and storage of various products, both liquid and dry, but mostly for wine. They are most often ceramic, but examples in metals and other materials have been found. Versions of the amphorae were one of many shapes used in Ancient Greek vase painting. The amphora complements a vase, the pithos, which makes available capacities between one-half and two and one-half tons. In contrast, the amphora holds under a half-ton, typically less than . The bodies of the two types have similar shapes. Where the pithos may have multiple smal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terracotta
Terracotta, terra cotta, or terra-cotta (; ; ), in its material sense as an earthenware substrate, is a clay-based ceramic glaze, unglazed or glazed ceramic where the pottery firing, fired body is porous. In applied art, craft, construction, and architecture, terracotta is the term normally used for sculpture made in earthenware and also for various practical uses, including bowl (vessel), vessels (notably flower pots), water and waste water pipes, tile, roofing tiles, bricks, and surface embellishment in building construction. The term is also used to refer to the natural Terra cotta (color), brownish orange color of most terracotta. In archaeology and art history, "terracotta" is often used to describe objects such as figurines not made on a potter's wheel. Vessels and other objects that are or might be made on a wheel from the same material are called earthenware pottery; the choice of term depends on the type of object rather than the material or firing technique. Unglazed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dun Gene
The dun gene is a dilution gene that affects both red and black pigments in the coat color of a horse. The dun gene lightens most of the body while leaving the mane, tail, legs, and primitive markings the shade of the undiluted base coat color. A dun horse always has a dark dorsal stripe down the middle of its back, usually has a darker face and legs, and may have transverse striping across the shoulders or horizontal striping on the back of the forelegs. Body color depends on the underlying coat color genetics. A classic "bay dun" is a gray-gold or tan, characterized by a body color ranging from sandy yellow to reddish brown. Duns with a chestnut base may appear a light tan shade, and those with black base coloration are a smoky gray. Manes, tails, primitive markings, and other dark areas are usually the shade of the undiluted base coat color. The dun gene may interact with all other coat color alleles. Taxonomic distribution Dun is believed to be the ancestral or wild type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raphael
Raffaello Sanzio da Urbino, better known as Raphael (; or ; March 28 or April 6, 1483April 6, 1520), was an Italian painter and architect of the High Renaissance. List of works by Raphael, His work is admired for its clarity of form, ease of composition, and visual achievement of the Renaissance Neoplatonism, Neoplatonic ideal of human grandeur. Together with Leonardo da Vinci and Michelangelo, he forms the traditional trinity of great masters of that period. His father was court painter to the ruler of the small but highly cultured city of Urbino. He died when Raphael was eleven, and Raphael seems to have played a role in managing the family workshop from this point. He trained in the workshop of Perugino, and was described as a fully trained "master" by 1500. He worked in or for several cities in north Italy until in 1508 he moved to Rome at the invitation of the pope, to work on the Vatican Palace. He was given a series of important commissions there and elsewhere in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
