Shades Of Cyan
The color cyan, a greenish-blue, has notable tints and shades. It is one of the subtractive primary colors along with magenta, and yellow. The first recorded use of ''cyan blue'' as a color name was in 1879 ("cyan blue" being the name used for "cyan" in the 19th century). Cyan in printing and the web colors cyan and aqua Process cyan In color printing, the shade of cyan called process cyan or pigment cyan is one of the three primary pigment colors which, along with yellow and magenta, constitute the three subtractive primary colors of pigment. (The secondary colors of pigment are blue, green, and red.) As such, the CMYK printing process was invented in the 1890s, when newspapers began to publish color comic strips. Process cyan is not an RGB color, and there is no fixed conversion from CMYK primaries to RGB. Different formulations are used for printer's ink, so there can be variations in the printed color that is pure cyan ink. A typical formulation of ''process cyan'' is ...

Cyan
Cyan () is the color between green and blue on the visible spectrum of light. It is evoked by light with a predominant wavelength between 490 and 520 nm, between the wavelengths of green and blue. In the subtractive color system, or CMYK color model, which can be overlaid to produce all colors in paint and color printing, cyan is one of the primary colors, along with magenta and yellow. In the additive color system, or RGB color model, used to create all the colors on a computer or television display, cyan is made by mixing equal amounts of green and blue light. Cyan is the complement of red; it can be made by the removal of red from white. Mixing red light and cyan light at the right intensity will make white light. Colors in the cyan color range are teal, turquoise, electric blue, aquamarine, and others described as blue-green. Etymology and terminology Its name is derived from the Ancient Greek word ''kyanos'' (κύανος), meaning "dark blue enamel, Lapis lazuli". It ...

Web Color
Web colors are colors used in Web design, displaying web pages on the World Wide Web, and the methods for describing and specifying those colors. Colors may be specified as an RGB color model, RGB triplet or in hexadecimal format (a ''hex triplet'') or according to their common English names 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 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.

American Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by states that had seceded. The central cause of the war was the dispute over whether slavery would be permitted to expand into the western territories, leading to more slave states, or be prevented from doing so, which was widely believed would place slavery on a course of ultimate extinction. Decades of political controversy over slavery were brought to a head by the victory in the 1860 U.S. presidential election of Abraham Lincoln, who opposed slavery's expansion into the west. An initial seven southern slave states responded to Lincoln's victory by seceding from the United States and, in 1861, forming the Confederacy. The Confederacy seized U.S. forts and other federal assets within their borders. Led by Confederate President Jefferson Davis, ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Azure (heraldry)
In heraldry, azure ( , ) is the tincture with the colour blue, and belongs to the class of tinctures called "colours". In engraving, it is sometimes depicted as a region of horizontal lines or else is marked with either az. or b. as an abbreviation. The term azure shares origin with the Spanish word "azul", which refers to the same color, deriving from hispanic Arabic ''lazawárd'' the name of the deep blue stone now called lapis lazuli. The word was adopted into Old French by the 12th century, after which the word passed into use in the blazon of coats of arms. As an heraldic colour, the word ''azure'' means "blue", and reflects the name for the colour in the language of the French-speaking Anglo-Norman nobles following the Norman Conquest of England. A wide range of colour values is used in the depiction of azure in armory and flags, and in common usage it is often referred to simply as 'blue'. In addition to the standard blue tincture called azure, there is a lighter blue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heraldry
Heraldry is a discipline relating to the design, display and study of armorial bearings (known as armory), as well as related disciplines, such as vexillology, together with the study of ceremony, rank and pedigree. Armory, the best-known branch of heraldry, concerns the design and transmission of the heraldic achievement. The achievement, or armorial bearings usually includes a coat of arms on a shield, helmet and crest, together with any accompanying devices, such as supporters, badges, heraldic banners and mottoes. Although the use of various devices to signify individuals and groups goes back to antiquity, both the form and use of such devices varied widely, as the concept of regular, hereditary designs, constituting the distinguishing feature of heraldry, did not develop until the High Middle Ages. It is often claimed that the use of helmets with face guards during this period made it difficult to recognize one's commanders in the field when large armies gathered together ...

Tincture (heraldry)
Tincture is the limited palette of colours and patterns used in heraldry. The need to define, depict, and correctly blazon the various tinctures is one of the most important aspects of heraldic art and design. Development and history The use of tinctures dates back to the formative period of European heraldry in the twelfth and thirteenth centuries. The range of tinctures and the manner of depicting and describing them has evolved over time, as new variations and practices have developed. The basic scheme and rules of applying the heraldic tinctures dates back to the 12th century. The earliest surviving coloured heraldic illustrations, from the mid-thirteenth century, show the standardized usage of two metals, five colours, and two furs. Since that time, the great majority of heraldic art has employed these nine tinctures. Over time, variations on these basic tinctures were developed, particularly with respect to the furs. Authorities differ as to whether these variations shou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bleu Celeste
Bleu celeste (, "sky blue") is a rarely occurring and non-standard tincture in heraldry (not being one of the seven main colours or metals or the three ''staynard colours''). This tincture is sometimes also called ciel or simply celeste. It is depicted in a lighter shade than the range of shades of the more traditional tincture azure, which is the standard blue used in heraldry. Generally considered to be European rather than English or Scottish, after the First World War it started to appear in England in arms and badges relating to the Royal Air Force, though it is still doubtful if any more than a dozen examples could be found in British heraldry, and most British heralds consider it unheraldic. While in the post-World War I period bleu-celeste is depicted as a darker shade, in prior times it was depicted as very light, and has even been treated as a metal, as azure charges have been placed on a bleu celeste field, and ''vice versa''. Regardless, ''bleu celeste'' is st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
