Amber (colour)
The color amber is a pure chroma color, located on the color wheel midway between the colors of yellow and orange. The color name is derived from the material also known as amber, which is commonly found in a range of yellow-orange-brown-red colors; likewise, as a color ''amber'' can refer to a range of yellow-orange colors. In English, the first recorded use of the term as a color name, rather than a reference to the specific substance, was in 1500. SAE/ECE amber Amber is one of several technically defined colors used in automotive signal lamps. In North America, SAE standard J578 governs the colorimetry of vehicle lights, while outside North America the internationalized European ECE regulations hold force. Both standards designate a range of orange-yellow hues in the CIE color space as "amber". In the past, the ECE amber definition was more restrictive than the SAE definition, but the current ECE definition is identical to the more permissive SAE standard. The SAE form ...

Tertiary 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, CMYK (more modern) or 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, yellow, and cyan are the primary colors of pigment, n ...

SRGB
sRGB is a standard RGB (red, green, blue) color space that HP and Microsoft created cooperatively in 1996 to use on monitors, printers, and the World Wide Web. It was subsequently standardized by the International Electrotechnical Commission (IEC) as IEC 61966-2-1:1999. sRGB is the current defined standard colorspace for the web, and it is usually the assumed colorspace for images that are neither tagged for a colorspace nor have an embedded color profile. sRGB essentially codifies the display specifications for the computer monitors in use at that time, which greatly aided its acceptance. sRGB uses the same color primaries and white point as ITU-R BT.709 standard for HDTV, a transfer function (or gamma) compatible with the era's CRT displays, and a viewing environment designed to match typical home and office viewing conditions. An amendment of the IEC 61966-2-1 standard document that defines sRGB includes the definition of a number of variants including sYCC, which i ...

Mirror
A mirror or looking glass is an object that Reflection (physics), reflects an image. Light that bounces off a mirror will show an image of whatever is in front of it, when focused through the lens of the eye or a camera. Mirrors reverse the direction of the image in an equal yet opposite angle from which the light shines upon it. This allows the viewer to see themselves or objects behind them, or even objects that are at an angle from them but out of their field of view, such as around a corner. Natural mirrors have existed since prehistoric times, such as the surface of water, but people have been manufacturing mirrors out of a variety of materials for thousands of years, like stone, metals, and glass. In modern mirrors, metals like silver or aluminium are often used due to their high reflectivity, applied as a thin coating on glass because of its naturally smooth and very Hardness (materials science), hard surface. A mirror is a Wave (physics), wave reflector. Light consis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold Leaf
Gold leaf is gold that has been hammered into thin sheets (usually around 0.1 µm thick) by goldbeating and is often used for gilding. Gold leaf is available in a wide variety of karats and shades. The most commonly used gold is 22-karat yellow gold. Gold leaf is a type of metal leaf, but the term is rarely used when referring to gold leaf. The term ''metal leaf'' is normally used for thin sheets of metal of any color that do not contain any real gold. Pure gold is 24 karat. Real, yellow gold leaf is approximately 91.7% pure (i.e. 22-karat) gold. Silver-colored white gold is about 50% pure gold. Layering gold leaf over a surface is called gold leafing or gilding. Traditional water gilding is the most difficult and highly regarded form of gold leafing. It has remained virtually unchanged for hundreds of years and is still done by hand. In art Gold leaf is sometimes used in art in a "raw" state, without a gilding process. In cultures including the European Bronze Age i ...

Catherine Palace
The Catherine Palace (russian: Екатерининский дворец, ) is a Rococo palace in Tsarskoye Selo (Pushkin), 30 km south of St. Petersburg, Russia. It was the summer residence of the Russian tsars. The Palace is part of the World Heritage Site Saint Petersburg and Related Groups of Monuments. History Following the Great Northern War, Russia recovered the farm called Saari Mojs (a high place) or Sarskaya Myza, which resided on a hill 65 m in elevation. In 1710, Peter the Great gave the estate to his wife Catherine I, the village of which was initially called Sarskoye Selo, and then finally Tsarskoye Selo (Tsar's Village). In 1723, Catherine I's Stone Palace, designed by Johann Friedrich Braunstein and built by Johann Ferster, replaced the original wooden house. This was a two-storey sixteen-room building, with state chambers finished in polished alabaster, while the upper one included Gobelin tapestry. The southeast portion of the estate included a gard ...

Amber Room
The Amber Room ( rus, Янтарная комната, r=Yantarnaya Komnata, german: Bernsteinzimmer, pl, Bursztynowa komnata) was a chamber decorated in amber panels backed with gold leaf and mirrors, located in the Catherine Palace of Tsarskoye Selo near Saint Petersburg. Constructed in the 18th century in Prussia, the room was dismantled and eventually disappeared during World War II. Before its loss, it was considered an " Eighth Wonder of the World". A reconstruction was made, starting in 1979 and completed and installed in the Catherine Palace in 2003. The Amber Room was intended in 1701 for the Charlottenburg Palace, in Berlin, Prussia, but was eventually installed at the Berlin City Palace. It was designed by German baroque sculptor Andreas Schlüter and Danish amber craftsman Gottfried Wolfram. Schlüter and Wolfram worked on the room until 1707, when work was continued by amber masters Gottfried Turau and Ernst Schacht from Danzig (Gdańsk). It remained in Berli ...

Cathode Ray Tube
A cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, which emit electron beams that are manipulated to display images on a phosphorescent screen. The images may represent electrical waveforms (oscilloscope), pictures ( television set, computer monitor), radar targets, or other phenomena. A CRT on a television set is commonly called a picture tube. CRTs have also been used as memory devices, in which case the screen is not intended to be visible to an observer. The term '' cathode ray'' was used to describe electron beams when they were first discovered, before it was understood that what was emitted from the cathode was a beam of electrons. In CRT television sets and computer monitors, the entire front area of the tube is scanned repeatedly and systematically in a fixed pattern called a raster. In color devices, an image is produced by controlling the intensity of each of three electron beams, one for each additive primary color (red, green, ...

VT220
The VT220 is a computer terminal introduced by Digital Equipment Corporation (DEC) in November 1983. The VT240 added monochrome ReGIS vector graphics support to the base model, while the VT241 did the same in color. The 200 series replaced the successful VT100 series, providing more functionality in a much smaller unit with a much smaller and lighter keyboard. Like the VT100, the VT200 series implemented a large subset of ANSI X.364. Among its major upgrades was a number of international character sets, as well as the ability to define new character sets. The VT200 series was extremely successful in the market. Released at $795, the VT220 offered features, packaging and price that no other serial terminal could compete with at the time. In 1986, DEC shipped 165,000 units, giving them a 42% market share, double that of the closest competitor, Wyse. Competitors adapted by introducing similar models at lower prices, leading DEC to do the same by releasing the less-expensive $545 ...

Digital Equipment Corporation
Digital Equipment Corporation (DEC ), using the trademark Digital, was a major American company in the computer industry from the 1960s to the 1990s. The company was co-founded by Ken Olsen and Harlan Anderson in 1957. Olsen was president until forced to resign in 1992, after the company had gone into precipitous decline. The company produced many different product lines over its history. It is best known for the work in the minicomputer market starting in the mid-1960s. The company produced a series of machines known as the PDP line, with the PDP-8 and PDP-11 being among the most successful minis in history. Their success was only surpassed by another DEC product, the late-1970s VAX "supermini" systems that were designed to replace the PDP-11. Although a number of competitors had successfully competed with Digital through the 1970s, the VAX cemented the company's place as a leading vendor in the computer space. As microcomputers improved in the late 1980s, especially wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
