Democracy is a system of government where the citizens exercise power by voting. In a direct democracy, the citizens as a whole form a governing body and vote directly on each issue. In a representative democracy the citizens elect representatives from among themselves; these representatives meet to form a governing body, such as a legislature. In a constitutional democracy the powers of the majority are exercised within the framework of a representative democracy, but the constitution limits the majority and protects the minority through the enjoyment by all of certain individual rights, e.g. freedom of speech, or freedom of association. "Rule of the majority" is sometimes referred to as democracy. Democracy is a system of processing conflicts in which outcomes depend on what participants do, but no single force controls what occurs and its outcomes; the uncertainty of outcomes is inherent in democracy, which makes all forces struggle for the realization of their interests, being the devolution of power from a group of people to a set of rules.
Western democracy, as distinct from that which existed in pre-modern societies, is considered to have originated in city-states such as Classical Athens and the Roman Republic, where various schemes and degrees of enfranchisement of the free male population were observed before the form disappeared in the West at the beginning of late antiquity. The English word dates back to the 16th century, from the older Middle French and Middle Latin equivalents. According to American political scientist Larry Diamond, democracy consists of four key elements: a political system for choosing and replacing the government through free and fair elections. Todd Landman draws our attention to the fact that democracy and human rights are two different concepts and that "there must be greater specificity in the conceptualisation and operationalization of democracy and human rights"; the term appeared in the 5th century BC to denote the political systems existing in Greek city-states, notably Athens, to mean "rule of the people", in contrast to aristocracy, meaning "rule of an elite".
While theoretically these definitions are in opposition, in practice the distinction has been blurred historically. The political system of Classical Athens, for example, granted democratic citizenship to free men and excluded slaves and women from political participation. In all democratic governments throughout ancient and modern history, democratic citizenship consisted of an elite class, until full enfranchisement was won for all adult citizens in most modern democracies through the suffrage movements of the 19th and 20th centuries. Democracy contrasts with forms of government where power is either held by an individual, as in an absolute monarchy, or where power is held by a small number of individuals, as in an oligarchy; these oppositions, inherited from Greek philosophy, are now ambiguous because contemporary governments have mixed democratic and monarchic elements. Karl Popper defined democracy in contrast to dictatorship or tyranny, thus focusing on opportunities for the people to control their leaders and to oust them without the need for a revolution.
No consensus exists on how to define democracy, but legal equality, political freedom and rule of law have been identified as important characteristics. These principles are reflected in all eligible citizens being equal before the law and having equal access to legislative processes. For example, in a representative democracy, every vote has equal weight, no unreasonable restrictions can apply to anyone seeking to become a representative, the freedom of its eligible citizens is secured by legitimised rights and liberties which are protected by a constitution. Other uses of "democracy" include that of direct democracy. One theory holds that democracy requires three fundamental principles: upward control, political equality, social norms by which individuals and institutions only consider acceptable acts that reflect the first two principles of upward control and political equality; the term "democracy" is sometimes used as shorthand for liberal democracy, a variant of representative democracy that may include elements such as political pluralism.
Roger Scruton argues that democracy alone cannot provide personal and political freedom unless the institutions of civil society are present. In some countries, notably in the United Kingdom which originated the Westminster system, the dominant principle is that of parliamentary sovereignty, while maintaining judicial independence. In the United States, separation of powers is cited as a central attribute. In India, parliamentary sovereignty is subject to the Constitution of India which includes judicial review. Though the term "democracy" is used in the context of a political state, the principles are applicable to private organisations. Majority rule is listed as a characteristic of democracy. Hence, democracy allows for political minorities to be oppressed by the "tyranny of the majority" in the absence of legal protections of individual or group rights. An essential part of an "ideal" representative democracy is competitive elections that are substantively and procedurally "fair," i.e. just and equitable
Nicaragua the Republic of Nicaragua, is the largest country in the Central American isthmus, bordered by Honduras to the northwest, the Caribbean to the east, Costa Rica to the south, the Pacific Ocean to the southwest. Managua is the country's capital and largest city and is the third-largest city in Central America, behind Tegucigalpa and Guatemala City; the multi-ethnic population of six million includes people of indigenous, European and Asian heritage. The main language is Spanish. Indigenous tribes on the Mosquito Coast speak English. Inhabited by various indigenous cultures since ancient times, the Spanish Empire conquered the region in the 16th century. Nicaragua gained independence from Spain in 1821; the Mosquito Coast followed a different historical path, with the English colonizing it in the 17th century and coming under the British rule, as well as some minor Spanish interludes in the 19th century. It became an autonomous territory of Nicaragua in 1860 and the northernmost part of it was transferred to Honduras in 1960.
Since its independence, Nicaragua has undergone periods of political unrest, dictatorship and fiscal crisis, leading to the Nicaraguan Revolution of the 1960s and 1970s and the Contra War of the 1980s. The mixture of cultural traditions has generated substantial diversity in folklore, cuisine and literature the latter given the literary contributions of Nicaraguan poets and writers, such as Rubén Darío. Known as the "land of lakes and volcanoes", Nicaragua is home to the second-largest rainforest of the Americas; the country has set a goal of 90% renewable energy by the year 2020. The biological diversity, warm tropical climate and active volcanoes make Nicaragua an popular tourist destination. There are two prevailing theories on; the first is that the name was coined by Spanish colonists based on the name Nicarao, the chieftain or cacique of a powerful indigenous tribe encountered by the Spanish conquistador Gil González Dávila during his entry into southwestern Nicaragua in 1522. This theory holds that the name Nicaragua was formed from Nicarao and agua, to reference the fact that there are two large lakes and several other bodies of water within the country.
However, as of 2002, it was determined that the cacique's real name was Macuilmiquiztli, which meant "Five Deaths" in the Nahuatl language, rather than Nicarao. The second theory is that the country's name comes from any of the following Nahuatl words: nic-anahuac, which meant "Anahuac reached this far", or "the Nahuas came this far", or "those who come from Anahuac came this far". Paleo-Americans first inhabited what is now known as Nicaragua as far back as 12,000 BCE. In pre-Columbian times, Nicaragua's indigenous people were part of the Intermediate Area, between the Mesoamerican and Andean cultural regions, within the influence of the Isthmo-Colombian area. Nicaragua's central region and its Caribbean coast were inhabited by Macro-Chibchan language ethnic groups, they had coalesced in Central America and migrated to present-day northern Colombia and nearby areas. They lived a life based on hunting and gathering, as well as fishing, performing slash-and-burn agriculture. At the end of the 15th century, western Nicaragua was inhabited by several different indigenous peoples related by culture to the Mesoamerican civilizations of the Aztec and Maya, by language to the Mesoamerican Linguistic Area.
The Chorotegas were Mangue language ethnic groups who had arrived in Nicaragua from what is now the Mexican state of Chiapas sometime around 800 CE. The Pipil-Nicarao people were a branch of Nahuas who spoke the Nahuat dialect, like the Chorotegas, they too had come from Chiapas to Nicaragua in 1200 CE. Prior to that, the Pipil-Nicaraos had been associated with the Toltec civilization. Both the Chorotegas and the Pipil-Nicaraos were from Mexico's Cholula valley, had migrated southward. Additionally, there were trade-related colonies in Nicaragua, set up by the Aztecs starting in the 14th century. In 1502, on his fourth voyage, Christopher Columbus became the first European known to have reached what is now Nicaragua as he sailed southeast toward the Isthmus of Panama. Columbus explored the Mosquito Coast on the Atlantic side of Nicaragua but did not encounter any indigenous people. 20 years the Spaniards returned to Nicaragua, this time to its southwestern part. The first attempt to conquer Nicaragua was by the conquistador Gil González Dávila, who had arrived in Panama in January 1520.
In 1522, González Dávila ventured into the area that became known as the Rivas Department of Nicaragua. It was there that he encountered an indigenous Nahua tribe led by a chieftain named Macuilmiquiztli, whose name has sometimes been erroneously referred to as "Nicarao" or "Nicaragua". At the time, the tribe's capital city was called Quauhcapolca. González Dávila had brought along two indigenous interpreters, taught the Spanish language, thus he was able to have a discourse with Macuilmiquiztli. After exploring and gathering gold in the fertile western valleys, González Dávila and his men were attacked and driven off by the Chorotega, led by the chieftain Diriangen; the Spanish attempted to convert the tribes to Christianity. The first Spanish permanent settlements were founded in 1524; that year, the conquistador
José Manuel Zelaya Rosales is a Honduran politician, President of Honduras from 27 January 2006 until 28 June 2009. He is the eldest son of a wealthy businessman, inherited his father's nickname "Mel". Before entering politics he was involved in his family's timber businesses. Elected as a liberal, Zelaya shifted to the political left during his presidency, forging an alliance with the ALBA. On 28 June 2009, during the 2009 Honduran constitutional crisis, he was seized by the military and sent to Costa Rica in a coup d'état. On 21 September 2009 he returned to Honduras clandestinely and resurfaced in the Brazilian embassy in Tegucigalpa. In 2010 he left Honduras for an exile that lasted more than a year, he now represents Honduras as a deputy of the Central American Parliament. Since January 1976 Zelaya has been married to Xiomara Castro de Zelaya, a presidential candidate in the 2013 general election but lost to Juan Orlando Hernández; the surname'Zelaya' is a word from the Basque language, which means'field'.
Zelaya was born the eldest of four children in Olancho. Two of his brothers remain alive. Zelaya's mother, Ortensia Rosales de Zelaya, has been described as his best campaigner, his family first lived in Copán they moved east to Catacamas, Olancho. He attended Niño Jesús de Praga y Luis Landa elementary school and the Instituto Salesiano San Miguel, he began his university studies in civil engineering, but left in 1976 with 11 courses completed, for agriculture and the forestry sector. He was forced to take over the family business by the arrest of his father José Manuel Zelaya Ordoñez, implicated in the murders known as "Slaughter of the Horcones." These murders involved Mayor José Enrique Chinchilla, Sub-Lieutenant Benjamín Plata, José Manuel Zelaya Ordoñez and Carlos Bhar. They were taken to the Central Prison, he has engaged in business activities that including timber and cattle, handed down to him by his late father. He is now a landowner in Olancho. In 1987, Zelaya became manager of the Honduran Council of Private Enterprise, as well as of the National Association of Wood Processing Enterprises.
The COHEP occupies a important role in Honduran politics, as the Constitution delineates that the organization elects one of the seven members of the Nominating Board that proposes nominees to the Supreme Court of Honduras. Zelaya's father got a 20-year prison sentence for his role in the 1975 Los Horcones massacre, which took place on the Zelaya family ranch, Los Horcones; as a result of an amnesty, he served less than two. Zelaya joined the Liberal Party of Honduras, Partido Liberal de Honduras, in 1970 and became active a decade later, he was a deputy in the National Congress for three consecutive times between 1985 and 1998. He held many positions within the PLH and was Minister for Investment in charge of the Honduran Social Investment Fund in a previous PLH government. Under the administration of Zelaya the FHIS lost $40 million. Zelaya escaped prosecution. In the 2005 presidential primaries, his faction was called Movimiento Esperanza Liberal, he received 52% of the 289,300 Liberal votes, vs. 17% for Jaime Rosenthal Oliva and 12% for Gabriela Núñez, the candidate of the Nueva Mayoría faction.
During Zelaya's time in office Honduras became a member of ALBA, an international cooperation organization based on the idea of social and economic integration between the countries of Latin America and the Caribbean. It marked his turning to a left-of-center politics, the first such case of right to left policy switch as he had been elected in on a conservative platform. Political opponents business elites, opposed his foreign policy, including his alliance with Hugo Chávez in Venezuela, friendship with Cuba's Raúl Castro. In spite of a number of economic problems, there were a number of significant achievements under Zelaya's presidency. Under his government, free education for all children was introduced, subsidies to small farmers were provided, bank interest rates were reduced, the minimum wage was increased by 80%, school meals were guaranteed for more than 1.6 million children from poor families, domestic employees were integrated into the social security system, poverty was reduced by 10% during two years of government, direct state help was provided for 200,000 families in extreme poverty, with free electricity supplied to those Hondurans most in need.
On 22 July 2008, Zelaya sought to incorporate Honduras into ALBA, an international cooperation organization based on the idea of social and economic integration in Latin America and the Caribbean. Zelaya said that the main media outlets in Honduras, owned by wealthy conservatives, were biased against him and did not cover what his government was doing: "No one publishes anything about me.... What prevails here is censorship of my government by the mass media."On 24 May 2007, Zelaya ordered ten two-hour cadenas on all television and radio stations, "to counteract the misinformation of the news media". The move, while legal, was fiercely criticized by the country's main journalists' union, Zelaya was dubbed "authoritarian" by his opposition; the broadcasts were scaled back to a one-hour program on the government's plans to expand telephone service, a half-hour on new electrical power plants and a half-hour about government revenues. An unknown gunman in 2007 murdered a journalist who criticized Zelaya.

Red is the color at the end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of 625–740 nanometres, it is a primary color in the RGB color model and the CMYK color model, is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, vary in shade from the pale red pink to the dark red burgundy; the red sky at sunset results from Rayleigh scattering, while the red color of the Grand Canyon and other geological features is caused by hematite or red ochre, both forms of iron oxide. Iron oxide gives the red color to the planet Mars; the red colour of blood comes from protein hemoglobin, while ripe strawberries, red apples and reddish autumn leaves are colored by anthocyanins. Red pigment made from ochre was one of the first colors used in prehistoric art; the Ancient Egyptians and Mayans colored their faces red in ceremonies. It was an important color in China, where it was used to colour early pottery and the gates and walls of palaces.
In the Renaissance, the brilliant red costumes for the nobility and wealthy were dyed with kermes and cochineal. The 19th century brought the introduction of the first synthetic red dyes, which replaced the traditional dyes. Red became the color of revolution. Since red is the color of blood, it has been associated with sacrifice and courage. Modern surveys in Europe and the United States show red is the color most associated with heat, passion, anger and joy. In China and many other Asian countries it is the color of symbolizing happiness and good fortune. See below for shades of pink The human eye sees red when it looks at light with a wavelength between 625 and 740 nanometers, it is a primary color in the RGB color model and the light just past this range is called infrared, or below red, cannot be seen by human eyes, although it can be sensed as heat. In the language of optics, red is the color evoked by light that stimulates neither the S or the M cone cells of the retina, combined with a fading stimulation of the L cone cells.
Primates can distinguish the full range of the colors of the spectrum visible to humans, but many kinds of mammals, such as dogs and cattle, have dichromacy, which means they can see blues and yellows, but cannot distinguish red and green. Bulls, for instance, cannot see the red color of the cape of a bullfighter, but they are agitated by its movement.. One theory for why primates developed sensitivity to red is that it allowed ripe fruit to be distinguished from unripe fruit and inedible vegetation; this may have driven further adaptations by species taking advantage of this new ability, such as the emergence of red faces. Red light is used to help adapt night vision in low-light or night time, as the rod cells in the human eye are not sensitive to red. Red illumination was used as a safelight while working in a darkroom as it does not expose most photographic paper and some films. Today modern darkrooms use an amber safelight. On the color wheel long used by painters, in traditional color theory, red is one of the three primary colors, along with blue and yellow.
Painters in the Renaissance mixed red and blue to make violet: Cennino Cennini, in his 15th-century manual on painting, wrote, "If you want to make a lovely violet colour, take fine lac, ultramarine blue with a binder" he noted that it could be made by mixing blue indigo and red hematite. In modern color theory known as the RGB color model, red and blue are additive primary colors. Red and blue light combined together makes white light, these three colors, combined in different mixtures, can produce nearly any other color; this is the principle, used to make all of the colors on your computer screen and your television. For example, magenta on a computer screen is made by a similar formula to that used by Cennino Cennini in the Renaissance to make violet, but using additive colors and light instead of pigment: it is created by combining red and blue light at equal intensity on a black screen. Violet is made on a computer screen in a similar way, but with a greater amount of blue light and less red light.
So that the maximum number of colors can be reproduced on your computer screen, each color has been given a code number, or sRGB, which tells your computer the intensity of the red and blue components of that color. The intensity of each component is measured on a scale of zero to 255, which means the complete list includes 16,777,216 distinct colors and shades; the sRGB number of pure red, for example, is 255, 00, 00, which means the red component is at its maximum intensity, there is no green or blue. The sRGB number for crimson is 220, 20, 60, which means that the red is less intense and therefore darker, there is some green, which leans it toward orange; as a ray of white sunlight travels through the atmosphere to the eye, some of the colors are scattered out of the beam by air molecules and airborne particles due to Rayleigh scattering, changing the final color of the beam, seen. Colors with a shorter wavelength, such as blue and green, scatter more and are removed from the light that reaches the eye.

National Coalition Party (El Salvador)
The National Coalition Party is a nationalist political party in El Salvador. Until 2011 it was known as the National Conciliation Party, it was the most powerful political party in the country during the 1960s and 1970s, was associated with the Salvadoran military. Julio Adalberto Rivera Carballo, a candidate of the National Conciliation Party, was elected president in 1962, the next three presidents were from the party. After the 1979 coup the party continued to exist. Today, it is considered minor as compared with the two major organizations, ARENA and the FMLN. At the legislative elections, held on 16 March 2003, the party won 13.0% of the popular vote and 16 out of 84 seats in the Legislative Assembly. Its candidate in the presidential election of 21 March 2004, José Rafael Machuca Zelaya, won 2.7%. In the 12 March 2006 legislative election, the party won 11.0% of the popular vote and 10 out of 84 seats, a major decline in representation, but the party is still the third largest political party in El Salvador.
At the January 18, 2009 legislative elections the party won 11 seats. With no party holding a majority, it can be seen as holding the balance of power. However, it sides with the conservative ARENA party. While the party was technically to be disbanded after the 2004 election, in which its candidate did not gather the necessary 3% of the vote, it was allowed to hold on to its registration by decree; the party was de facto re-established, registering with the Supreme Electoral Tribunal as the National Coalition in September 2011. After one year, it added the word'Partido' to its full name, which allowed it to again use the traditional acronym PCN. Since 2015, the party has 20 out of 262 mayorship offices.

A political spectrum is a system of classifying different political positions upon one or more geometric axes that represent independent political dimensions. Most long-standing spectra include a left wing, which referred to seating arrangements in the French parliament after the Revolution. On a left–right spectrum and socialism are regarded internationally as being on the left, Liberalism can mean different things in different contexts: sometimes on the left; those with an intermediate outlook are sometimes classified as centrists. That said and neoliberals are called centrists too. Politics that rejects the conventional left–right spectrum is known as syncretic politics, though the label tends to mischaracterize positions that have a logical location on a two-axis spectrum because they seem randomly brought together on a one-axis left-right spectrum. Political scientists have noted that a single left–right axis is insufficient for describing the existing variation in political beliefs and include other axes.
Though the descriptive words at polar opposites may vary in popular biaxial spectra the axes are split between socio-cultural issues and economic issues, each scaling from some form of individualism to some form of communitarianism. The terms right and left refer to political affiliations originating early in the French Revolutionary era of 1789–1799 and referred to the seating arrangements in the various legislative bodies of France; as seen from the Speaker's seat at the front of the Assembly, the aristocracy sat on the right and the commoners sat on the left, hence the terms right-wing politics and left-wing politics. The defining point on the ideological spectrum was the Ancien Régime. "The Right" thus implied support for aristocratic or royal interests and the church, while "The Left" implied support for republicanism and civil liberties. Because the political franchise at the start of the revolution was narrow, the original "Left" represented the interests of the bourgeoisie, the rising capitalist class.
Support for laissez-faire commerce and free markets were expressed by politicians sitting on the left because these represented policies favorable to capitalists rather than to the aristocracy, but outside parliamentary politics these views are characterized as being on the Right. The reason for this apparent contradiction lies in the fact that those "to the left" of the parliamentary left, outside official parliamentary structures represent much of the working class, poor peasantry and the unemployed, their political interests in the French Revolution lay with opposition to the aristocracy and so they found themselves allied with the early capitalists. However, this did not mean that their economic interests lay with the laissez-faire policies of those representing them politically; as capitalist economies developed, the aristocracy became less relevant and were replaced by capitalist representatives. The size of the working class increased as capitalism expanded and began to find expression through trade unionist, socialist and communist politics rather than being confined to the capitalist policies expressed by the original "left".
This evolution has pulled parliamentary politicians away from laissez-faire economic policies, although this has happened to different degrees in different countries those with a history of issues with more authoritarian-left countries, such as the Soviet Union or China under Mao Zedong. Thus the word "Left" in American political parlance may refer to "liberalism" and be identified with the Democratic Party, whereas in a country such as France these positions would be regarded as more right-wing, or centrist overall, "left" is more to refer to "socialist" or "social-democratic" positions rather than "liberal" ones. For a century, social scientists have considered the problem of how best to describe political variation. In 1950, Leonard W. Ferguson analyzed political values using ten scales measuring attitudes toward: birth control, capital punishment, communism, law, theism, treatment of criminals and war. Submitting the results to factor analysis, he was able to identify three factors, which he named religionism and nationalism.
He defined religionism as belief in God and negative attitudes toward birth control. This system was derived empirically, as rather than devising a political model on purely theoretical grounds and testing it, Ferguson's research was exploratory; as a result of this method, care must be taken in the interpretation of Ferguson's three factors, as factor analysis will output an abstract factor whether an objectively real factor exists or not. Although replication of the nationalism factor was inconsistent, the finding of religionism and humanitarianism had a number of replications by Ferguson and others. Shortly afterward, Hans Eysenck began researching political attitudes in Great Britain, he believed that there was something similar about the National Socialists on the one hand and the communists on the other, despite their opposite positions on the left–right axis. As Hans Eysenck described in his 1956 book Sense and
Blue is one of the three primary colours of pigments in painting and traditional colour theory, as well as in the RGB colour model. It lies between green on the spectrum of visible light; the eye perceives blue when observing light with a dominant wavelength between 450 and 495 nanometres. Most blues contain a slight mixture of other colours; the clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called. Distant objects appear. Blue has been an important colour in decoration since ancient times; the semi-precious stone lapis lazuli was used in ancient Egypt for jewellery and ornament and in the Renaissance, to make the pigment ultramarine, the most expensive of all pigments. In the eighth century Chinese artists used cobalt blue to white porcelain. In the Middle Ages, European artists used it in the windows of Cathedrals. Europeans wore clothing coloured with the vegetable dye woad until it was replaced by the finer indigo from America.
In the 19th century, synthetic blue dyes and pigments replaced mineral pigments and synthetic dyes. Dark blue became a common colour for military uniforms and in the late 20th century, for business suits; because blue has been associated with harmony, it was chosen as the colour of the flags of the United Nations and the European Union. Surveys in the US and Europe show that blue is the colour most associated with harmony, confidence, infinity, the imagination and sometimes with sadness. In US and European public opinion polls it is the most popular colour, chosen by half of both men and women as their favourite colour; the same surveys showed that blue was the colour most associated with the masculine, just ahead of black, was the colour most associated with intelligence, knowledge and concentration. Blue is the colour of light between green on the visible spectrum. Hues of blue include ultramarine, closer to violet. Blue varies in shade or tint. Darker shades of blue include ultramarine, cobalt blue, navy blue, Prussian blue.
Blue pigments were made from minerals such as lapis lazuli and azurite, blue dyes were made from plants. Today most blue dyes are made by a chemical process; the modern English word blue comes from Middle English bleu or blewe, from the Old French bleu, a word of Germanic origin, related to the Old High German word blao. In heraldry, the word azure is used for blue. In Russian and some other languages, there is no single word for blue, but rather different words for light blue and dark blue. See Colour term. Several languages, including Japanese, Thai and Lakota Sioux, use the same word to describe blue and green. For example, in Vietnamese the colour of both tree leaves and the sky is xanh. In Japanese, the word for blue is used for colours that English speakers would refer to as green, such as the colour of a traffic signal meaning "go". Linguistic research indicates. Colour names developed individually in natural languages beginning with black and white, adding red, only much – as the last main category of colour accepted in a language – adding the colour blue when blue pigments could be manufactured reliably in the culture using that language.
Human eyes perceive blue when observing light which has a dominant wavelength of 450–495 nanometres. Blues with a higher frequency and thus a shorter wavelength look more violet, while those with a lower frequency and a longer wavelength appear more green. Pure blue, in the middle, has a wavelength of 470 nanometres. Isaac Newton included blue as one of the seven colours in his first description the visible spectrum, He chose seven colours because, the number of notes in the musical scale, which he believed was related to the optical spectrum, he included indigo, the hue between blue and violet, as one of the separate colours, though today it is considered a hue of blue. In painting and traditional colour theory, blue is one of the three primary colours of pigments, which can be mixed to form a wide gamut of colours. Red and blue mixed together form violet and yellow together form green. Mixing all three primary colours together produces a dark grey. From the Renaissance onwards, painters used this system to create their colours.
The RYB model was used for colour printing by Jacob Christoph Le Blon as early as 1725. Printers discovered that more accurate colours could be created by using combinations of magenta, cyan and black ink, put onto separate inked plates and overlaid one at a time onto paper; this method could produce all the colours in the spectrum with reasonable accuracy. In the 19th century the Scottish physicist James Clerk Maxwell found a new way of explaining colours, by the wa
