Crimson Moonlight Albums
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 thes ...

Web Colors
Web colors are colors used in displaying web pages on the World Wide Web, and the methods for describing and specifying those colors. Colors may be specified as an RGB triplet or in hexadecimal format (a ''hex triplet'') or according to their common English names in some cases. A color tool or other graphics software is often used to generate color values. In some uses, hexadecimal color codes are specified with notation using a leading number sign (#). A color is specified according to the intensity of its red, green and blue components, each represented by eight bits. Thus, there are 24 bits used to specify a web color within the sRGB gamut, and 16,777,216 colors that may be so specified. Colors outside the sRGB gamut can be specified in Cascading Style Sheets by making one or more of the red, green and blue components negative or greater than 100%, so the color space is theoretically an unbounded extrapolation of sRGB similar to scRGB. Specifying a non-sRGB color this way req ...

Pietro Andrea Mattioli
Pietro Andrea Gregorio Mattioli (; 12 March 1501 – ) was a doctor and naturalist born in Siena. Biography He received his MD at the University of Padua in 1523, and subsequently practiced the profession in Siena, Rome, Trento and Gorizia, becoming personal physician of Ferdinand II, Archduke of Further Austria in Prague and Ambras Castle, and of Maximilian II, Holy Roman Emperor in Vienna. Mattioli described the first case of cat allergy. His patient was so sensitive to cats that if he was sent into a room with a cat he reacted with agitation, sweating and pallor. A careful student of botany, he described 100 new plants and coordinated the medical botany of his time in his ''Discorsi'' ("Commentaries") on the ''De Materia Medica'' of Dioscorides. The first edition of Mattioli's work, the Italian translation of ''De Materia Medica'', supplemented with his own commentaries, appeared in 1544 in Venice. There were several later editions in Italian. In 1554 the first edition ...

Turkic Languages
The Turkic languages are a language family of over 35 documented languages, spoken by the Turkic peoples of Eurasia from Eastern Europe and Southern Europe to Central Asia, East Asia, North Asia (Siberia), and Western Asia. The Turkic languages originated in a region of East Asia spanning from Mongolia to Northwest China, where Proto-Turkic is thought to have been spoken, from where they expanded to Central Asia and farther west during the first millennium. They are characterized as a dialect continuum. Turkic languages are spoken by some 200 million people. The Turkic language with the greatest number of speakers is Turkish language, Turkish, spoken mainly in Anatolia and the Balkans; its native speakers account for about 38% of all Turkic speakers. Characteristic features such as vowel harmony, agglutination, subject-object-verb order, and lack of grammatical gender, are almost universal within the Turkic family. There is a high degree of mutual intelligibility, upon mode ...

Kermes (genus)
''Kermes'' is a genus of scale insects in the order Hemiptera. They feed on the sap of evergreen oaks; the females produce a red dye, also called " kermes", that is the source of natural crimson. The word "kermes" is derived from Persian or Turkish ''qirmiz'' or ''kirmizi'' ( قرمز), "crimson" (both the colour and the dyestuff). There are some 20 species, including: * '' Kermes bacciformis'' Leonardi, 1908 * '' Kermes corticalis'' (Nassonov, 1908) * ''Kermes echinatus'' (Balachowsky, 1953) * '' Kermes gibbosus'' Signoret, 1875 * '' Kermes ilicis'' (Linnaeus, 1758) * '' Kermes roboris'' (Fourcroy, 1785) * ''Kermes vermilio ''Kermes vermilio'' is a species of '' Kermes'' so which feeds on trees. Some of the species are used by humans to make vermilion; though an at-similar-time-of-discovery mineral form in many cultures is cinnabar (HgS, Mercury Sulphide, crystalli ...''

Medieval Latin
Medieval Latin was the form of Literary Latin used in Roman Catholic Western Europe during the Middle Ages. In this region it served as the primary written language, though local languages were also written to varying degrees. Latin functioned as the main medium of scholarly exchange, as the liturgical language of the Church, and as the working language of science, literature, law, and administration. Medieval Latin represented a continuation of Classical Latin and Late Latin, with enhancements for new concepts as well as for the increasing integration of Christianity. Despite some meaningful differences from Classical Latin, Medieval writers did not regard it as a fundamentally different language. There is no real consensus on the exact boundary where Late Latin ends and Medieval Latin begins. Some scholarly surveys begin with the rise of early Ecclesiastical Latin in the middle of the 4th century, others around 500, and still others with the replacement of written Late Latin ...

Old Spanish
Old Spanish, also known as Old Castilian ( es, castellano antiguo; osp, romance castellano ), or Medieval Spanish ( es, español medieval), was originally a dialect of Vulgar Latin spoken in the former provinces of the Roman Empire that provided the root for the early form of the Spanish language that was spoken on the Iberian Peninsula from the 10th century until roughly the beginning of the 15th century, before a ''consonantal readjustment'' gave rise to the evolution of modern Spanish. The poem ('The Poem of the Cid'), published around 1200, is the best known and most extensive work of literature in Old Spanish. Phonology The phonological system of Old Spanish was quite similar to that of other medieval Romance languages. Sibilants Among the consonants, there were seven sibilants, including three sets of voiceless/voiced pairs: *Voiceless alveolar affricate : represented by before , , , and by before or *Voiced alveolar affricate : represented by *Voiceless apicoa ...

Umber
Umber is a natural brown earth pigment that contains iron oxide and manganese oxide. In its natural form, it is called raw umber. When Calcination, calcined, the color becomes warmer and it becomes known as burnt umber. Its name derives from ''terra d'ombra'', or earth of Umbria, the Italian name of the pigment. Umbria is a mountainous region in central Italy where the pigment was originally extracted. The word also may be related to the Latin word ''umbra'', meaning "shadow". 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 color of the natural earth depends primarily upon the proportions of iron oxide and manganese in the clay. 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. Commercial umber pigments vary in color depending on their origin and how they are proces ...

Sienna
Sienna (from it, terra di Siena, meaning "Siena earth") is an earth pigment containing iron oxide and manganese oxide. In its natural state, it is yellowish brown and is called raw sienna. When heated, it becomes a reddish brown and is called burnt sienna.''Shorter Oxford English Dictionary'', 5th Edition (2002) It takes its name from the city-state of Siena, where it was produced 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. The first recorded use of ''sienna'' as a color name in English was in 1760. The normalized color coordinates for sienna are identical to kobe, first recorded as a color name in English in 1924. Earth colors Like the other earth colors, such as yellow ochre and umber, sienna is a clay containing iron oxide, called limonite, which in its natural state has a yellow ...

Ochre
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" (or, in some dialects, ruddle). The word ochre also describes clays coloured with iron oxide derived during the extraction of tin and copper. Earth pigments Ochre is a family of earth pigments, which includes yellow ochre, red ochre, purple ochre, sienna, and umber. The major ingredient of all the ochres is iron(III) oxide-hydroxide, known as limonite, which gives them a yellow colour. * Yellow ochre, , is a hydrated iron hydroxide (limonite) also called gold ochre. * Red ochre, , takes its reddish colour from the mineral hematite, which is an anhydrous iron ...

Alum
An alum () is a type of chemical compound, usually a hydrated double salt, double sulfate salt (chemistry), salt of aluminium with the general chemical formula, formula , where is a valence (chemistry), monovalent cation such as potassium or ammonium. By itself, "alum" often refers to potassium alum, with the formula . Other alums are named after the monovalent ion, such as sodium alum and ammonium alum. The name "alum" is also used, more generally, for salts with the same formula and structure, except that aluminium is replaced by another valence (chemistry), trivalent metal ion like chromium#Chromium(III), chromium, and/or sulfur is replaced by another chalcogen like selenium. The most common of these analogs is chrome alum . In most industries, the name "alum" (or "papermaker's alum") is used to refer to aluminium sulfate, , which is used for most industrial flocculation (the variable is an integer whose size depends on the amount of water absorbed into the alum). In medic ...

Madder Lake
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 ...

Carl Liebermann
Carl Theodore Liebermann (23 February 1842 – 28 December 1914) was a German chemist and student of Adolf von Baeyer. Life Liebermann first studied at the University of Heidelberg where Robert Wilhelm Bunsen was teaching. He then joined the group of Adolf von Baeyer at the University of Berlin where he received his PhD in 1865. Together with Carl Gräbe, Liebermann synthesised the orange-red dye alizarin in 1868. After his habilitation in 1870 he became professor at the University of Berlin after Adolf von Baeyer left for the University of Strasbourg. Shortly after Liebermann retired, in 1914, he died. Work In 1826, the French chemist Pierre Jean Robiquet had isolated from the root of a plant, madder, and defined the structure of, alizarin, a remarkable red dye. Liebermann's 1868 discovery that alizarin can be reduced to form anthracene, which is an abundant component in coal tar, opened the road for synthetic alizarin. The patent of Liebermann and Carl Gräbe for the s ...
