Green
Green is the color between blue and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of roughly 495570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and blue, or yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy.
Color
Color (American English) or colour (Commonwealth English) is the characteristic of human visual perception described through color "categories", with names such as red, blue, yellow, green, orange, or purple. This perception of color derives from the stimulation of cone cells in the human eye by electromagnetic radiation in the spectrum of light. Color categories and physical specifications of color are associated with objects through the wavelength of the light that is reflected from them. This reflection is governed by the object's physical properties such as light absorption, emission spectra, etc.
Color vision
Color vision is the ability of an organism or machine to distinguish objects based on the wavelengths (or frequencies) of the light they reflect, emit, or transmit. Colors can be measured and quantified in various ways; indeed, a person's perception of colors is a subjective process whereby the brain responds to the stimuli that are produced when incoming light reacts with the several types of cone cells in the eye. In essence, different people see the same illuminated object or light source in different ways. Isaac Newton discovered that white light, after being split into its component colours when passed through a dispersive prism, could, by passing them through a different prism, be recombined to make white light.
Blue–green distinction in language
Many languages do not distinguish between what in English are described as "blue" and "green" and instead use a cover term spanning both. To describe this English lexical gap, linguists use the portmanteau word "grue", from "green" and "blue", which the philosopher Nelson Goodman coined in his 1955 "Fact, Fiction, and Forecast" to illustrate the "new riddle of induction". The exact definition of "blue" and "green" may be complicated by the speakers not primarily distinguishing the hue, but using terms that describe other color components such as saturation and luminosity, or other properties of the object being described.
Color blindness
Color blindness, also known as color vision deficiency, is the decreased ability to see color or differences in color. Color blindness can make some educational activities difficult. Buying fruit, picking clothing, and reading traffic lights can be more challenging, for example. Problems, however, are generally minor and most people adapt. People with total color blindness, however, may also have decreased visual acuity and be uncomfortable in bright environments. The most common cause of color blindness is an inherited fault in the development of one or more of the three sets of color sensing cones in the eye.
Shades of green
Varieties of the color green may differ in hue, chroma (also called saturation or intensity) or lightness (or value, tone, or brightness), or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a green or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below. Green is common in nature, especially in plants. Many plants are green mainly because of a complex chemical known as chlorophyll which is involved in photosynthesis. Many shades of green have been named after plants or are related to plants.
On Vision and Colors
On Vision and Colors () is a treatise by Arthur Schopenhauer that was published in May 1816 when the author was 28 years old. Schopenhauer had extensive discussions with Johann Wolfgang von Goethe about the poet's "Theory of Colours" of 1810, in the months around the turn of the years 1813 and 1814, and basically shared Goethe's views. Schopenhauer tried to demonstrate physiologically that color is "specially modified activity of the retina." The initial basis for Schopenhauer's color theory comes from Goethe's chapter on physiological colors, which discusses three principal pairs of contrasting colors: red/green, orange/blue, and yellow/violet.

Anaglyph 3D
Anaglyph 3D is the name given to the stereoscopic 3D effect achieved by means of encoding each eye's image using filters of different (usually chromatically opposite) colors, typically red and cyan. Anaglyph 3D images contain two differently filtered colored images, one for each eye. When viewed through the "color-coded" "anaglyph glasses", each of the two images reaches the eye it's intended for, revealing an integrated stereoscopic image. The visual cortex of the brain fuses this into the perception of a three-dimensional scene or composition. Anaglyph images have seen a recent resurgence due to the presentation of images and video on the Web, Blu-ray Discs, CDs, and even in print.
Shades of cyan
This article is about notable tints and shades of the color cyan, a greenish blue. Cyan is one of the subtractive primary colors- cyan, magenta, and yellow. The first recorded use of "cyan blue" ("cyan blue" was the name used for the color "cyan" in the 19th century) as a color name in English was in 1879. 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.
Cyan
Cyan ( or ) is a greenish-blue color. It is evoked by light with a predominant wavelength of between 490520 nm, between the wavelengths of blue and green. In the subtractive color system, or CMYK (subtractive), which can be overlaid to produce all colors in paint and color printing, cyan is one of the primary colors, along with magenta, yellow, and black. In the additive color system, or RGB (additive) 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 light.
Complementary colors
Complementary colors are pairs of colors which, when combined, cancel each other out. This means that when combined, they produce a gray-scale color like white or black. When placed next to each other, they create the strongest contrast for those particular two colors. Due to this striking color clash, the term opposite colors is often considered more appropriate than "complementary colors". Which pairs of colors are considered complementary depends on the color theory one uses:  On the traditional color wheel developed in the 18th century, used by Claude Monet and Vincent van Gogh and other painters, and still used by many artists today, the primary colors were considered to be red, yellow, and blue, and the primary–secondary complementary pairs are red–green (Christmas), blue-orange (Westwood), and yellow–purple (Mesa High).
Cyan Worlds
Cyan Inc., also known as Cyan Worlds Inc., is an American video game developer, founded as Cyan Productions by brothers Rand and Robyn Miller in 1987, and best known as the creators of the "Myst" series. After "Myst" and its sequel "Riven" sold several million copies each, Cyan went on to create the massively multiplayer online adventure, "", which was cancelled and re-opened several times. After the departure of brother Robyn Miller from "Cyan, Inc.," a second company, "Cyan Worlds, Inc.," was started. Both companies are located in Mead, Washington, just outside Spokane. Cyan was founded in 1987 by brothers Rand and Robyn Miller, operating out of their parents' basement in their Spokane, Washington home.
CMYK color model
The CMYK color model (process color, four color) is a subtractive color model, used in color printing, and is also used to describe the printing process itself. CMYK refers to the four inks used in some color printing: cyan, magenta, yellow, and key (black). Although it varies by print house, press operator, press manufacturer, and press run, ink is typically applied in the order of the abbreviation. 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.
Myst
Myst is a graphic adventure puzzle video game designed by the brothers Robyn and Rand Miller. It was developed by Cyan, Inc., published by Brøderbund, and released on the Macintosh platform in 1993. The game puts the player in the role of the Stranger, who uses a special book to travel to the island of Myst. There, the player solves puzzles and travels to other worlds known as "Ages". Clues found in each of these Ages help to reveal the back-story of the game's characters. The game has several endings, depending on the course of action the player takes. "Myst" was a surprise hit, with critics lauding the ability of the game to immerse players in the fictional world.

Its been around since he middles ages as well, it was associated with merchants and bankers.
In the Middle Ages and Renaissance, green was the color commonly associated with merchants, bankers and the gentry, while red was reserved for the nobility.

Dipper well
A dipper well is a perpetual-flow sink often used in coffeehouses and ice cream shops to rinse utensils. Ice cream scoops and other food-preparation utensils can be placed under the continuous stream in order to remove allergens and protect against bacterial growth. Most dipper wells have a single spigot and can be adjusted for both hot and cold water use. As largely a commercial appliance, dipper well valves are typically kept at full flow during all serving hours. Dipper wells have also been used as key components in pharmacological experimentation. The dipper well has been criticized in the United States as wasteful since on average it pumps of water an hour and is normally left running continuously.
Scotland in the Middle Ages
Scotland in the Middle Ages concerns the history of Scotland from the departure of the Romans to the adoption of major aspects of the Renaissance in the early sixteenth century. From the fifth century northern Britain was divided into a series of petty kingdoms. Of these the four most important to emerge were the Picts, the Gaels of Dál Riata, the Britons of Strathclyde and the Anglian kingdom of Bernicia. After the arrival of the Vikings in the late eighth century, Scandinavian rulers and colonies were established along parts of the coasts and in the islands. In the ninth century the Scots and Picts combined under the House of Alpin to form a single Kingdom of Alba, with a Pictish base and dominated by Gaelic culture.
Musical instrument
A musical instrument is an instrument created or adapted to make musical sounds. In principle, any object that produces sound can be considered a musical instrument—it is through purpose that the object becomes a musical instrument. The history of musical instruments dates to the beginnings of human culture. Early musical instruments may have been used for ritual, such as a trumpet to signal success on the hunt, or a drum in a religious ceremony. Cultures eventually developed composition and performance of melodies for entertainment. Musical instruments evolved in step with changing applications.
History of banking
The history of banking began with the first prototype banks where the merchants of the world, who made grain loans to farmers and traders who carried goods between cities. This was around 2000 BC in Assyria and Sumeria. Later, in ancient Greece and during the Roman Empire, lenders based in temples made loans, while accepting deposits and performing the change of money. Archaeology from this period in ancient China and India also shows evidence of money lending activity. Many histories position the crucial historical development of a banking system to medieval and Renaissance Italy and particularly the affluent cities of Florence, Venice and Genoa.
Paris in the Middle Ages
In the 10th century, Paris was a provincial cathedral city of little political or economic significance, but under the kings of the Capetian dynasty who ruled France between 987 and 1328, it developed into an important commercial and religious center and the seat of the royal administration of the country. The Île de la Cité became the site of the royal palace and the new cathedral of Notre-Dame, begun in 1163. The Left Bank was occupied by important monasteries, including the Abbey of Saint-Germain-des-Prés and the Abbey of St Genevieve. In the late 12th century, the collection of colleges on the left bank became one of the leading universities in Europe.
Paris in the 18th century
Paris in the 18th century was the second-largest city in Europe, after London, with a population of about 600,000 persons. The century saw the construction of Place Vendôme, the Place de la Concorde, the Champs-Élysées, the church of Les Invalides, and the Panthéon, and the founding of the Louvre Museum. Paris witnessed the end of the reign of Louis XIV, was the center stage of the Enlightenment and the French Revolution, saw the first manned flight, and was the birthplace of high fashion and the modern restaurant. Louis XIV distrusted the Parisians; when he was young he had been forced to flee the city twice, and he did not forget it.
Strasbourg massacre
The Strasbourg massacre occurred on February 14, 1349, when several hundred Jews were publicly burnt to death, and the rest of them expelled from the city as part of the Black Death persecutions. It was one of the first and worst pogroms in pre-modern history. Starting in the spring of 1348, pogroms against Jews had occurred in European cities, starting in Toulon. By November of that year they spread via Savoy to German-speaking territories. In January 1349, burnings of Jews took place in Basel and Freiburg, and on 14 February the Jewish community in Strasbourg was destroyed. This event was heavily linked to a revolt by the guilds five days previous, the consequences of which were, the displacement of the master tradesmen, a reduction of the power of the patrician bourgeoisie, who had until then been ruling almost exclusively, and an increase in the power of the groups that were involved in the revolt.
