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.
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.
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.
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).
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.

Color psychology
Color psychology is the study of hues as a determinant of human behavior. Color influences perceptions that are not obvious, such as the taste of food. Colours can also enhance the effectiveness of placebos. For example, red or orange pills are generally used as stimulants. Colour can indeed influence a person; however, it is important to remember that these effects differ between people. Factors such as gender, age, and culture can influence how an individual perceives color. For instance, heterosexual men tend to report that red outfits enhance female attractiveness, while heterosexual females deny any outfit color impacting that of men.
Glutinoglossum glutinosum
Glutinoglossum glutinosum, commonly known as the viscid black earth tongue or the glutinous earthtongue, is a species of fungus in the family Geoglossaceae (the earth tongues). Widely distributed in the Northern Hemisphere, it has been found in northern Africa, Asia, Europe, and North America. Although previously thought to exist in Australasia, collections made from these locations have since been referred to new species. "G. glutinosum" is a saprophytic species that grows on soil in moss or in grassy areas. The smooth, nearly black, club-shaped fruitbodies grow to heights ranging from . The head is up to long, and the stipes are sticky.
Glutinoglossum
Glutinoglossum is a genus of six species of earth-tongue fungi in the family Geoglossaceae. The widespread type species, "G. glutinosum", is commonly known as the "glutinous earth tongue". "G. heptaseptatum" is known only from the Czech Republic. Four additional species were described in 2015. The genus was circumscribed in 2013 to contain the type species "Glutinoglossum glutinosum" (formerly known as "Geoglossum glutinosum"), and a new species, "G. heptaseptatum", found in the Czech Republic. Molecular analysis showed that the two species form one of five well-defined clades in the Geoglossaceae.
Glutinoglossum heptaseptatum
Glutinoglossum heptaseptatum is a species of earth tongue fungus in the family Geoglossaceae. Described in 2013, it is indistinguishable from its close relative "G. glutinosum" without the use of a microscope, and is known for certain only from the Czech Republic. "Glutinoglossum heptaseptatum" was described in 2013 in a paper by mycologists V. P. Hustad, A. N. Miller, T. M. Dentinger and P. F. Cannon published in "Persoonia". It was placed in the newly described genus "Glutinoglossum". The genus was created for "G. heptaseptatum" and "G. glutinosum", which were found to comprise one of five distinct clades within the Geoglossaceae.
A Treatise of Human Nature
A Treatise of Human Nature (1738–40) is a book by Scottish philosopher David Hume, considered by many to be Hume's most important work and one of the most influential works in the history of philosophy. The "Treatise" is a classic statement of philosophical empiricism, skepticism, and naturalism. In the introduction Hume presents the idea of placing all science and philosophy on a novel foundation: namely, an empirical investigation into human nature. Impressed by Isaac Newton's achievements in the physical sciences, Hume sought to introduce the same experimental method of reasoning into the study of human psychology, with the aim of discovering the "extent and force of human understanding".
A Defense of Abortion
"A Defense of Abortion" is a moral philosophy paper by Judith Jarvis Thomson first published in 1971. Granting for the sake of argument that the fetus has a right to life, Thomson uses thought experiments to argue that the fetus's right to life does not trump the pregnant woman's right to control her own body and its life-support functions, and that induced abortion is therefore not morally impermissible. Her argument has many critics on both sides of the abortion debate, yet continues to receive defense. Thomson's imaginative examples and controversial conclusions have made "A Defense of Abortion" perhaps "the most widely reprinted essay in all of contemporary philosophy".
List of Mr. Men
The following is a list of Mr. Men, from the children's book series by Roger Hargreaves, also adapted into the children's television programme "The Mr. Men Show". Books one ("Mr. Tickle") to forty-three ("Mr. Cheerful") were written by Hargreaves, and the remainder by his son, Adam Hargreaves. Mr. Adventure is the 49th book in the "Mr. Men" series and the sixth one created by Adam Hargreaves. Mr. Adventure is yellow and bean shaped with a yellow nose. He wears red shoes and a blue cap, along with a green backpack. Mr. Bounce is the 22nd book in the "Mr. Men" series. Mr. Bounce is yellow and round and wears a pink hat.

Mars
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury. In English, Mars carries a name of the Roman god of war, and is often referred to as the "Red Planet" because the reddish iron oxide prevalent on its surface gives it a reddish appearance that is distinctive among the astronomical bodies visible to the naked eye. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth. The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons.
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.
Water on Mars
Almost all water on Mars today exists as ice, though it also exists in small quantities as vapor in the atmosphere and occasionally as low-volume liquid brines in shallow Martian soil. The only place where water ice is visible at the surface is at the north polar ice cap. Abundant water ice is also present beneath the permanent carbon dioxide ice cap at the Martian south pole and in the shallow subsurface at more temperate certain conditions. More than five million cubic kilometers of ice have been identified at or near the surface of modern Mars, enough to cover the whole planet to a depth of .
Timeline of Mars Science Laboratory
Timeline of Mars Science Laboratory is a timeline of the Mars Science Laboratory mission and its rover, "Curiosity". As of 09, 2018, "Curiosity" has been on the planet Mars for sols ( total days; ) since landing on August 6, 2012. "(See Current status.)" In April 2004, the United States National Aeronautics and Space Administration (NASA) called for scientific experiments and instruments proposals for the Mars Science Laboratory and rover mission. Launch was proposed for September 2009. By December 14, 2004, eight proposals were selected, including instruments from Russia and Spain. Testing of components also began in late 2004, including Aerojet's monopropellant engine with the ability to throttle from 15–100 percent thrust with a fixed propellant inlet pressure.
Modern Mars habitability
One of the central questions of modern Astrobiology is whether there is, or ever has been life on Mars. Mars probably had oceans in the past, and it definitely had lakes and a thicker atmosphere. Modern Mars has become cold, dry, and almost uninhabitable, yet, if life did ever arise on Mars, some hardy microbes and perhaps even multicellular life might survive there right through to the present. The only missions to search for life on Mars, the two Viking missions, returned results that were inconclusive . However the instruments were not designed to cope with the unusual conditions which Viking discovered on Mars, which may have confused the results of the experiments.
Iron
Iron is a chemical element with symbol Fe (from ) and atomic number 26. It is a metal in the first transition series. It is by mass the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. Its abundance in rocky planets like Earth is due to its abundant production by fusion in high-mass stars, where it is the last element to be produced with release of energy before the violent collapse of a supernova, which scatters the iron into space. Like the other group 8 elements, ruthenium and osmium, iron exists in a wide range of oxidation states, −2 to +7, although +2 and +3 are the most common.
Composition of Mars
The composition of Mars covers the branch of the geology of Mars that describes the make-up of the planet Mars. Also like Earth, Mars is a differentiated planet, meaning that it has a central core made up of metallic iron and nickel surrounded by a less dense, silicate mantle and crust. The planet's distinctive red colour is due to the oxidation of iron on its surface. Much of what we know about the elemental composition of Mars comes from orbiting spacecraft and landers. (See Exploration of Mars for list.) Most of these spacecraft carry spectrometers and other instruments to measure the surface composition of Mars by either remote sensing from orbit or "in situ" analyses on the surface.

Cream gene
The cream gene is responsible for a number of horse coat colors. Horses that have the cream gene in addition to a base coat color that is chestnut will become palomino if they are heterozygous, having one copy of the cream gene, or cremello, if they are homozygous. Similarly, horses with a bay base coat and the cream gene will be buckskin or perlino. A black base coat with the cream gene becomes the not-always-recognized smoky black or a smoky cream. Cream horses, even those with blue eyes, are not white horses. Dilution coloring is also not related to any of the white spotting patterns. The cream gene ("C") is an incomplete dominant allele with a distinct dosage effect.
Vermilion
Vermilion (sometimes spelled vermillion) is a brilliant red or scarlet pigment originally made from the powdered mineral cinnabar, and is also the name of the resulting color. It was widely used in the art and decoration of Ancient Rome, in the illuminated manuscripts of the Middle Ages, in the paintings of the Renaissance, as sindoor in India, and in the art and lacquerware of China. The word vermilion came from the Old French word "vermeillon", which was derived from "vermeil", from the Latin "vermiculus", the diminutive of the Latin word "vermis", or worm. It has the same origin as the English word vermin.
Prehistoric art
In the history of art, prehistoric art is all art produced in preliterate, prehistorical cultures beginning somewhere in very late geological history, and generally continuing until that culture either develops writing or other methods of record-keeping, or makes significant contact with another culture that has, and that makes some record of major historical events. At this point ancient art begins, for the older literate cultures. The end-date for what is covered by the term thus varies greatly between different parts of the world. The earliest human artifacts showing evidence of workmanship with an artistic purpose are the subject of some debate.
Champagne gene
The champagne gene is a simple dominant allele responsible for a number of rare horse coat colors. The most distinctive traits of horses with the champagne gene are the hazel eyes and pinkish, freckled skin, which are bright blue and bright pink at birth, respectively. The coat color is also affected: any hairs that would have been red are gold, and any hairs that would have been black are chocolate brown. If a horse inherits the champagne gene from either or both parents, a coat that would otherwise be chestnut is instead gold champagne, with bay corresponding to amber champagne, seal brown to sable champagne, and black to classic champagne.
Burney Relief
The Burney Relief (also known as the Queen of the Night relief) is a Mesopotamian terracotta plaque in high relief of the Isin-Larsa- or Old-Babylonian period, depicting a winged, nude, goddess-like figure with bird's talons, flanked by owls, and perched upon two lions. The relief is displayed in the British Museum in London, which has dated it between 1800 and 1750 BCE. It originates from southern Mesopotamia, but the exact find-site is unknown. Apart from its distinctive iconography, the piece is noted for its high relief and relatively large size, which suggest that it was used as a cult relief, making it a very rare survival from the period.
Prehistoric Rock-Art Site of the Côa Valley
The Prehistoric Rock-Art Site of the Côa Valley is an open-air Paleolithic archaeological site located in a region of northeastern Portugal, along the Portuguese-Spanish border. In the early 1990s rock engravings were discovered in Vila Nova de Foz Côa in the course of the construction of a dam in the valley of the Côa River. They include thousands of engraved rock drawings of horses, bovines and other animals, human and abstract figures, dated from 22,000 to 10,000 years B.C. The sites were reviewed by archaeologists and other specialists of UNESCO and other agencies. Public support grew for preservation of the archaeological artifacts and rock paintings both within Portugal and internationally, and in 1995 elections led to a change in government.
