Red
–
Red is the color at the longer-wavelengths end of the spectrum of visible light next to orange, at the opposite end from violet. Red color has a predominant light wavelength of roughly 620–740 nanometers, light with a longer wavelength than red but shorter than terahertz radiation and microwave is called infrared. Red is one of the secondary colors, resulting from the combination of yellow. Traditionally, it was viewed as a primary colour, along with yellow and blue, in the RYB color space and traditional color wheel formerly used by painters. Reds can vary in shade from light pink to very dark maroon or burgundy. Red is the color of cyan. In nature, the red color of blood comes from hemoglobin, the red color of the Grand Canyon and other geological features is caused by hematite or red ochre, both forms of iron oxide. It also causes the red color of the planet Mars, the color of autumn leaves is caused by pigments called anthocyanins, which are produced towards the end of summer, when the green chlorophyll is no longer produced. One to two percent of the population has red hair, the color is produced by high levels of the reddish pigment pheomelanin. Since red is the color of blood, it has historically been associated with sacrifice, danger, modern surveys in the United States and Europe show red is also the color most commonly associated with heat, activity, passion, sexuality, anger, love and joy. In China, India and many other Asian countries it is the color of symbolizing happiness, since the 19th century, red has also been associated with socialism and communism. The word red is derived from the Old English rēad, the word can be further traced to the Proto-Germanic rauthaz and the Proto-Indo European root rewdʰ-. In Sanskrit, the word means red or blood. In the Akkadian language of Ancient Mesopotamia and in the modern Inuit language of Inuit, the words for colored in Latin and Spanish both also mean red. In Portuguese the word for red is vermelho, which comes from Latin vermiculus, in the Russian language, the word for red, Кра́сный, comes from the same old Slavic root as the words for beautiful—красивый and excellent—прекрасный. Thus Red Square in Moscow, named long before the Russian Revolution, in heraldry, the word gules is used for red. Red can vary in hue from orange-red to violet-red, and for each hue there is a variety of shades and tints. Red hematite powder was found scattered around the remains at a grave site in a Zhoukoudian cave complex near Beijing

White
–
White is an achromatic color, a color without hue. An incoming light to the eye that stimulates all its three types of color sensitive cone cells in nearly equal amounts results in white. White is one of the most common colors in nature, the color of sunlight, snow, milk, chalk, limestone, in many cultures white represents or signifies purity, innocence, and light, and is the symbolic opposite of black, or darkness. According to surveys in Europe and the United States, white is the color most often associated with perfection, the good, honesty, cleanliness, the beginning, the new, neutrality, and exactitude. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, in the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity, the widows of kings dressed in white rather than black as the color of mourning. It was also used in 20th century modern architecture as a symbol of modernity, simplicity. White is an important color for almost all world religions, the Pope, the head of the Roman Catholic Church, has worn white since 1566, as a symbol of purity and sacrifice. In Islam, and in the Shinto religion of Japan, it is worn by pilgrims, in Western cultures and in Japan, white is the most common color for wedding dresses, symbolizing purity and virginity. In many Asian cultures, white is also the color of mourning, the white color on television screens and computer monitors is created with the RGB color model by mixing red, green and blue light at equal intensities. The word white continues Old English hwīt, ultimately from a Common Germanic *χwītaz also reflected in OHG wîz, ON hvítr, the root is ultimately from Proto-Indo-European language *kwid-, surviving also in Sanskrit śveta to be white or bright and Slavonic světŭ light. The Icelandic word for white, hvítur, is derived from the Old Norse form of the word hvítr. Common Germanic also had the word *blankaz, borrowed into Late Latin as *blancus, the antonym of white is black. Some non-European languages have a variety of terms for white. The Inuit language has seven different words for seven different nuances of white, Japanese has six different words, depending upon brilliance or dullness, or if the color is inert or dynamic. White was one of the first colors used in art, the Lascaux Cave in France contains drawings of bulls and other animals drawn by paleolithic artists between 18,000 and 17,000 years ago. Paleolithic artists used calcite or chalk, they sometimes as a background, sometimes as a highlight, along with charcoal and red, in ancient Egypt, white was connected with the goddess Isis. The priests and priestesses of Isis dressed only in white linen, in Greece and other ancient civilizations, white was often associated with mothers milk. In Greek mythology, the chief god Zeus was nourished at the breast of the nymph Amalthea, in the Talmud, milk was one of four sacred substances, along with wine, honey, and the rose

Black
–
Black is the darkest color resulting from the absence or complete absorption of light. Like white and grey, it is a color, literally a color without hue. It is one of the four colors in the CMYK color model, along with cyan, yellow. Black is often used to represent darkness, it is the symbolic opposite of white, Black was one of the first colors used by artists in neolithic cave paintings. In the 14th century, it began to be worn by royalty and it became the color worn by English romantic poets, businessmen and statesmen in the 19th century, and a high fashion color in the 20th century. In the Roman Empire, it became the color of mourning, according to surveys in Europe and North America, it is the color most commonly associated with mourning, the end, secrets, magic, force, violence, evil, and elegance. More distant cognates include Latin flagrare, and Ancient Greek phlegein, the Ancient Greeks sometimes used the same word to name different colors, if they had the same intensity. Kuanos could mean both dark blue and black, the Ancient Romans had two words for black, ater was a flat, dull black, while niger was a brilliant, saturated black. Ater has vanished from the vocabulary, but niger was the source of the country name Nigeria the English word Negro, old High German also had two words for black, swartz for dull black and blach for a luminous black. These are parallelled in Middle English by the terms swart for dull black, swart still survives as the word swarthy, while blaek became the modern English black. In heraldry, the used for the black color is sable, named for the black fur of the sable. Black was one of the first colors used in art, the Lascaux Cave in France contains drawings of bulls and other animals drawn by paleolithic artists between 18,000 and 17,000 years ago. They began by using charcoal, and then made more vivid black pigments by burning bones or grinding a powder of manganese oxide, for the ancient Egyptians, black had positive associations, being the color of fertility and the rich black soil flooded by the Nile. It was the color of Anubis, the god of the underworld, who took the form of a black jackal, and offered protection against evil to the dead. For the ancient Greeks, black was also the color of the underworld, separated from the world of the living by the river Acheron and those who had committed the worst sins were sent to Tartarus, the deepest and darkest level. In the center was the palace of Hades, the king of the underworld, Black was one of the most important colors used by ancient Greek artists. In the 6th century BC, they began making pottery and later red figure pottery. In black-figure pottery, the artist would paint figures with a clay slip on a red clay pot

War flag
–
A war flag, also known as a military flag or a battle flag, is a variant of a national flag for use by a countrys military forces when on land. The nautical equivalent is a naval ensign, under the strictest sense of the term, few countries today currently have proper war flags, most preferring to use instead their state flag or standard national flag for this purpose. And either victory, or else a grave, field signs were used in early warfare at least since the Bronze Age. The word standard itself is from an Old Frankish term for a field sign, the use of flags as field signs apparently emerges in Asia, during the Iron Age, possibly in either China or India. Early field signs that include, but are not limited to a flag, are also called vexilloid or flag-like, the Roman Vexillum itself is also flag-like in the sense that it was suspended from a horizontal crossbar as opposed to a simple flagpole. Use of simple flags as military ensigns becomes common during the medieval period, the maritime flag also develops in the medieval period. The medieval Japanese Sashimono carried by foot-soldiers are a parallel development, some medieval free cities or communes did not have coats of arms, and used war flags that were not derived from a coat of arms. Thus, the city of Lucerne used a flag as a field sign from the mid 13th century.

Tricolour (flag)
–
A tricolour or tricolor is a type of flag or banner design with a triband design which originated in the 16th century as a symbol of republicanism, liberty or indeed revolution. One of the most famous tricolour, known as Le Tricolore, is the flag of France adopted in the French Revolution. The green-white-red tricolour remained a symbol of republicanism throughout the 19th century and was adopted as national flag by a number of following the Revolutions of 1848. It was also adopted by the Kingdom of Sardinia and this flag was a symbol of opposition against the German Kleinstaaterei and the desire for German Unification. It was at first illegal in the German Confederation, but was adopted as the flag at the Frankfurt Parliament of 1848/9. The flag of Belgium was introduced in a context, in 1831. The first national flag of the New World inspired by this symbolism was the flag of Mexico, the Pan-Arab colors adopted in Arab nationalism 1916 are a comparable concept, even though they combine four, not three, colours. The Indian independence movement in 1931 also adopted a tricolour in the symbolism of national unification and republican self-rule. In 1999, a red, green, and blue tricolour was proposed as the Flag of Mars, the design symbolizes liberty, and also the terraforming of Mars by humanity from a red planet to a green one, and eventually an Earth-like blue one.

Farouk of Egypt
–
King Farouk was the tenth ruler of Egypt from the Muhammad Ali Dynasty and the penultimate King of Egypt and the Sudan, succeeding his father, Fuad I, in 1936. His full title was His Majesty Farouk I, by the grace of God, King of Egypt and he was overthrown in the 1952 military coup détat and forced to abdicate in favor of his infant son Ahmed Fuad, who succeeded him as Fuad II. He died in exile in Italy and his sister Princess Fawzia Fuad was the first wife and Queen consort of the Shah of Iran Mohammad Reza Pahlavi. King Farouk was born His Sultanic Highness Prince Farouk bin Fuad at Abdeen Palace, Cairo, the eldest child of Sultan Fuad I of Egypt and Sudan, King Farouk of Egypt was of 10/16 Circassian, 3/16 Turkish, 2/16 French and 1/16 Albanian descent. In addition to his sisters, Fawzia, Faiza, Faika and Fathia, before his fathers death, he was educated at the Royal Military Academy, Woolwich, England. It is said that he ate 600 oysters a week, in 1951, he bought the pear-shaped 94-carat Star of the East Diamond and a fancy-coloured oval-cut diamond from jeweler Harry Winston. He was most popular in his years and the nobility largely celebrated him. Farouks accession initially was encouraging for the populace and nobility, due to his youth, however, the situation was not the same with some Egyptian politicians and elected government officials, with whom Farouk quarreled frequently, despite their loyalty in principle to his throne. There was also the issue of the continuous British involvement in the Egyptian government, during the hardships of the Second World War, criticism was leveled at Farouk for his lavish lifestyle. His decision not to put out the lights at his palace in Alexandria when the city was blacked out because of German and Italian bombing was deemed offensive by the Egyptian people. This was a large contrast to the British royal family back in England who were known to have an opposite reaction to the bombings near their home. In addition, Farouk was known for harboring certain Axis sympathies, on the night of 4 February 1942, British troops and tanks surrounded Abdeen Palace in Cairo and Lampson presented Farouk with an ultimatum. Farouk capitulated, and Nahhas formed a government shortly thereafter, with this, Farouks popularity seemed to decrease significantly, especially with the rise of Arab nationalism. Many of the people in the country view him a puppet to the powers of the West, Farouk declared war on the Axis Powers only under heavy British pressure in 1945, long after the fighting in Egypts Western Desert had ceased. On 17 October 1951 the Egyptian government got Parliamentary approval to cancel the 1936 Anglo-Egyptian Treaty, as a result, the British forces in the Suez Canal were considered occupation forces and king Farouk was declared King of Egypt and Sudan. This title was not recognised by many countries, and Egypt entered diplomatic debates as well as political unrest. Farouk is also reported as having said The whole world is in revolt, soon there will be only five Kings left — the King of England, the King of Spades, the King of Clubs, the King of Hearts, and the King of Diamonds. Public discontent against Farouk rose to new levels, finally, on 23 July 1952, the Free Officers, led by Muhammad Naguib and Gamal Abdel Nasser, staged a military coup that launched the Egyptian Revolution of 1952

RGB color model
–
The RGB color model is an additive color model in which red, green and blue 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 primary colors, red, green and blue. Before the electronic age, the RGB color model already had a theory behind it. Thus an RGB value does not define the same color across devices without some kind of color management, typical RGB input devices are color TV and video cameras, image scanners, video games, and digital cameras. Typical RGB output devices are TV sets of technologies, computer and mobile phone displays, video projectors, multicolor LED displays. Color printers, on the hand are not RGB devices. This article discusses concepts common to all the different color spaces that use the RGB color model, to form a color with RGB, three light beams must be superimposed. Each of the three beams is called a component of color, and each of them can have an arbitrary intensity, from fully off to fully on. The RGB color model is additive in the sense that the three beams are added together, and their light spectra add, wavelength for wavelength. This is essentially opposite to the color model that applies to paints, inks, dyes. When the intensities for all the components are the same, the result is a shade of gray, darker or lighter depending on the intensity. When the intensities are different, the result is a colorized hue, a secondary color is formed by the sum of two primary colors of equal intensity, cyan is green+blue, magenta is red+blue, and yellow is red+green. The RGB color model itself does not define what is meant by red, green and blue colorimetrically, and so the results of mixing them are not specified as absolute, but relative to the primary colors. When the exact chromaticities of the red, green and blue primaries are defined, the normal three kinds of light-sensitive photoreceptor cells in the human eye respond most to yellow, green, and violet light. As an example, suppose that light in the range of wavelengths enters the eye. Light of these wavelengths would activate both the medium and long wavelength cones of the retina, but not equally—the long-wavelength cells will respond more, the difference in the response can be detected by the brain, and this difference is the basis of our perception of orange. Thus, the appearance of an object results from light from the object entering our eye and stimulating the different cones simultaneously. The first experiments with RGB in early color photography were made in 1861 by Maxwell himself, to reproduce the color photograph, three matching projections over a screen in a dark room were necessary

CMYK color model
–
The CMYK color model is a subtractive color model, used in color printing, and is also used to describe the printing process itself. CMYK refers to the four used in some color printing, cyan, magenta, yellow. Though it varies by print house, press operator, press manufacturer, the K in CMYK stands for key because in four-color printing, cyan, magenta and yellow printing plates are carefully keyed, or aligned, with the key of the black key plate. Some sources suggest that the K in CMYK comes from the last letter in black and was chosen because B already means blue. Some sources claim this explanation, although useful as a mnemonic, is incorrect, 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 because inks subtract brightness from white. In additive color models such as RGB, white is the combination of all primary colored lights. In the CMYK model, it is the opposite, white is the color of the paper or other background. To save cost on ink, and to produce deeper black tones, unsaturated and dark colors are produced by using black ink instead of the combination of cyan, magenta, with halftoning, a full continuous range of colors can be produced. To improve print quality and reduce moiré patterns, the screen for each color is set at a different angle. Common reasons for using black ink include, In traditional preparation of color separations, in some cases a black keyline was used when it served as both a color indicator and an outline to be printed in black. Because usually the black plate contained the keyline, the K in CMYK represents the keyline or black plate, also sometimes called the key plate. A combination of 100% cyan, magenta, and yellow inks soaks the paper with ink, making it slower to dry, causing bleeding, adding black ink absorbs more light and yields much better blacks. Using black ink is less expensive than using the corresponding amounts of colored inks. When a very dark area is desirable, a colored or gray CMY bedding is applied first, then a black layer is applied on top, making a rich, deep black. A black made with just CMY inks is sometimes called a composite black, the amount of black to use to replace amounts of the other ink is variable, and the choice depends on the technology, paper and ink in use. Processes called under color removal, under addition, and gray component replacement are used to decide on the final mix. CMYK or process color printing is contrasted with spot color printing, some printing presses are capable of printing with both four-color process inks and additional spot color inks at the same time

Sudan
–
Sudan, also known as North Sudan since South Sudans independence and officially the Republic of the Sudan, is a country in Northern Africa. It is the third largest country in Africa, the River Nile divides the country into eastern and western halves. Before the Sudanese Civil War, South Sudan was part of Sudan, Sudan was home to numerous ancient civilizations, such as the Kingdom of Kush, Kerma, Nobatia, Alodia, Makuria, Meroë and others, most of which flourished along the Nile. During the pre-dynastic period Nubia and Nagadan Upper Egypt were identical, by virtue of its proximity to Egypt, the Sudan participated in the wider history of the Near East inasmuch as it was Christianized by the 6th century, and Islamized in the 15th. As a result of Christianization, the Old Nubian language stands as the oldest recorded Nilo-Saharan language, Sudan was the largest country in Africa and the Arab world until 2011, when South Sudan separated into an independent country, following an independence referendum. Sudan is now the third largest country in Africa and also the third largest country in the Arab world and its capital is Khartoum, the political, cultural and commercial centre of the nation. It is a representative democratic federal republic. The politics of Sudan are regulated by an organization called the National Assembly. The Sudanese legal system is based on Islamic law, the countrys place name Sudan is a name given to a geographical region to the south of the Sahara, stretching from Western Africa to eastern Central Africa. The name derives from the Arabic bilād as-sūdān, or the lands of the Blacks, during the fifth millennium BC migrations from the drying Sahara brought neolithic people into the Nile Valley along with agriculture. The population that resulted from this cultural and genetic mixing developed social hierarchy over the centuries become the Kingdom of Kush at 1700 BC. The Kingdom of Kush was an ancient Nubian state centered on the confluences of the Blue Nile and White Nile, and the Atbarah River and it was established after the Bronze Age collapse and the disintegration of the New Kingdom of Egypt, centered at Napata in its early phase. After King Kashta invaded Egypt in the eighth century BC, the Kushite kings ruled as pharaohs of the Twenty-fifth Dynasty of Egypt for a century before being defeated and driven out by the Assyrians. At the height of their glory, the Kushites conquered an empire that stretched from what is now known as South Kordofan all the way to the Sinai, pharaoh Piye attempted to expand the empire into the Near East, but was thwarted by the Assyrian king Sargon II. Sennacheribs successor Esarhaddon went further, and invaded Egypt itself, deposing Taharqa, Taharqa fled back to his homeland where he died two years later. Egypt became an Assyrian colony, however, king Tantamani, after succeeding Taharqa, Esarhaddon died while preparing to leave the Assyrian capital of Nineveh in order to eject him. However, his successor Ashurbanipal sent an army into southern Egypt and routed Tantamani. During Classical Antiquity, the Nubian capital was at Meroë, in ancient Greek geography, the Meroitic kingdom was known as Ethiopia

Egyptian Army
–
The Egyptian Army is the largest service branch within the Egyptian Armed Forces, and is the largest army in Africa. The modern army was established during the reign of Muhammad Ali Pasha, the Egyptian army was also engaged heavily in the protracted North Yemen Civil War, and the brief Libyan-Egyptian War in July 1977. As of 2014, the army has a strength of 310,000 soldiers, of which, approximately 90. For most parts of its history, ancient Egypt was unified under one government. The main military concern for the nation was to keep enemies out, the arid plains they wanted to get rid of and deserts surrounding Egypt were inhabited by nomadic tribes who occasionally tried to raid or settle in the fertile Nile river valley. Nevertheless, the expanses of the desert formed a barrier that protected the river valley and was almost impossible for massive armies to cross. The Egyptians built fortresses and outposts along the borders east and west of the Nile Delta, in the Eastern Desert, small garrisons could prevent minor incursions, but if a large force was detected a message was sent for the main army corps. Most Egyptian cities lacked city walls and other defenses, the history of ancient Egypt is divided into three kingdoms and two intermediate periods. During the three kingdoms Egypt was unified under one government, during the intermediate periods government control was in the hands of the various nomes and various foreigners. The geography of Egypt served to isolate the country and allowed it to thrive and this circumstance set the stage for many of Egypts military conquests. They weakened their enemies by using small projectile weapons, like bows and arrows and they also had chariots which they used to charge at the enemy. Following his seizure of power in Egypt, and declaration of himself as khedive of the country, Muhammad Ali Pasha set about establishing a bona fide Egyptian military. Prior to his rule, Egypt had been governed by the Ottoman Empire, to further this aim, he brought in European weapons and expertise, and built an army that defeated the Ottoman Sultan, wresting control from the Porte of the Levant, and Hejaz. Egypt was involved in the long-running 1881–99 Mahdist War in the Sudan, during Muhammad Ali Pashas reign, the Egyptian army became a much more strictly regimented and professional army. The recruits were separated from daily life and a sense of the impersonal of law was imposed. Muhammad Ali Pasha previously attempted to create an army of Sudanese slaves and Mamluks, instead, the Pasha enforced conscription in 1822 and the new military recruits were mostly Egyptian farmers, also known as fellah. Because of harsh military practices, the 130,000 soldiers conscripted in 1822 revolted in the south in 1824, the Pashas goal was to create military order through indoctrination by two new major key practices, isolation and surveillance. In previous times, the wives and family were allowed to follow the army wherever they camped and this was no longer the case
