Pre-attentive processing
Pre-attentive processing is the subconscious accumulation of information from the environment. All available information is pre-attentively processed. Then, the brain filters and processes what is important. Information that has the highest salience (a stimulus that stands out the most) or relevance to what a person is thinking about is selected for further and more complete analysis by conscious (attentive) processing. Understanding how pre-attentive processing works is useful in advertising, in education, and for prediction of cognitive ability. The reasons are unclear as to why certain information proceeds from pre-attentive to attentive processing while other information does not.
Inga dams
The Inga Dams are two hydroelectric dams connected to one of the largest waterfalls in the world, Inga Falls. They are located in the western Democratic Republic of the Congo and 140 miles southwest of Kinshasa. The Congo River drops . The Belgian colonial government was considering starting what it called "The Inga Scheme" on the eve of decolonization in 1959. Inga I was completed in 1972, and Inga II in 1982. The two hydroelectric dams, Inga I and Inga II, currently operate at a low output. Inga I has a total installed capacity of 351 MW and Inga II has 1424 MW. They were built under former president Mobutu Sese Seko as part of the Inga–Shaba project.
Spacecraft in Red Dwarf
The British television comedy Red Dwarf prominently features many different spaceships. The three principal ships are the "Red Dwarf" ship itself and its two main types of shuttlecraft, known as "Starbug" and "Blue Midget". Several other ships have appeared for one or two episodes only but are nonetheless important to "Red Dwarf" continuity. Several spaceships have been seen only in one episode, and a few ships have also been mentioned but not seen. The eponymous spaceship Red Dwarf is an enormous mining vessel owned by the Jupiter Mining Corporation. In the first episode "The End" (1988), and in some episodes early in the series chronologically set before the first episode, it is commanded by Captain Frank Hollister.
HMS Attentive (1804)
HMS "Attentive" was an "Archer"-class gun-brig of the Royal Navy, launched in 1804. she captured a small privateer and participated in some other captures in the Leeward Islands before returning to Britain, where she was broken up in 1812. "Attentive" was commissioned in November 1804 under Lieutenant John Harris. He sailed her for the leeward Islands in May 1805. In July and early August 1806, "Attentive" was part of a squadron that included and , and that was under the command of Commander Donald Campbell (acting), in "Lilly". Together, they supported General Francisco de Miranda in his quixotic and unsuccessful attempt to liberate the Viceroyalty of New Granada from Spain.
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.
HSL and HSV
HSL (Hue, Saturation, Lightness) and HSV (Hue, Saturation, Value) are two alternative representations of the RGB color model, designed in the 1970s by computer graphics researchers to more closely align with the way human vision perceives color-making attributes. In these models, colors of each hue are arranged in a radial slice, around a central axis of neutral colors which ranges from black at the bottom to white at the top. The HSV representation models the way paints of different colors mix together, with the saturation dimension resembling various shades of brightly colored paint, and the value dimension resembling the mixture of those paints with varying amounts of black or white paint.
List of Red vs. Blue characters
The following list describes each of the characters from the popular webseries "Red vs. Blue", originally created by Rooster Teeth Productions. Colonel Sarge is the leader of the Red Team on Blood Gulch. He is voiced by Matt Hullum, co-creator of the series, and first appeared at the end of . He has a Southern accent. Sarge is somewhat bloodthirsty, and the only Blood Gulch soldier on either team to actually be serious about war. It is mentioned that he has a military background and briefly joined the ODSTs. His preferred weapon is a shotgun, which he carries at all times. He has a passionate disgust for Grif, demonstrated by his repeated willingness to sacrifice Grif during combat missions as well as how all of his contingency plans are to kill Grif.

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.
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.
Blue
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 violet and green on the spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colors; azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called Tyndall scattering explains blue eyes.
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.
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.
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.
Delay line memory
Delay line memory is a form of computer memory, now obsolete, that was used on some of the earliest digital computers. Like many modern forms of electronic computer memory, delay line memory was a refreshable memory, but as opposed to modern random-access memory, delay line memory was sequential-access. Analog delay line technology had been used since the 1920s to delay the propagation of analog signals. When a delay line is used as a memory device, an amplifier and a pulse shaper are connected between the output of the delay line and the input. These devices recirculate the signals from the output back into the input, creating a loop that maintains the signal as long as power is applied.

Albert Henry Munsell
Albert Henry Munsell (January 6, 1858 – June 28, 1918) was an American painter, teacher of art, and the inventor of the Munsell color system. He was born in Boston, Massachusetts, attended and served on the faculty of Massachusetts Normal Art School, and died in nearby Brookline. As a painter, he was noted for seascapes and portraits. Munsell is famous for inventing the Munsell color system, an early attempt at creating an accurate system for numerically describing colors. He wrote three books about it: "A Color Notation" (1905), "Atlas of the Munsell Color System" (1915) and one published posthumously, "A Grammar of Color: Arrangements of Strathmore Papers in a Variety of Printed Color Combinations According to The Munsell Color System" (1921).
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.
Color term
A color term (or color name) is a word or phrase that refers to a specific color. The color term may refer to human perception of that color (which is affected by visual context) which is usually defined according to the Munsell color system, or to an underlying physical property (such as a specific wavelength of visible light). There are also numerical systems of color specification, referred to as color spaces. An important distinction must be established between color and shape, these two attributes usually are used in conjunction with one another when describing in language. For example, being labeled as alternative parts of speech terms color term and shape term.
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.
Munsell Color Company
The Munsell Color Company was founded by Albert H. Munsell in 1917 with two other stockholders, Arthur Allen and Ray Greenleaf. It was located at Boston, Massachusetts. This company was manufactured to carry on business by publishing books, selling color supplies for schools such as crayons, water colors, paper colors and school supply and to teach the principles of Munsell Color System. After the death of Albert H. Munsell, his son, Alexander Ector Orr Munsell, was convinced to take over the company and reorganized it, renamed as the Munsell Color Foundation. The Munsell Color Foundation moved to New York for educational purposes and established the Munsell Laboratory Research which was funded by the Munsell family.
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.
David MacAdam
Dr. David Lewis MacAdam (July 1, 1910 – March 9, 1998) was an American physicist and color scientist who made important contributions to color science and technology in the fields of colorimetry, color discrimination, color photography and television, and color order. (1)  MacAdam grew up in Upper Darby outside of Philadelphia, graduating from Upper Darby High School in 1928, attended Lehigh University, and in 1936 received a PhD in physics from MIT. Under Prof. Arthur C. Hardy, he originated the first course in color measurement and assisted Hardy in the preparation of “Handbook of Colorimetry,” published in 1936.
