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 colours; 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 effect explains blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective.
Film stock is an analog medium that is used for recording motion pictures or animation. It is recorded on by a movie camera, developed, edited, and projected onto a screen using a movie projector. It is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast and resolution of the film. The emulsion will gradually darken if left exposed to light, but the process is too slow and incomplete to be of any practical use. Instead, a very short exposure to the image formed by a camera lens is used to produce only a very slight chemical change, proportional to the amount of light absorbed by each crystal. This creates an invisible latent image in the emulsion, which can be chemically developed into a visible photograph. In addition to visible light, all films are sensitive to X-rays and high-energy particles. Most are at least slightly sensitive to invisible ultraviolet (UV) light. Some special-purpose films are sensitive into the infrared (IR) region of the spectrum.
Magenta is a colour that is variously defined as purplish-red, reddish-purple or mauvish-crimson. On colour wheels of the RGB (additive) and CMY (subtractive) colour models, it is located exactly midway between red and blue. It is one of the four colours of ink used in colour printing by an inkjet printer, along with yellow, black, and cyan, to make all other colours. The tone of magenta used in printing is called "printer's magenta".
Chroma key compositing, or chroma keying, is a visual-effects and post-production technique for compositing (layering) two images or video streams together based on colour hues. The technique has been used in many fields to remove a background from the subject of a photo or video – particularly the newscasting, motion picture, and video game industries. A colour range in the foreground footage is made transparent, allowing separately filmed background footage or a static image to be inserted into the scene. The chroma keying technique is commonly used in video production and post-production. This technique is also referred to as colour keying, colour-separation overlay, or by various terms for specific colour-related variants such as green screen, blue screen and magic pink; chroma keying can be done with backgrounds of any colour that are uniform and distinct, but green and blue backgrounds are more commonly used because they differ most distinctly in hue from human skin colours. No part of the subject being filmed or photographed may duplicate the colour used as the backing, otherwise, the part may be erroneously identified as part of the backing.
Orange is the colour between yellow and red on the spectrum of visible light. Human eyes perceive orange when observing light with a dominant wavelength between roughly 585 and 620 nanometres. In painting and traditional colour theory, it is a secondary colour of pigments, created by mixing yellow and red. It is named after the fruit of the same name.
The International Commission on Illumination is the international authority on light, illumination, colour, and colour spaces. It was established in 1913 as a successor to the Commission Internationale de Photométrie, which was founded in 1900, and is today based in Vienna, Austria. The President from 2019 is Dr Peter Blattner from Switzerland.
Living Colour is an American rock band from New York City, formed in 1984. The band currently consists of guitarist Vernon Reid, lead vocalist Corey Glover, drummer Will Calhoun and bassist Doug Wimbish, who replaced Muzz Skillings in 1992. Stylistically, their music is a creative fusion influenced by heavy metal, funk, jazz, hip hop, punk, and alternative rock. The band's lyrics range from the personal to the political, including social commentary on racism in America.
Chromatophores are cells that produce color, of which many types are pigment-containing cells, or groups of cells, found in a wide range of animals including amphibians, fish, reptiles, crustaceans and cephalopods. Mammals and birds, in contrast, have a class of cells called melanocytes for coloration.
Photographic paper is a paper coated with a light-sensitive chemical formula, like photographic film, used for making photographic prints. When photographic paper is exposed to light, it captures a latent image that is then developed to form a visible image; with most papers the image density from exposure can be sufficient to not require further development, aside from fixing and clearing, though latent exposure is also usually present. The light-sensitive layer of the paper is called the emulsion. The most common chemistry was based on Silver halide but other alternatives have also been used.
Sorry! is a board game that is based on the ancient Indian cross and circle game Pachisi. Players move their three or four pieces around the board, attempting to get all of their pieces "home" before any other player. Originally manufactured by W.H. Storey & Co in England and now by Hasbro, Sorry! is marketed for two to four players, ages 6 and up. The game title comes from the many ways in which a player can negate the progress of another, while issuing an apologetic "Sorry!"
The spore print is the powdery deposit obtained by allowing spores of a fungal fruit body to fall onto a surface underneath. It is an important diagnostic character in most handbooks for identifying mushrooms. It shows the color of the mushroom spores if viewed en masse.
Tincture is the limited palette of colours and patterns used in heraldry. The need to define, depict, and correctly blazon the various tinctures is one of the most important aspects of heraldic art and design.
Trooping the Colour is a ceremony performed by regiments of the British and Commonwealth armies. It has been a tradition of British infantry regiments since the 17th century, although its roots go back much earlier. On the battlefield, a regiment's colours, or flags, were used as rallying points. Consequently, regiments would have their ensigns slowly march with their colours between the ranks to enable soldiers to recognise their regiments' colours.
The term "person of color" is primarily used to describe any person who is not considered "white". In its current meaning, the term originated in, and is primarily associated with, the United States; however since the 2010s it has been adopted elsewhere in the Anglosphere, including relatively limited usage in the United Kingdom, Canada, Australia, Ireland, South Africa, and Singapore.
In military organizations, the practice of carrying colours, standards or guidons, both to act as a rallying point for troops and to mark the location of the commander, is thought to have originated in Ancient Egypt some 5,000 years ago. The Roman Empire also made battle standards a part of their vast armies. It was formalized in the armies of Europe in the High Middle Ages, with standards being emblazoned with the commander's coat of arms.
The Saint is a British ITC mystery spy thriller television series that aired in the United Kingdom on ITV between 1962 and 1969. It was based on the literary character Simon Templar created by Leslie Charteris in the 1920s and featured in many novels over the years. In the tv series Templar is played by Roger Moore. Templar helps those whom conventional agencies are powerless or unwilling to protect, often using methods that skirt the law. Chief Inspector Claud Eustace Teal is his nominal nemesis who considers Templar a common criminal, but often grudgingly tolerates his actions for the greater good.
Dufaycolor is an early British additive colour photographic film process, introduced for motion picture use in 1932 and for still photography in 1935. It was derived from Louis Dufay's Dioptichrome plates, a glass-based product for colour still photography, introduced in France in 1909. Both Dioptichrome and Dufaycolor worked on the same principles as the Autochrome process, but achieved their results using a layer of tiny colour filter elements arrayed in a regular geometric pattern, unlike Autochrome's random array of coloured starch grains. The manufacture of Dufaycolor film ended in the late 1950s.
The kelvin is the base unit of temperature in the International System of Units (SI), having the unit symbol K. It is named after the Belfast-born Glasgow University engineer and physicist William Thomson, 1st Baron Kelvin (1824–1907).
Abalos Undae is a dune field on Mars in the periphery of Planum Boreum, the Martian North pole. It is one of the officially named northern circumpolar dune fields, along with Olympia, Hyperboreae, and Siton Undae, and also one of the densest of the region. Its northernmost boundary is located in the southwest channel that separates the Abalos Colles formation from the main polar ice cap, and from there the dune field extends southwest all the way to the lowlands of Vastitas Borealis.
