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. Computer web color greens Green The color defined as ''green'' in the RGB color model is the brightest green that can be reproduced on a computer screen, and is the color named ''green'' in X11. It is one of the three primary colors used in the RGB color space along with red and blue. The three additive primaries in the RGB color system are the three colors of light chosen such as to provide the maximum range of colors that are capable of being represented on a computer or television set. This color is also called ''regular green''. It is at precisely 120 degrees on the HSV color wheel, also known a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nature
Nature, in the broadest sense, is the physics, physical world or universe. "Nature" can refer to the phenomenon, phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word ...

HSV Color Space
HSL (for hue, saturation, lightness) and HSV (for hue, saturation, value; also known as HSB, for hue, saturation, brightness) are 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 HSL representation models the way different paints mix together to create color in the real world, with the ''lightness'' dimension resembling the varying amounts of black or white paint in the mixture (e.g. to create "light red", a red pigment can be mixed with white paint; this white paint corresponds to a high "lightness" value in the HSL representation). Fully saturated colors are placed around a circle at a lightness value of ½, with a lightness value of 0 or 1 corresponding to fully bla ...

Cyan
Cyan () is the color between green and blue on the visible spectrum of light. It is evoked by light with a predominant wavelength between 490 and 520 nm, between the wavelengths of green and blue. In the subtractive color system, or CMYK color model, which can be overlaid to produce all colors in paint and color printing, cyan is one of the primary colors, along with magenta and yellow. In the additive color system, or RGB 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. Mixing red light and cyan light at the right intensity will make white light. Colors in the cyan color range are teal, turquoise, electric blue, aquamarine, and others described as blue-green. Etymology and terminology Its name is derived from the Ancient Greek word ''kyanos'' (κύανος), meaning "dark blue enamel, Lapis lazuli". It ...

Psychedelic Art
Psychedelic art (also known as psychedelia) is art, graphics or visual displays related to or inspired by psychedelic experiences and hallucinations known to follow the ingestion of psychedelic drugs such as LSD, psilocybin, and DMT. The word "psychedelic" (coined by British psychologist Humphry Osmond) means "mind manifesting". By that definition, all artistic efforts to depict the inner world of the psyche may be considered "psychedelic". In common parlance "psychedelic art" refers above all to the art movement of the late 1960s counterculture, featuring highly distorted or surreal visuals, bright colors and full spectrums and animation (including cartoons) to evoke, convey, or enhance psychedelic experiences. Psychedelic visual arts were a counterpart to psychedelic rock music. Concert posters, album covers, liquid light shows, liquid light art, murals, comic books, underground newspapers and more reflected not only the kaleidoscopically swirling colour patterns of LSD hal ...

Angle Of View
The angle of view is the decisive variable for the visual perception of the size or projection of the size of an object. Angle of view and perception of size The perceived size of an object depends on the size of the image projected onto the retina. The size of the image depends on the angle of vision. A near and a far object can appear the same size if their edges produce the same angle of vision. With an optical device such as glasses or binoculars, microscope and telescope the angle of vision can be widened so that the object appears larger, which is favourable for the resolving power of the eye (see visual angle). Angle of view in photography In photography, angle of view (AOV) describes the angular extent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view. It is important to distinguish the angle of view from the angle of coverage, which describes the angle range that a lens can image. Typically the image ...

ChromaFlair
ChromaFlair is a pigment used in paint systems, primarily for automobiles. When the paint is applied, it changes color depending on the light source and viewing angle. It was created at JDS Uniphase and is used by DuPont and PPG. Names The paint system (and competing versions made by other companies) are known by a wide variety of proprietary names, including ''ChromaLusion'', ''ChromaPremier'', ''ColourShift'', ''Exclusive Line'', ''Extreme Colors'', ''Harlequin Color'', ''IllusionColor'', ''Maziora'', ''MultiTones'', ''MystiChrome'', ''Ch(K)ameleon'', ''Interference Fireglow'' and ''Paradis Spectrashine''. Effect The ChromaFlair effect is achieved by interfering with the reflection and refraction of light from the painted object's surface. The paint contains tiny synthetic flakes about one micrometer thick. The flakes are constructed of aluminium coated with glass-like magnesium fluoride embedded in semi-translucent chromium. The aluminium and chrome give the paint a vibrant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harlequin
Harlequin (; it, Arlecchino ; lmo, Arlechin, Bergamasque dialect, Bergamasque pronunciation ) is the best-known of the ''zanni'' or comic servant characters from the Italian language, Italian ''commedia dell'arte'', associated with the city of Bergamo. The role is traditionally believed to have been introduced by Zan Ganassa in the late 16th century, was definitively popularized by the Italian actor Tristano Martinelli in Paris in 1584–1585, and became a stock character after Martinelli's death in 1630. The Harlequin is characterized by his checkered costume. His role is that of a light-hearted, nimble, and Tricky slave, astute servant, often acting to thwart the plans of his master, and pursuing his own love interest, Columbina, with wit and resourcefulness, often competing with the sterner and melancholic Pierrot. He later develops into a prototype of the romantic hero. Harlequin inherits his physical agility and his trickster qualities, as well as his name, from a mischi ...

Tequila
Tequila (; ) is a liquor, distilled beverage made from the Agave tequilana, blue agave plant, primarily in the area surrounding the city of Tequila, Jalisco, Tequila northwest of Guadalajara, Jalisco, Guadalajara, and in the Jaliscan Highlands (''Los Altos (Jalisco), Los Altos de Jalisco'') of the central western Mexican state of Jalisco. The red volcanic soils in the region of Tequila are well suited for growing the blue agave, and more than 300 million of the plants are harvested there each year. Agave grows differently depending on the region. Blue agaves grown in the highlands Los Altos region are larger and sweeter in aroma and taste. Agaves harvested in the valley region have a more herbaceous fragrance and flavor. Due to its historical and cultural importance, the region near Tequila was declared a UNESCO World Heritage Site in 2006, the ''Agave Landscape and Ancient Industrial Facilities of Tequila''. Mexican laws state that tequila can be produced only in the state of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of HTML Color Names
Web colors are colors used in displaying web pages on the World Wide Web, and the methods for describing and specifying those colors. Colors may be specified as an RGB triplet or in hexadecimal format (a ''hex triplet'') or according to their common English names in some cases. A color tool or other graphics software is often used to generate color values. In some uses, hexadecimal color codes are specified with notation using a leading number sign (#). A color is specified according to the intensity of its red, green and blue components, each represented by eight bits. Thus, there are 24 bits used to specify a web color within the sRGB gamut, and 16,777,216 colors that may be so specified. Colors outside the sRGB gamut can be specified in Cascading Style Sheets by making one or more of the red, green and blue components negative or greater than 100%, so the color space is theoretically an unbounded extrapolation of sRGB similar to scRGB. Specifying a non-sRGB color this way re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of 8-bit Computer Hardware Palettes
This is a list of notable 8-bit computer palette (computing), color palettes, and graphics, which were primarily manufactured from 1975 to 1985. Although some of them use List of monochrome and RGB color formats#Regular RGB palettes, RGB palettes, more commonly they have 4, 16 or more color palettes that are not bit nor level combinations of RGB primaries, but fixed ROM/circuitry colors selected by the manufacturer. Due to mixed-bit architectures, the ''n''-bit distinction is not always a strict categorization. Another common mistake is the assumption that a color palette of a given computer is what it can display all at once. Resolution is also a crucial aspect when criticizing an 8-bit computer, as many offer different modes with different amounts of colors on screen, and different resolutions, with the intent of trading off resolution for color, and vice versa. : 3-bit RGB palettes Systems with a 3-bit RGB palette use 1 bit for each of the red, green and blue color components. ...

CIE Chromaticity Diagram
The CIE 1931 color spaces are the first defined quantitative links between distributions of wavelengths in the electromagnetic visible spectrum, and physiologically 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 system was designed in 1931 by the ''"Commission Internationale de l'éclairage"'', known in English as the International Commission on Illumination. 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 using ten observers and John Guild using seven observers. The experimental results were combined into the specification of the CIE RGB color space, from which the CIE XYZ color space was derived. T ...
