Cobalt Blue (horse)
Cobalt blue is a blue pigment made by sintering cobalt(II) oxide with aluminum(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 historically has 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 a pure alumina- ...

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. I ...

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, block ...

Bugatti
Automobiles Ettore Bugatti was a German then French manufacturer of high-performance automobiles. The company was founded in 1909 in the then- German city of Molsheim, Alsace, by the Italian-born industrial designer Ettore Bugatti. The cars were known for their design beauty and for their many race victories. Famous Bugatti automobiles include the Type 35 Grand Prix cars, the Type 41 "Royale", the Type 57 "Atlantic" and the Type 55 sports car. The death of Ettore Bugatti in 1947 proved to be a severe blow for the marque, and the death of his son Jean Bugatti in 1939 meant that there was no successor to lead the factory. No more than about 8,000 cars were 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 the brand name and revived it as Bugatti Automobili SpA. Under Ettore Bugatti Founder Ettore Bugatti was born in Mi ...

Jeep
Jeep is an American automobile marque, now owned by multi-national corporation Stellantis. Jeep has been part of Chrysler since 1987, when Chrysler acquired the Jeep brand, along with remaining 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 ...

Automobiles
A car or automobile is a motor vehicle with wheels. Most definitions of ''cars'' say that they run primarily on roads, seat one to eight people, have four wheels, and mainly transport people instead of goods. The year 1886 is regarded as the birth year of the car, when German inventor Carl Benz patented his Benz Patent-Motorwagen. Cars became widely available during the 20th century. One of the first cars affordable by the masses was the 1908 Model T, an American car manufactured by the Ford Motor Company. Cars were rapidly adopted in the US, where they replaced animal-drawn carriages and carts. In Europe and other parts of the world, demand for automobiles did not increase until after World War II. The car is considered an essential part of the developed economy. Cars have controls for driving, parking, passenger comfort, and a variety of lights. Over the decades, additional features and controls have been added to vehicles, making them progressively more com ...

Vincent Van Gogh
Vincent Willem van Gogh (; 30 March 185329 July 1890) was a Dutch Post-Impressionist painter who posthumously became one of the most famous and influential figures in Western art history. In a decade, he created about 2,100 artworks, including around 860 oil paintings, most of which date from the last two years of his life. They include landscapes, still lifes, portraits and self-portraits, and are characterised by bold colours and dramatic, impulsive and expressive brushwork that contributed to the foundations of modern art. Not commercially successful, he struggled with severe depression and poverty, eventually leading to his suicide at age thirty-seven. Born into an upper-middle class family, Van Gogh drew as a child and was serious, quiet, and thoughtful. As a young man, he worked as an art dealer, often traveling, but became depressed after he was transferred to London. He turned to religion and spent time as a Protestant missionary in southern Belgium. He drif ...

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 Sal ...

Claude Monet
Oscar-Claude Monet (, , ; 14 November 1840 – 5 December 1926) was a French painter and founder of impressionist 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 before nature, especially as applied to '' plein air'' (outdoor) landscape painting. The term "Impressionism" is derived from the title of his painting '' Impression, soleil levant'', exhibited in the 1874 ("exhibition of rejects") initiated by Monet and his associates as an alternative to the 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, disapproved and wanted him to pursue a career in business. He was very close to his m ...

Pierre-Auguste Renoir
Pierre-Auguste Renoir (; 25 February 1841 – 3 December 1919) was a French artist who was a leading painter in the development of the Impressionist style. As a celebrator of beauty and especially feminine sensuality, it has been said that "Renoir is the final representative of a tradition which runs directly from Rubens to Watteau." He was the father of actor Pierre Renoir (1885–1952), filmmaker Jean Renoir (1894–1979) and ceramic artist Claude Renoir (1901–1969). He was the grandfather of the filmmaker Claude Renoir (1913–1993), son of Pierre. Life Youth Pierre-Auguste Renoir was born in Limoges, Haute-Vienne, France, in 1841. His father, Léonard Renoir, was a tailor of modest means, so, in 1844, Renoir's family moved to Paris in search of more favorable prospects. The location of their home, in rue d’Argenteuil in central Paris, placed Renoir in proximity to the Louvre. Although the young Renoir had a natural proclivity for drawing, he exhibited a greate ...

Impressionists
Impressionism was a 19th-century art movement characterized by relatively small, thin, yet 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 review published in the Parisian newspaper '' Le Charivari''. The development of Impressionism in the visual arts was soon followed by analogous styles in other media tha ...
