Cobalt Blue
Cobalt blue is a blue pigment made by sintering cobalt(II) oxide with aluminium(III) oxide (alumina) at 1200 °C. Chemically, cobalt blue pigment is cobalt(II) oxide-aluminium oxide, or cobalt(II) aluminate, CoAl2O4. Cobalt blue is lighter and less intense than the (iron-cyanide based) pigment Prussian blue. It is extremely stable, and has historically been used as a coloring agent in ceramics (especially Chinese porcelain), jewelry, and paint. Transparent glasses are tinted with the silica-based cobalt pigment "smalt". Historical uses and production Ores containing cobalt have been used since antiquity as pigments to give a blue color to porcelain and glass. Cobalt blue in impure forms had long been used in Chinese porcelain. In 1742, Swedish chemist Georg Brandt showed that the blue color was due to a previously unidentified metal, cobalt. The first recorded use of ''cobalt blue'' as a color name in English was in 1777. It was independently discovered as an alumina ...

Blue
Blue is one of the three primary colours in the RYB color model, RYB colour model (traditional colour theory), as well as in the RGB color model, RGB (additive) colour model. It lies between Violet (color), violet and cyan on the optical spectrum, spectrum of visible light. The term ''blue'' generally describes colours perceived by humans observing light with a dominant wavelength that's between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colours; Azure (color), 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#Cause of the blue colour of the sky, Rayleigh scattering. An optical effect called the Tyndall effect explains Eye color#Blue, 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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optical Filter
An optical filter is a device that selectively transmits light of different wavelengths, usually implemented as a glass plane or plastic device in the optical path, which are either dyed in the bulk or have interference coatings. The optical properties of filters are completely described by their frequency response, which specifies how the magnitude and phase of each frequency component of an incoming signal is modified by the filter. Filters mostly belong to one of two categories. The simplest, physically, is the absorptive filter; then there are interference or dichroic filters. Many optical filters are used for optical imaging and are manufactured to be transparent; some used for light sources can be translucent. Optical filters selectively transmit light in a particular range of wavelengths, that is, colours, while absorbing the remainder. They can usually pass long wavelengths only (longpass), short wavelengths only (shortpass), or a band of wavelengths, bloc ...

Bugatti
Automobiles Ettore Bugatti was a German then French automotive industry, manufacturer of high performance vehicle, high-performance automobiles. The company was founded in 1909 in the then-German Empire, German city of Molsheim, Alsace, by the Italian-born industrial designer Ettore Bugatti. The cars were known for their design beauty and numerous race victories. Famous Bugatti automobiles include the Bugatti Type 35, Type 35 Grand Prix cars, the Bugatti Royale, Type 41 "Royale", the Bugatti Type 57, Type 57 "Atlantic" and the Bugatti Type 55, Type 55 sports car. The death of Ettore Bugatti in 1947 proved to be a severe blow to the marque, and the death of his son Jean Bugatti, Jean in 1939 meant that there was no successor to lead the factory. With no more than about 8,000 cars made, the company struggled financially, and it released one last model in the 1950s before eventually being purchased for its airplane parts business in 1963. In 1987, an Italian entrepreneur bought th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jeep
Jeep is an American automobile brand, now owned by multi-national corporation Stellantis. Jeep has been part of Chrysler since 1987, when Chrysler acquired the Jeep brand, along with other assets, from its previous owner, American Motors Corporation (AMC). Jeep's current product range consists solely of sport utility vehicles—both crossovers and fully off-road worthy SUVs and models, including one pickup truck. Previously, Jeep's range included other pick-ups, as well as small vans, and a few roadsters. Some of Jeep's vehicles—such as the Grand Cherokee—reach into the luxury SUV segment, a market segment the 1963 Wagoneer is considered to have started. Jeep sold 1.4 million SUVs globally in 2016, up from 500,000 in 2008, two-thirds of which in North America, and was Fiat-Chrysler's best selling brand in the U.S. during the first half of 2017. In the U.S. alone, over 2400 dealerships hold franchise rights to sell Jeep-branded vehicles, and if Jeep were spun off i ...

Automobiles
A car, or an automobile, is a motor vehicle with wheels. Most definitions of cars state that they run primarily on roads, Car seat, seat one to eight people, have four wheels, and mainly transport private transport#Personal transport, people rather than cargo. There are around one billion cars in use worldwide. The French inventor Nicolas-Joseph Cugnot built the first steam-powered road vehicle in 1769, while the Swiss inventor François Isaac de Rivaz designed and constructed the first internal combustion-powered automobile in 1808. The modern car—a practical, marketable automobile for everyday use—was invented in 1886, when the German inventor Carl Benz patented his Benz Patent-Motorwagen. Commercial cars became widely available during the 20th century. The 1901 Oldsmobile Curved Dash and the 1908 Ford Model T, both American cars, are widely considered the first mass-produced and mass-affordable cars, respectively. Cars were rapidly adopted in the US, where they replac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Post-Impressionists
Post-Impressionism (also spelled Postimpressionism) was a predominantly French art movement that developed roughly between 1886 and 1905, from the last Impressionist exhibition to the birth of Fauvism. Post-Impressionism emerged as a reaction against Impressionists' concern for the naturalistic depiction of light and colour. Its broad emphasis on abstract qualities or symbolic content means Post-Impressionism encompasses Les Nabis, Neo-Impressionism, Symbolism, Cloisonnism, the Pont-Aven School, and Synthetism, along with some later Impressionists' work. The movement's principal artists were Paul Cézanne (known as the father of Post-Impressionism), Paul Gauguin, Vincent van Gogh and Georges Seurat. The term Post-Impressionism was first used by art critic Roger Fry in 1906.Peter Morrin, Judith Zilczer, William C. Agee, ''The Advent of Modernism. Post-Impressionism and North American Art, 1900-1918'', High Museum of Art, 1986 Critic Frank Rutter in a review of the Salon d'Automne ...

Claude Monet
Oscar-Claude Monet (, ; ; 14 November 1840 – 5 December 1926) was a French painter and founder of Impressionism painting who is seen as a key precursor to modernism, especially in his attempts to paint nature as he perceived it. During his long career, he was the most consistent and prolific practitioner of Impressionism's philosophy of expressing one's perceptions of nature, especially as applied to ''En plein air, ''plein air'''' (outdoor) landscape painting. The term "Impressionism" is derived from the title of his painting ''Impression, Sunrise, Impression, soleil levant'', which was exhibited in 1874 at the First Impressionist Exhibition, initiated by Monet and a number of like-minded artists as an alternative to the Salon (Paris), Salon. Monet was raised in Le Havre, Normandy, and became interested in the outdoors and drawing from an early age. Although his mother, Louise-Justine Aubrée Monet, supported his ambitions to be a painter, his father, Claude-Adolphe, disa ...

Pierre-Auguste Renoir
Pierre-Auguste Renoir (; ; 25 February 1841 – 3 December 1919) was a French people, French artist who was a leading painter in the development of the Impressionism, Impressionist style. As a celebrator of beauty and especially femininity, feminine sensuality, it has been said that "Renoir is the final representative of a tradition which runs directly from Peter Paul Rubens, Rubens to Antoine Watteau, Watteau." He was the father of actor Pierre Renoir (1885–1952), filmmaker Jean Renoir (1894–1979) and ceramic artist Claude Renoir (1901–1969).

Impressionists
Impressionism was a 19th-century art movement characterized by visible brush strokes, open composition, emphasis on accurate depiction of light in its changing qualities (often accentuating the effects of the passage of time), ordinary subject matter, unusual visual angles, and inclusion of movement as a crucial element of human perception and experience. Impressionism originated with a group of Paris-based artists whose independent exhibitions brought them to prominence during the 1870s and 1880s. The Impressionists faced harsh opposition from the conventional art community in France. The name of the style derives from the title of a Claude Monet work, ''Impression, soleil levant'' ('' Impression, Sunrise''), which provoked the critic Louis Leroy to coin the term in a satirical 1874 review of the First Impressionist Exhibition published in the Parisian newspaper '' Le Charivari''. The development of Impressionism in the visual arts was soon followed by analogous styles in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
