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.
Chloroplast
Chloroplasts are organelles, specialized compartments, in plant and algal cells. Their discovery inside plant cells is usually credited to Julius von Sachs (1832–1897), an influential botanist and author of standard botanical textbooks – sometimes called "The Father of Plant Physiology". The main role of chloroplasts is to conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight and converts it and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water. They then use the ATP and NADPH to make organic molecules from carbon dioxide in a process known as the Calvin cycle.
Chlorophyll
Chlorophyll (also chlorophyl) is any of several related green pigments found in cyanobacteria and the chloroplasts of algae and plants. Its name is derived from the Greek words χλωρός, "chloros" ("green") and φύλλον, "phyllon" ("leaf"). Chlorophyll is essential in photosynthesis, allowing plants to absorb energy from light. Chlorophylls absorb light most strongly in the blue portion of the electromagnetic spectrum as well as the red portion. Conversely, it is a poor absorber of green and near-green portions of the spectrum, which it reflects, producing the green color of chlorophyll-containing tissues.
Photosynthesis
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities (energy transformation). This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name "photosynthesis", from the Greek φῶς, "phōs", "light", and σύνθεσις, "synthesis", "putting together". In most cases, oxygen is also released as a waste product. Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs.
SeaWiFS
SeaWIFS (Sea-Viewing Wide Field-of-View Sensor) was a satellite-borne sensor designed to collect global ocean biological data. Active from September 1997 to December 2010, its primary mission was to quantify chlorophyll produced by marine phytoplankton (microscopic plants). SeaWiFS was the only scientific instrument on GeoEye's OrbView-2 (AKA SeaStar) satellite, and was a follow-on experiment to the Coastal Zone Color Scanner on Nimbus 7. Launched August 1, 1997 on an Orbital Sciences Pegasus small air-launched rocket, SeaWiFS began scientific operations on September 18, 1997 and stopped collecting data on December 11, 2010, far exceeding its designed operating period of 5 years.
List of Green Lanterns
The Green Lantern Corps that appear in fictional stories published by DC Comics has at least 7200 members, two per sector (originally 3600 with one per sector), in addition to assorted other members who fulfill roles other than patrolling. Although seven characters—Alan Scott, Hal Jordan, Guy Gardner, John Stewart, Simon Baz, Kyle Rayner, and Jessica Cruz—are primarily associated with the name, a number of other members of the Corps have appeared in DC's comics. These seven characters are most closely associated with the "Green Lantern" name, and have been the title characters of "Green Lantern" comics.
Chlorophyll a
Chlorophyll "a" is a specific form of chlorophyll used in oxygenic photosynthesis. It absorbs most energy from wavelengths of violet-blue and orange-red light. It also reflects green/yellow light, and as such contributes to the observed green color of most plants. This photosynthetic pigment is essential for photosynthesis in eukaryotes, cyanobacteria and prochlorophytes because of its role as primary electron donor in the electron transport chain. Chlorophyll "a" also transfers resonance energy in the antenna complex, ending in the reaction center where specific chlorophylls P680 and P700 are located.

Red
Red is the colour at the end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and 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.
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.
Black
Black is the darkest color, the result of the absence or complete absorption of visible light. It is an achromatic color, literally a color without hue, like white (its opposite) and gray. It is often used symbolically or figuratively to represent darkness, while white represents light. Black ink is the most common color used for printing books, newspapers and documents, because it has the highest contrast with white paper and is the easiest to read. For the same reason, black text on a white screen is the most common format used on computer screens. In color printing it is used along with the subtractive primaries cyan, yellow, and magenta, in order to help produce the darkest shades.
Financial history of the Dutch Republic
The financial history of the Dutch Republic involves the interrelated development of financial institutions in the Dutch Republic. The rapid economic development of the country after the Dutch Revolt in the years 1585 - 1620 accompanied by an equally rapid accumulation of a large fund of savings, created the need to invest those savings profitably. The Dutch financial sector, both in its public and private components, came to provide a wide range of modern investment products beside the possibility of (re-)investment in trade and industry, and in infrastructure projects. Such products were the public bonds, floated by the Dutch governments on a national, provincial, and municipal level; acceptance credit and commission trade; marine and other insurance products; and shares of publicly traded companies like the Dutch East India Company (VOC), and their derivatives.
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.
History of Lisbon
The history of Lisbon, the capital city of Portugal, revolves around its strategic geographical position at the mouth of the Tagus, the longest river in the Iberian Peninsula. Its spacious and sheltered natural harbour made the city historically an important seaport for trade between the Mediterranean Sea and northern Europe. Lisbon has long enjoyed the commercial advantages of its proximity to southern and extreme western Europe, as well as to sub-Saharan Africa and the Americas, and today its waterfront is lined with miles of docks, wharfs, and drydock facilities that accommodate the largest oil tankers.

No but it is part of the RGB color model.
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.

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 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. Before the electronic age, the RGB color model already had a solid theory behind it, based in 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 R, G, and B levels vary from manufacturer to manufacturer, or even in the same device over time.
Color space
A color space is a specific organization of colors. In combination with physical device profiling, it allows for reproducible representations of color, in both analog and digital representations. A color space may be arbitrary, with particular colors assigned to a set of physical color swatches and corresponding assigned names or numbers such as with the Pantone collection, or structured mathematically, as with NCS System, Adobe RGB or sRGB. A color model is an abstract mathematical model describing the way colors can be represented as tuples of numbers (e.g. triples in RGB or quadruples in CMYK); however, a color model with no associated mapping function to an absolute color space is a more or less arbitrary color system with no connection to any globally understood system of color interpretation.
RGB color space
An RGB color space is any additive color space based on the RGB color model. A particular RGB color space is defined by the three chromaticities of the red, green, and blue additive primaries, and can produce any chromaticity that is the triangle defined by those primary colors. The complete specification of an RGB color space also requires a white point chromaticity and a gamma correction curve. As of 2007, sRGB is by far the most commonly used RGB color space. RGB is an abbreviation for red–green–blue. An RGB color can be understood by thinking of it as all possible colors that can be made from three colored lights for red, green, and blue.
List of color spaces and their uses
This is a list of color spaces and their uses. There are five major models, that sub-divide into others, which are: CIE, RGB, YUV, HSL/HSV, and CMYK. The first attempt to produce a color space based on measurements of human color perception and the basis for almost all other color spaces. A modification of "CIE 1931 XYZ" to display color differences more conveniently. The CIELUV space is especially useful for additive mixtures of lights, due to its linear addition properties. The intention of CIELAB (or L*a*b* or Lab) is to produce a color space that is more perceptually linear than other color spaces.
YCoCg
The YCoCg color model is the color space formed from a simple transformation of an associated RGB color space into a "luma" value (denoted as Y) and two "chroma" values called "chrominance green" (Cg) and "chrominance orange" (Co). It is supported in video and image compression designs such as H.264/MPEG-4 AVC, HEVC, JPEG XR, and Dirac, since it is simple to compute, has good transform coding gain, and can be losslessly converted to and from RGB with fewer bits than are needed with other color models. Advantages the YCoCg color model has over the YCbCr color model are simpler and faster computation, better decorrelation of the color planes to improve compression performance, and exactly lossless invertibility.
CIE 1931 color space
The CIE 1931 color spaces were the first defined quantitative links between distributions of wavelengths in the electromagnetic visible spectrum, and physiological perceived colors in human color vision. The mathematical relationships that define these color spaces are essential tools for color management, important when dealing with color inks, illuminated displays, and recording devices such as digital cameras. The CIE 1931 RGB color space and CIE 1931 XYZ color space were created by the International Commission on Illumination (CIE) in 1931. They resulted from a series of experiments done in the late 1920s by William David Wright and John Guild.
Magenta
Magenta () is a color that is variously defined as purplish-red, reddish-purple, purplish-pink, or mauvish-crimson. On computer screens, it is made by mixing equal amounts of blue and red. On color wheels of the RGB (additive) and CMY (subtractive) color models, it is located midway between red and blue. It is the complementary color of green. It is one of the four colors of ink used in color printing and by an inkjet printer, along with cyan, yellow, and black, to make all the other colors. The tone of magenta used in printing is called "printer's magenta". Magenta took its name from an aniline dye made and patented in 1859 by the French chemist François-Emmanuel Verguin, who originally called it "fuchsine".

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.
Dominant wavelength
In color science, the dominant wavelength (and the corresponding complementary wavelength) are ways of characterizing any light mixture in terms of the monochromatic spectral light that evokes an identical (and the corresponding opposite) perception of hue. For a given physical light mixture, the dominant and complementary wavelengths are not entirely fixed, but vary according to the illuminating light's precise color, called the white point, due to the color constancy of vision. On the CIE color coordinate space , a straight line drawn between the point for a given color and the point for the color of the illuminant can be extrapolated out so that it intersects the perimeter of the space in two points.
Yellow
Yellow is the color between green and orange on the spectrum of visible light. It is evoked by light with a dominant wavelength of roughly 570590 nm. It is a primary color in subtractive color systems, used in painting or color printing. In the RGB color model, used to create colors on television and computer screens, yellow is a secondary color made by combining red and green at equal intensity. Carotenoids give the characteristic yellow color to autumn leaves, corn, canaries, daffodils, and lemons, as well as egg yolks, buttercups, and bananas. They absorb light energy and protect plants from photodamage.
Ultraviolet
Ultraviolet (UV) is an electromagnetic radiation with a wavelength from 10 nm to 400 nm, shorter than that of visible light but longer than X-rays. UV radiation constitutes about 10% of the total light output of the Sun, and is thus present in sunlight. It is also produced by electric arcs and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. Although it's not considered an ionizing radiation because its photons lack the energy to ionize atoms, long-wavelength ultraviolet radiation can cause chemical reactions and causes many substances to glow or fluoresce. Consequently, the chemical and biological effects of UV are greater than simple heating effects, and many practical applications of UV radiation derive from its interactions with organic molecules.
Extreme ultraviolet lithography
Extreme ultraviolet lithography (also known as "EUV" or "EUVL") is a next-generation lithography technology using an extreme ultraviolet (EUV) wavelength, currently expected to be 13.5 nm. EUV is currently being developed for high volume use by 2020. The tool consists of a laser-driven tin (Sn) plasma light source, reflective optics comprising multilayer mirrors, contained within a hydrogen gas ambient. The hydrogen is used for keeping the EUV collector mirror in the source free of Sn deposition. EUVL is a significant departure from the deep ultraviolet lithography standard. All matter absorbs EUV radiation.
Laser pointer
A laser pointer or laser pen is a small handheld device with a power source (usually a battery) and a laser diode emitting a very narrow coherent low-powered laser beam of visible light, intended to be used to highlight something of interest by illuminating it with a small bright spot of colored light. Power is restricted in most jurisdictions not to exceed 5 mW. The small width of the beam and low power of typical laser pointers make the beam itself invisible in a reasonably clean atmosphere, only showing a point of light when striking an opaque surface. Some higher-powered laser pointers project a visible beam via scattering from dust particles or water droplets along the beam path.
