Flag Of Qatar
The flag of Qatar () is in the ratio of 11:28. It is maroon with a broad white serrated band (nine white points) on the Hoist (flag), hoist side. It was adopted shortly before the country declared independence from the United Kingdom on 3 September 1971. The triangle edges represent Qatar as the 9th " reconciled emirate". The flag is similar to the flag of Bahrain, which has fewer points, a 3:5 proportion, and a red colour instead of maroon. Qatar's flag is the only national flag having a width more than twice its height. History Qatar's historic flag was plain red, in correspondence with the red banner traditionally used by the Khawarij, Kharjite leader Qatari ibn al-Fuja'a. In the 19th century, the country modified its entirely red flag with the addition of a white vertical stripe at the hoist to suit the British directive. After this addition, Sheikh Mohammed bin Thani officially adopted a patterned purple-red and white flag which bore a strong resemblance to its modern derivat ...

RGB Color Model
The RGB color model is an additive color, additive color model in which the red, green, and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue. The main purpose of the RGB color model is for the sensing, representation, and display of images in electronic systems, such as televisions and computers, though it has also been used in conventional photography and Light-emitting diode#RGB systems, colored lighting. Before the electronic age, the RGB color model already had a solid theory behind it, based in Trichromacy, human perception of colors. RGB is a ''device-dependent'' color model: different devices detect or reproduce a given RGB value differently, since the color elements (such as phosphors or dyes) and their response to the individual red, green, and blue levels vary from manufacturer to manufacturer, or even in the ...

Web Colors
Web colors are colors used in Web design, displaying web pages on the World Wide Web; they can be described by way of three methods: a color may be specified as an RGB color model, RGB triplet, in hexadecimal format (a ''hex triplet'') or according to its common English name 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 CSS, 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.

CMYK
The CMYK color model (also known as process color, or four color) is a subtractive color model, based on the CMY color model, used in color printing, and is also used to describe the printing process itself. The abbreviation ''CMYK'' refers to the four ink plates used: cyan, magenta, yellow, and key (most often black). The CMYK model works by partially or entirely masking colors on a lighter, usually white, background. The ink reduces the light that would otherwise be reflected. Such a model is called ''subtractive'', as inks ''subtract'' some colors from white light; in the CMY model, white light minus red leaves cyan, white light minus green leaves magenta, and white light minus blue leaves yellow. In additive color models, such as RGB, white is the ''additive'' combination of all primary colored lights, and black is the absence of light. In the CMYK model, it is the opposite: white is the natural color of the paper or other background, and black results from a ful ...

RAL Color Standard
RAL is a colour management system used in Europe that is created and administered by the German (RAL non-profit LLC), which is a subsidiary of the German . In colloquial speech, RAL refers to the RAL Classic system, mainly used for varnish and powder coating, but now plastics as well. Approved RAL products are provided with a hologram to make unauthorised versions difficult to produce. Imitations may show different hue and colour when observed under various light sources. RAL colour space system RAL Classic In 1927, the German group (Imperial Committee for Delivery and Quality Assurance) invented a collection of forty colours under the name of "RAL 840". Prior to that date, manufacturers and customers had to exchange samples to describe a tint, whereas from then on they would rely on numbers. In the 1930s, the numbers were changed uniformly to four digits and the collection was renamed to "RAL 840 R" (R for revised). Around 1940, the RAL colours were changed to the four-d ...

Sasanian Empire
The Sasanian Empire (), officially Eranshahr ( , "Empire of the Iranian peoples, Iranians"), was an List of monarchs of Iran, Iranian empire that was founded and ruled by the House of Sasan from 224 to 651. Enduring for over four centuries, the length of the Sasanian dynasty's reign over ancient Iran was second only to the directly preceding Arsacid dynasty of Parthia. Founded by Ardashir I, whose rise coincided with the decline of Arsacid influence in the face of both internal and external strife, the House of Sasan was highly determined to restore the legacy of the Achaemenid Empire by expanding and consolidating the Iranian nation's dominions. Most notably, after defeating Artabanus IV of Parthia during the Battle of Hormozdgan in 224, it began competing far more zealously with the neighbouring Roman Empire than the Arsacids had, thus sparking a new phase of the Roman–Iranian Wars. This effort by Ardashir's dynasty ultimately re-established Iran as a major power of late an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Al Khor Islands
Al Khor Island (), also known as Jazirat bin Ghanim or Purple Island, is an island located in the municipality of Al Khor on the northeast coast of Qatar. It accommodates the only archaeological site in the country attributable to the second millennium BC. There are four main periods of occupation on the island, dating from as early as to as late as 1900 AD. The island is best known for being the site of operation of a Kassite-controlled purple dye industry in the second millennium BC. It is one of the most popular tourist attractions in the country due to its lush mangrove forest and diverse landscape and ecology.

Kassites
The Kassites () were a people of the ancient Near East. They controlled Babylonia after the fall of the Old Babylonian Empire from until (short chronology). The Kassites gained control of Babylonia after the Hittite sack of Babylon in 1531 BC, and established a dynasty generally assumed to have been based first in that city, after a hiatus. Later rule shifted to the new city of Dur-Kurigalzu. By the time of Babylon's fall, the Kassites had already been part of the region for a century and a half, acting sometimes with Babylon's interests and sometimes against. There are records of Kassite and Babylonian interactions, in the context of military employment, during the reigns of Babylonian kings Samsu-iluna (1686 to 1648 BC), Abī-ešuh, and Ammī-ditāna. The origin and classification of the Kassite language, like the Sumerian language and Hurrian language, is uncertain, and, also like the two latter languages, has generated a wide array of speculation over the years, even ...

Shellfish
Shellfish, in colloquial and fisheries usage, are exoskeleton-bearing Aquatic animal, aquatic invertebrates used as Human food, food, including various species of Mollusca, molluscs, crustaceans, and echinoderms. Although most kinds of shellfish are harvested from Seawater, saltwater environments, some are found in freshwater. In addition, a few species of land crabs are eaten, for example ''Cardisoma guanhumi'' in the Caribbean. Shellfish are among the most common food allergy, food allergens. Despite the name, shell''fish'' are not fish. Most shellfish are Trophic level, low on the food chain and eat a diet composed primarily of phytoplankton and zooplankton. Many varieties of shellfish, and crustaceans in particular, are actually closely related to insects and arachnids; crustaceans make up one of the main Subphylum, subphyla of the phylum Arthropoda. Molluscs include cephalopods (squids, octopuses, cuttlefish) and bivalves (clams, oysters), as well as gastropods (aquatic spe ...
