Tertiary Colors
A secondary color is a color made by mixing two primary colors of a given color model in even proportions. Combining two secondary colors in the same manner produces a tertiary color. Secondary colors are special in traditional color theory, but have no special meaning in color science. Overview Primary color In traditional color theory, it is believed that all colors can be mixed from 3 universal primary - or pure - colors, which were originally believed to be red, yellow and blue pigments (representing the RYB color model). However, modern color science does not recognize universal primary colors and only defines primary colors for a given color model or color space. RGB and CMYK color models are popular color models in modern color science, but are only chosen as efficient primaries, in that their combination leads to a large gamut. However, any three primaries can produce a viable color gamut. The RYB model continues to be used and taught as a color model for practical c ...

Color Diagram Charles Hayter
Color (or colour in Commonwealth English; see spelling differences) is the visual perception based on the electromagnetic spectrum. Though color is not an inherent property of matter, color perception is related to an object's light absorption, emission, reflection and transmission. For most humans, colors are perceived in the visible light spectrum with three types of cone cells ( trichromacy). Other animals may have a different number of cone cell types or have eyes sensitive to different wavelengths, such as bees that can distinguish ultraviolet, and thus have a different color sensitivity range. Animal perception of color originates from different light wavelength or spectral sensitivity in cone cell types, which is then processed by the brain. Colors have perceived properties such as hue, colorfulness (saturation), and luminance. Colors can also be additively mixed (commonly used for actual light) or subtractively mixed (commonly used for materials). If the colors ...

Green
Green is the color between cyan 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 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. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content. During post-classical and early modern Europe, green was the color commonly associated with wealth, merchants, bankers, and the gentry, whil ...

SRGB
sRGB (standard RGB) is a colorspace, for use on monitors, printers, and the World Wide Web. It was initially proposed by HP and Microsoft in 1996 and became an official standard of the International Electrotechnical Commission (IEC) as IEC 61966-2-1:1999. It is the current standard colorspace for the web, and it is usually the assumed colorspace for images that do not have an embedded color profile. The sRGB standard uses the same color primaries and white point as the ITU-R BT.709 standard for HDTV, but a different transfer function (or gamma) compatible with the era's CRT displays, and assumes a viewing environment closer to typical home and office viewing conditions. Matching the behavior of PC video cards and CRT displays greatly aided sRGB's popularity. History By the 1970s, most computers translated 8-bit digital data fairly linearly to a signal that was sent to a video monitor. However video monitors and TVs produced a brightness that was not linear with the input ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rose (color)
Rose is the color halfway between red, magenta and white on the HSL and HSV, HSV color wheel, also known as the :File:RGB color wheel.svg, RGB color wheel, on which it is at hue angle of 330 degrees. Rose, or vivid pink is one of the tertiary colors on the HSV (RGB) color wheel. The complementary colors, complementary color of rose is spring green. Sometimes rose is quoted instead as the Web color, web-safe color FF00CC, which is closer to magenta than to red, corresponding to a hue angle near 320 degrees, or the web-safe color FF0077, which is closer to red than magenta, corresponding to a hue angle of about 340 degrees. Shades of rose Etymology of rose The first recorded use of ''rose'' as a color name in English was in 1382.Maerz and Paul ''A Dictionary of Color'' New York:1930 McGraw-Hill Page 203 The etymology of the color name rose is the same as that of the name of the rose flower. The name originates from Latin ''rosa'', borrowed through Oscan language, Oscan fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Violet (color)
Violet is the color of light at the short wavelength end of the visible spectrum. It is one of the seven colors that Isaac Newton labeled when dividing the spectrum of visible light in 1672. Violet light has a wavelength between approximately 380 and 450 nanometers. The color's name is derived from the ''Viola'' genus of flowers. In the RGB color model used in computer and television screens, violet is produced by mixing red and blue light, with more blue than red. In the RYB color model historically used by painters, violet is created with a combination of red and blue pigments and is located between blue and purple on the color wheel. In the CMYK color model used in printing, violet is created with a combination of magenta and cyan pigments, with more magenta than cyan. On the RGB/ CMY( K) color wheel, violet is located between blue and magenta. Violet is closely associated with purple. In optics, violet is a spectral color (referring to the color of different single wav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Azure (color)
Azure ( , ) is the color between cyan and blue on the visible spectrum, spectrum of visible light. It is often described as sky blue, the color of the sky on a clear day. On the :File:RGB color wheel.svg, RGB color wheel, "azure" (Web colors#Hex triplet, hexadecimal #0080FF) is defined as the color at 210 degrees, i.e., the hue halfway between Shades of blue#Blue (RGB) (X11 blue), blue and cyan. In the RGB color model, used to create all the colors on a television or computer screen, azure is created by adding a 50% of green light to a 100% of blue light. In the X11 color names, X11 color system, which became a model for early web colors, azure is depicted as a pale cyan or white cyan. Etymology and history The color azure ultimately takes its name from the vivid-blue gemstone lapis lazuli, a metamorphic rock. ' is the Latin word for "stone" and ' is the genitive form of the Medieval Latin ', which is taken from the Arabic ''lāzaward'' (), itself from the Persian lan ...

Chartreuse (color)
Chartreuse (, , ), also known as yellow-green or greenish yellow, is a color between yellow and green. It was named because of its resemblance to the French liqueur green chartreuse, introduced in 1764. Similarly, chartreuse yellow is a yellow color mixed with a small amount of green, named after the drink yellow chartreuse. During the 2000s, yellow-green, as well as other shades of bright green like lime green, became very popular when various tech companies used it in office decor and other products, and with the popularity and success of the ''Shrek'' franchise. Shades History and etymology The name ''Carthusian'' is derived from the Chartreuse Mountains in the French Prealps: Bruno of Cologne built his first hermitage in a valley of these mountains. These names were adapted to the English '' charterhouse'', meaning a Carthusian monastery. These monks started producing Chartreuse liqueur in 1737. In nature Yellow-green algae, also called ''Xanthophytes'', are a class ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orange (colour)
Orange is the colour between yellow and red on the spectrum of visible light. The human eyes perceive orange when observing light with a dominant wavelength between roughly 585 and 620 nanometres. In traditional colour theory, it is a secondary colour of pigments, produced by mixing yellow and red. In the RGB colour model, it is a tertiary colour. It is named after the orange (fruit), fruit of the same name. The orange colour of many fruits and vegetables, such as carrots, pumpkins, sweet potatoes, and Orange (fruit), oranges, comes from carotenes, a type of photosynthetic pigment. These pigments convert the light energy that the plants absorb from the Sun into chemical energy for the plants' growth. Similarly, the hues of autumn leaves are from the same pigment after chlorophyll is removed. In Europe and the United States, surveys show that orange is the colour most associated with amusement, the unconventional, extroversion, warmth, fire, energy, activity, danger, taste and a ...

Subtractive Mixing
Subtractive color or subtractive color mixing predicts the spectral power distribution of light after it passes through successive layers of partially absorbing media. This idealized model is the essential principle of how dyes and pigments are used in color printing and photography, where the perception of color is elicited after white light passes through microscopic "stacks" of partially absorbing media, allowing some wavelengths of light to reach the eye and not others. It is also a concept seen in painting, wherein the colors are mixed or applied in successive layers. Process The subtractive color mixing model predicts the resultant spectral power distribution of light filtered through overlaid partially absorbing materials on a reflecting or transparent surface. Each layer partially absorbs some wavelengths of light from the illumination spectrum while letting others pass through, resulting in a colored appearance. The resultant spectral power distribution is predicted b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CMY Color Model
The CMYK color model (also known as process color, or four color) is a subtractive color model, based on the CMY color model, used in color printing, and is also used to describe the printing process itself. The abbreviation ''CMYK'' refers to the four ink plates used: cyan, magenta, yellow, and key (most often black). The CMYK model works by partially or entirely masking colors on a lighter, usually white, background. The ink reduces the light that would otherwise be reflected. Such a model is called ''subtractive'', as inks ''subtract'' some colors from white light; in the CMY model, white light minus red leaves cyan, white light minus green leaves magenta, and white light minus blue leaves yellow. In additive color models, such as RGB, white is the ''additive'' combination of all primary colored lights, and black is the absence of light. In the CMYK model, it is the opposite: white is the natural color of the paper or other background, and black results from a full c ...

Magenta
Magenta () is a purple-red color. On color wheels of the RGB color model, RGB (additive) and subtractive color, CMY (subtractive) color models, it is located precisely midway between blue and red. It is one of the four colors of ink used in color printing by most Color printing, color printers, along with yellow, cyan, and black to make all the other colors. Magenta is a color made by mixing red and blue. The tone of magenta used in printing, Shades of magenta, printer's magenta, is redder than the magenta of the RGB (additive) model, the former being closer to Rose (color), rose. Magenta took its name from an aniline dye made and patented in 1859 by the French chemist François-Emmanuel Verguin, who originally called it ''fuchsine''. It was renamed to celebrate the French-Sardinian victory under French Emperor Napoleon III at the Battle of Magenta against the larger army of the Austrian Empire on 4 June 1859 near the Italian town of Magenta, Lombardy, Magenta, at the time in Au ...
