Cerulean
Cerulean (), also spelled caerulean, is a shade of blue ranging between azure and a darker sky blue. The first recorded use of ''cerulean'' as a colour name in English was in 1590. The word is derived from the Latin word '' caeruleus'', "dark blue, blue, or blue-green", which in turn probably derives from ''caerulum'', diminutive of ''caelum'', "heaven, sky". "Cerulean blue" is the name of a pigment. The pigment was discovered in the late eighteenth century and designated as cerulean blue in the nineteenth century. Cerulean blue pigment The primary chemical constituent of the pigment is cobalt(II) stannate (). The precise hue of the pigment is dependent on a variable silicate component. The pigment Cerulean blue was discovered in 1789 by the Swiss chemist Albrecht Höpfner. Subsequently, there was a limited German production under the name of ''Cölinblau''. It was in 1860 first marketed in the United Kingdom by colourman George Rowney, as "coeruleum". Other nineteenth c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerulean Warbler
The cerulean warbler (''Setophaga cerulea'') is a small songbird in the family Parulidae. It is a long-distance migrant, breeding in eastern North American hardwood forests. In the non-breeding season, it winters on the eastern slope of the Andes in South America, preferring subtropical forests. It displays strong sexual dichromatism: Adult males have cerulean blue and white , with a black necklace across the breast and black streaks on the back and flanks. Females and immature birds have bluish-green upperparts, a pale stripe over the eye, no streaking, and are yellow below. All have two white wing bars and a thin, pointed . The cerulean warbler is insectivorous and predominantly feeds on insect larvae, though it also takes winged insects. It forages for prey and nests high in forest canopies. Individuals are strongly territorial; males will defend areas of forests. Males arrive on breeding grounds about one to two weeks earlier than females. Breeding and incubation take pl ...

The Devil Wears Prada (film)
''The Devil Wears Prada'' is a 2006 American comedy-drama film directed by David Frankel and produced by Wendy Finerman. The screenplay, written by Aline Brosh McKenna, is based on Lauren Weisberger's 2003 novel of the same name. The film adaptation stars Meryl Streep as Miranda Priestly, a powerful fashion magazine editor, and Anne Hathaway as Andrea "Andy" Sachs, a college graduate who goes to New York City and lands a job as Priestly's co-assistant.

Cerulean Flycatcher
The cerulean flycatcher (''Eutrichomyias rowleyi'') is a medium-sized (up to 18 cm long), blue passerine with bright cerulean blue plumage, a bare white orbital ring, dark brown iris, bluish black bill and pale blue-grey below. The young has a shorter tail and grey underparts. It is the only member of the monotypic genus ''Eutrichomyias''. Although it resembles a monarch flycatcher, it is actually related to the fantails. Taxonomy and systematics The scientific name commemorates the British explorer and ornithologist George Dawson Rowley. The cerulean flycatcher was originally described in the genus '' Zeocephus'', and until recently was known as the cerulean paradise-flycatcher. Alternate names include Rowley's flycatcher and Rowley's paradise-flycatcher. Although initially classified in Monarchidae, a 2017 study involving sequencing of DNA from the type specimen found that it was a member of the fantail family Rhipiduridae, being classified in the basal subfamily Lamprol ...

Cerulean Cuckooshrike
The cerulean cuckooshrike (''Coracina temminckii'') is a species of bird in the family Campephagidae. It is endemic to the island of Sulawesi in Indonesia. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. Other common names for this bird include the Sulawesi cuckooshrike, the Celebes cuckooshrike and Temminck's cuckooshrike. Taxonomy The cerulean cuckooshrike was first described by the German naturalist Salomon Müller in 1843. The specific name honours the Dutch zoologist and ornithologist Coenraad Jacob Temminck, the director of the National Natural History Museum at Leiden who had sent Müller to the East Indies to collect specimens. Three subspecies are recognised; ''C. t. temminckii'' from the northern peninsula of Sulawesi, ''C. t. rileyi'' from central and southeastern Sulawesi and ''C. t. tonkeana'' from eastern Sulawesi.

Cerulean Kingfisher
The cerulean kingfisher (''Alcedo coerulescens'') is a kingfisher in the subfamily Alcedininae which is native to parts of Indonesia. With an overall metallic blue impression, it is very similar to the common kingfisher, but it is white underneath instead of orange. Males average bluer than females, which have a greenish cast. This species is sometimes called the small blue kingfisher but in Indonesia and parts of Asia that name refers to ''Alcedo atthis'' (common kingfisher). Taxonomy The first formal description of the cerulean kingfisher was by the French ornithologist Louis Jean Pierre Vieillot in 1818. He coined the binomial name ''Alcedo coerulescens''. The specific epithet ''coerulescens'' is from the Latin ''caerulescens'' meaning "bluish". The species is monotypic. Description The cerulean kingfisher is a small kingfisher with a length of . The upperparts are a range of shades of blue with white lores and a prominent white patch on each side of the neck. The underpa ...

Blue
Blue is one of the three primary colours in the RYB colour model (traditional colour theory), as well as in the RGB (additive) colour model. It lies between violet and cyan on the spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colours; azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called Tyndall effect explains blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective. Blue has been an important colour in art and decoration since ancient times. The semi-precious stone lapis lazuli was used in ancient Egypt for jewellery and ornament and later, in the Renaissance, to make the pigment ultramarine, the most expensive of all pigments.

Quaternary Color
A tertiary color or intermediate color is a color made by mixing full saturation of one primary color with half saturation of another primary color and none of a third primary color, in a given color space such as RGB color model, RGB, CMYK color model, CMYK (more modern) or RYB color model, RYB (traditional). Tertiary colors have general names, one set of names for the RGB color wheel and a different set for the RYB color wheel. These names are shown below. Another definition of tertiary color is provided by color theorists such as Moses Harris and Josef Albers, who suggest that tertiary colors are created by intermixing pairs of secondary colors: orange-green, green-purple, purple-orange; or by intermixing complementary colors. This approach to tertiary color relates specifically to color in the form of paints, pigments, and dyes. Comparison of RGB and RYB color wheels The RYB color wheel was invented centuries before the 1890s, when it was found by experiment that magenta, ye ...

Summer's Day
''Summer's Day'' (or ''Jour d'eté'') is an oil on canvas painting by the French Impressionist painter Berthe Morisot, created in 1879. The painting depicts two women seated in a row boat, and was painted in the Bois de Boulogne. It is held at the National Gallery, in London. History During the winter of 1878-1879, Morisot had her first child, Julie. The following summer, she walked every day with Julie and her nurse in the Bois de Boulogne. After a long period spent indoors, it gave her the wish to start painting outdoors again. However, she did not wanted to leave her child alone with her nanny for long periods of time. Finally, she found a balance between her maternal duty and her wish to resume her painting, by bringing her models to the park, so she could work there and be with Julie at the same time. Morisot exhibited ''Summer's Day'' during the Fifth Great Impressionist Exhibition, in 1880, along with several other works she produced during the summer of 1879. In fact, for ...

Pigment
A pigment is a colored material that is completely or nearly insoluble in water. In contrast, dyes are typically soluble, at least at some stage in their use. Generally dyes are often organic compounds whereas pigments are often inorganic compounds. Pigments of prehistoric and historic value include ochre, charcoal, and lapis lazuli. Economic impact In 2006, around 7.4 million tons of inorganic, organic, and special pigments were marketed worldwide. Estimated at around US$14.86 billion in 2018 and will rise at over 4.9% CAGR from 2019 to 2026. The global demand for pigments was roughly US$20.5 billion in 2009. According to an April 2018 report by ''Bloomberg Businessweek'', the estimated value of the pigment industry globally is $30 billion. The value of titanium dioxide – used to enhance the white brightness of many products – was placed at $13.2 billion per year, while the color Ferrari red is valued at $300 million each year.

Stannate
In chemistry the term stannate refers to compounds of tin (Sn). Stannic acid (Sn(OH)4), the formal precursor to stannates, does not exist and is actually a hydrate of SnO2. The term is also used in naming conventions as a suffix; for example the hexachlorostannate ion is . In materials science, two kinds of tin oxyanions are distinguished: *''orthostannates'' contain discrete units (e.g. K4SnO4) or have a spinel structure (e.g. Mg2SnO4) *''metastannates'' with a stoichiometry MIISnO3, MSnO3 which may contain polymeric anions or may be sometimes better described as mixed oxides These materials are semiconductors."Preparation, characterization and structure of metal stannates: a new family of photocatalysts for organic pollutants degradation."
