Avocado Green
Shades of chartreuse are listed below. Historically, many of these colors have gone under the name of either yellow or green, as the specifics of their color composition was not known until later. Wrapping the spectrum into a color wheel In a color proximity sense, a primary color has a color range of 120° (60° on each side of the color's hue) and any color has to be within that range to be considered a variation of that color. Secondary colors have a color range of 60° (30°), tertiary colors have a color range of 30° (15°), quaternary colors have a color range of 15° (7.5°), quinary colors have a color range of 7.5° (3.75°), and so on. Because chartreuse is located at a hue angle of 90°, it has a tertiary color range of 75° and 105°, and any color out of this range is more related to yellow or green than chartreuse. If the visible spectrum is wrapped to form a color wheel, chartreuseadditive tertiary appears midway between yellow and green: Definitions of char ...

Western Daily Press
The ''Western Daily Press'' is a regional newspaper covering parts of South West England, mainly Gloucestershire, Wiltshire and Somerset as well as the metropolitan areas of Bath and North East Somerset and the Bristol area. It is published Monday to Saturday in Bristol, UK. The majority of its readers are in rural areas, small towns and villages throughout the region and the paper's coverage of rural, agricultural and countryside issues is particularly strong. It also has a good record in picking up quirky and bizarre stories which would otherwise not be publicised. Politically it tends to be conservative although its coverage of the UK ban on fox hunting was neutral, recognising that even in rural areas people are very divided on the issue. Founding It was founded by Scottish businessman Peter Stewart Macliver and Newcastle journalist Walter Reid and first published on 1 June 1858. Macliver went on to found the '' Bristol Observer''. Twentieth century The ''Western Daily'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spectrum
A spectrum (plural ''spectra'' or ''spectrums'') is a condition that is not limited to a specific set of values but can vary, without gaps, across a continuum. The word was first used scientifically in optics to describe the rainbow of colors in visible light after passing through a prism. As scientific understanding of light advanced, it came to apply to the entire electromagnetic spectrum. It thereby became a mapping of a range of magnitudes (wavelengths) to a range of qualities, which are the perceived "colors of the rainbow" and other properties which correspond to wavelengths that lie outside of the visible light spectrum. Spectrum has since been applied by analogy to topics outside optics. Thus, one might talk about the " spectrum of political opinion", or the "spectrum of activity" of a drug, or the "autism spectrum". In these uses, values within a spectrum may not be associated with precisely quantifiable numbers or definitions. Such uses imply a broad range of condition ...

Tint
In color theory, a tint is a mixture of a color with white, which increases lightness, while a shade is a mixture with black, which increases darkness. Both processes affect the resulting color mixture's relative saturation. A tone is produced either by mixing a color with gray, or by both tinting and shading. Mixing a color with any neutral color (including black, gray, and white) reduces the chroma, or colorfulness, while the hue (the relative mixture of red, green, blue, etc. depending on the colorspace) remains unchanged. In the graphic arts, especially printmaking and drawing, "tone" has a different meaning, referring to areas of continuous color, produced by various means, as opposed to the linear marks made by an engraved or drawn line. In common language, the term ''shade'' can be generalized to encompass any varieties of a particular color, whether technically they are shades, tints, tones, or slightly different hues. Meanwhile, the term ''tint'' can be gener ... [...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] |
Viridian Design Movement
The Viridian Design Movement was an aesthetic movement focused on concepts from bright green environmentalism. The name was chosen to refer to a shade of green that does not quite look natural, indicating that the movement was about innovative design and technology, in contrast with the "leaf green" of traditional environmentalism. The movement tied together environmental design, techno-progressivism, and global citizenship. It was founded in 1998 by Bruce Sterling, a postcyberpunk science fiction author. Sterling always remained the central figure in the movement, with Alex Steffen perhaps the next best-known. Steffen, Jamais Cascio, and Jon Lebkowsky, along with some other frequent contributors to Sterling's Viridian notes, formed the Worldchanging blog. Sterling wrote the introduction to Worldchanging's book (''Worldchanging: A Users Guide for the 21st Century''), which (according to Ross Robertson) is considered the definitive volume on bright green thinking. Sterling formally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bright Green Environmentalism
Bright green environmentalism is an ideology based on the belief that the convergence of technological change and social innovation provides the most successful path to sustainable development. Origin and evolution of bright green thinking The term ''bright green'', coined in 2003 by writer Alex Steffen, refers to the fast-growing new wing of environmentalism, distinct from traditional forms. Bright green environmentalism aims to provide prosperity in an ecologically sustainable way through the use of new technologies and improved design. Proponents promote and advocate for green energy, electric automobiles, efficient manufacturing systems, bio and nanotechnologies, ubiquitous computing, dense urban settlements, closed loop materials cycles and sustainable product designs. ''One-planet living'' is a commonly used phrase. Their principal focus is on the idea that through a combination of well-built communities, new technologies and sustainable living practices, quality of life ...

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 ...

Visual Spectrum
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called ''visible light'' or simply light. A typical human eye will respond to wavelengths from about 380 to about 750 nanometers. In terms of frequency, this corresponds to a band in the vicinity of 400–790 terahertz. These boundaries are not sharply defined and may vary per individual. Under optimal conditions these limits of human perception can extend to 310 nm (ultraviolet) and 1100 nm (near infrared). The optical spectrum is sometimes considered to be the same as the visible spectrum, but some authors define the term more broadly, to include the ultraviolet and infrared parts of the electromagnetic spectrum as well. The spectrum does not contain all the colors that the human visual system can distinguish. '' Unsaturated colors'' such as pink, or purple variations like magenta, for example, are absen ...

Nanometer
330px, Different lengths as in respect to the molecular scale. The nanometre (international spelling as used by the International Bureau of Weights and Measures; SI symbol: nm) or nanometer (American and British English spelling differences#-re, -er, American spelling) is a units of measurement, unit of length in the International System of Units (SI), equal to one billionth (short scale) of a metre () and to 1000 picometres. One nanometre can be expressed in scientific notation as , and as metres. History The nanometre was formerly known as the millimicrometre – or, more commonly, the millimicron for short – since it is of a micron (micrometre), and was often denoted by the symbol mμ or (more rarely and confusingly, since it logically should refer to a ''millionth'' of a micron) as μμ. Etymology The name combines the SI prefix ''nano-'' (from the Ancient Greek , ', "dwarf") with the parent unit name ''metre'' (from Greek , ', "unit of measurement"). ...

Chartreuse (color)
Chartreuse (, , ), also known as yellow-green, is a color between yellow and green. It was named because of its resemblance to the green color of a French liqueur called '' green chartreuse'', introduced in 1764. Similarly, ''chartreuse yellow'' is a yellow color mixed with a small amount of green; it was named because of its resemblance to the color of another French liqueur called '' yellow chartreuse'', introduced in 1838. Shades of chartreuse History and etymology The French word ''chartreuse'' means "charterhouse". The monasteries of the monks of the Carthusian order, of which the first one was established in 1082 by Saint Bruno, are called charter houses because they were chartered—and given generous material support—by the Duke of Burgundy, known as Philip the Bold, when he took over the area in 1378. Philip the Bold's elaborately decorated tomb was initially installed at a Carthusian charterhouse when he died in 1404. These monks started producing Chartreuse lique ...
