Alizarin Crimson (color)
Alizarin crimson is a shade of red that is biased slightly more towards purple than towards orange on the color wheel and has a blue undertone. It is named after the organic dye alizarin, found in the madder plant, and the related synthetic lake pigment alizarin crimson (PR83 in the Color Index). William Henry Perkin had co-discovered a way to synthesize the pigment alizarin, which became known as the color alizarin crimson. Its consistency and lightfastness quickly made it a favourite red pigment for artists. Alizarin crimson can create a wide range of rich, permanent purples and browns. The dye was prominently used for dyeing clothes and traces were found in Ancient Egypt, Persia and the ruins of Pompeii. By the seventh century BC, the dye had been made into a lake pigment and was used across Europe, the Middle East and Asia. By this time the use of madder dye and pigment were widespread, but they remained costly and time-consuming to produce. Alizarin crimson was a popu ...

Pompeii
Pompeii (, ) was an ancient city located in what is now the ''comune'' of Pompei near Naples in the Campania region of Italy. Pompeii, along with Herculaneum and many villas in the surrounding area (e.g. at Boscoreale, Stabiae), was buried under of volcanic ash and pumice in the Eruption of Mount Vesuvius in 79 AD. Largely preserved under the ash, the excavated city offered a unique snapshot of Roman life, frozen at the moment it was buried, although much of the detailed evidence of the everyday life of its inhabitants was lost in the excavations. It was a wealthy town, with a population of ca. 11,000 in AD 79, enjoying many fine public buildings and luxurious private houses with lavish decorations, furnishings and works of art which were the main attractions for the early excavators. Organic remains, including wooden objects and human bodies, were interred in the ash. Over time, they decayed, leaving voids that archaeologists found could be used as moulds to make plaste ...

Crimson
Crimson is a rich, deep red color, inclining to purple. It originally meant the color of the kermes dye produced from a scale insect, ''Kermes vermilio'', but the name is now sometimes also used as a generic term for slightly bluish-red colors that are between red and rose. It is the national color of Nepal. History Crimson (NR4) is produced using the dried bodies of a scale insect, ''Kermes'', which were gathered commercially in Mediterranean countries, where they live on the kermes oak, and sold throughout Europe. Kermes dyes have been found in burial wrappings in Anglo-Scandinavian York. They fell out of use with the introduction of cochineal, also made from scale insects, because although the dyes were comparable in quality and color intensity, it needed ten to twelve times as much kermes to produce the same effect as cochineal. Carmine is the name given to the dye made from the dried bodies of the female cochineal, although the name crimson is sometimes applied to ...

Alizarin
Alizarin (also known as 1,2-dihydroxyanthraquinone, Mordant Red 11, C.I. 58000, and Turkey Red) is an organic compound with formula that has been used throughout history as a prominent red dye, principally for dyeing textile fabrics. Historically it was derived from the roots of plants of the madder genus.The primary madder species from which alizarin historically has been obtained is ''Rubia tinctorum''. See also In 1869, it became the first natural dye to be produced synthetically. Alizarin is the main ingredient for the manufacture of the madder lake pigments known to painters as rose madder and alizarin crimson. Alizarin in the most common usage of the term has a deep red color, but the term is also part of the name for several related non-red dyes, such as Alizarine Cyanine Green and Alizarine Brilliant Blue. A notable use of alizarin in modern times is as a staining agent in biological research because it stains free calcium and certain calcium compounds a red or ligh ...

Madder
''Rubia'' is the type genus of the Rubiaceae family of flowering plants, which also contains coffee. It contains around 80 species of perennial scrambling or climbing herbs and subshrubs native to the Old World. The genus and its best-known species are commonly known as madder, e.g. ''Rubia tinctorum'' (common madder), ''Rubia peregrina'' (wild madder), and ''Rubia cordifolia'' (Indian madder). Uses ''Rubia'' was an economically important source of a red pigment in many regions of Asia, Europe and Africa. The genus name ''Rubia'' derives from the Latin ' meaning "red". The plant's roots contain an anthracene compound called alizarin that gives its red colour to a textile dye known as Rose madder. It was also used as a colourant, especially for paint, that is referred to as Madder lake. The synthesis of alizarin greatly reduced demand for the natural compound. In Georgia, Rubia is used for dying Easter eggs in red. History Several species, such as ''Rubia tinctorum'' in Euro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Joy Of Painting

Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...

Middle East
The Middle East ( ar, الشرق الأوسط, ISO 233: ) is a geopolitical region commonly encompassing Arabian Peninsula, Arabia (including the Arabian Peninsula and Bahrain), Anatolia, Asia Minor (Asian part of Turkey except Hatay Province), East Thrace (European part of Turkey), Egypt, Iran, the Levant (including Syria (region), Ash-Shām and Cyprus), Mesopotamia (modern-day Iraq), and the Socotra Governorate, Socotra Archipelago (a part of Yemen). The term came into widespread usage as a replacement of the term Near East (as opposed to the Far East) beginning in the early 20th century. The term "Middle East" has led to some confusion over its changing definitions, and has been viewed by some to be discriminatory or too Eurocentrism, Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of Western Asia (including Iran), but without the South Caucasus, and additionally includes all of Egypt (not just the Sina ...
