Color Analysis (art)
Color analysis (American English; colour analysis in Commonwealth English), also known as personal color analysis (PCA), seasonal color analysis, or skin-tone matching, is a term often used within the cosmetics and fashion industry to describe a method of determining the colors of clothing and makeup that harmonizes with a person's skin complexion, eye color, and hair color for use in wardrobe planning and style consulting. It is generally agreed that the wrong colors will draw attention to such flaws as wrinkles or uneven skin tone while harmonious colors will enhance the natural beauty of the individual making them appear healthy and fresh-faced. By the 1920s, a color revolution had occurred in the United States with the development of new color industries and the possibility of producing color swatch books used as a marketing tool. Personal color analysis reached a height in popularity in the early 1980s with a recent resurgence in the 2010s after further development and pr ...

American English
American English, sometimes called United States English or U.S. English, is the set of varieties of the English language native to the United States. English is the most widely spoken language in the United States and in most circumstances is the de facto common language used in government, education and commerce. Since the 20th century, American English has become the most influential form of English worldwide. American English varieties include many patterns of pronunciation, vocabulary, grammar and particularly spelling that are unified nationwide but distinct from other English dialects around the world. Any American or Canadian accent perceived as lacking noticeably local, ethnic or cultural markers is popularly called "General" or "Standard" American, a fairly uniform accent continuum native to certain regions of the U.S. and associated nationally with broadcast mass media and highly educated speech. However, historical and present linguistic evidence does not sup ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luminance
Luminance is a photometric measure of the luminous intensity per unit area of light travelling in a given direction. It describes the amount of light that passes through, is emitted from, or is reflected from a particular area, and falls within a given solid angle. Brightness is the term for the ''subjective'' impression of the ''objective'' luminance measurement standard (see for the importance of this contrast). The SI unit for luminance is candela per square metre (cd/m2). A non-SI term for the same unit is the nit. The unit in the Centimetre–gram–second system of units (CGS) (which predated the SI system) is the stilb, which is equal to one candela per square centimetre or 10 kcd/m2. Description Luminance is often used to characterize emission or reflection from flat, diffuse surfaces. Luminance levels indicate how much luminous power could be detected by the human eye looking at a particular surface from a particular angle of view. Luminance is thus an ...

Rose Zepherine Drouhin Img 1838
A rose is either a woody perennial flowering plant of the genus ''Rosa'' (), in the family Rosaceae (), or the flower it bears. There are over three hundred species and tens of thousands of cultivars. They form a group of plants that can be erect shrubs, climbing, or trailing, with stems that are often armed with sharp prickles. Their flowers vary in size and shape and are usually large and showy, in colours ranging from white through yellows and reds. Most species are native to Asia, with smaller numbers native to Europe, North America, and northwestern Africa. Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant. Roses have acquired cultural significance in many societies. Rose plants range in size from compact, miniature roses, to climbers that can reach seven meters in height. Different species hybridize easily, and this has been used in the development of the wide range of garden roses. Etymology The name ''rose'' comes from La ...

Colorful Spring Garden
Color (American English) or colour (British English) is the visual perceptual property deriving from the spectrum of light interacting with the photoreceptor cells of the eyes. Color categories and physical specifications of color are associated with objects or materials based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space, colors can be identified numerically by their coordinates. Because perception of color stems from the varying spectral sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. These physical or physiological quantifications of color, however, do not fully explain the psychophysical perception of color appearance. Color science includes the perception of color by the eye and brain, the origin of color in materials, color theory in art, and the physics of electroma ...

Bernice Kentner
Bernice Kentner (1929–2018) was an American cosmetologist, color theorist, and author. Background Bernice Kentner was born in Cheyenne, Wyoming and later moved to North Platte, Nebraska. In the 1980s, Kentner relocated to Concord, California. Bernice Kentner was a leading proponent of seasonal color analysis in the 1970s and 1980s. By the 1990s, Jo Peddicord still considered Kentner's philosophy of color to be one of the most prominent color analysis systems in the United States, and Peddicord acknowledged that Kentner had an international following. In 2003, The Register-Guard stated that Kentner's book ''Color Me a Season'' "helped spur the 1980s boom in color analysis." In the 2010s, some authors argued that Kentner's system had become outdated, such as June McLeod, who wrote in 2016 that "today there are few people in the colour world who still follow her work by using the four season system." Seasonal color analysis The color analysis system developed by Bernice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemoglobin
Hemoglobin (haemoglobin BrE) (from the Greek word αἷμα, ''haîma'' 'blood' + Latin ''globus'' 'ball, sphere' + ''-in'') (), abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein present in red blood cells (erythrocytes) of almost all vertebrates (the exception being the fish family Channichthyidae) as well as the tissues of some invertebrates. Hemoglobin in blood carries oxygen from the respiratory organs (''e.g.'' lungs or gills) to the rest of the body (''i.e.'' tissues). There it releases the oxygen to permit aerobic respiration to provide energy to power functions of an organism in the process called metabolism. A healthy individual human has 12to 20grams of hemoglobin in every 100mL of blood. In mammals, the chromoprotein makes up about 96% of the red blood cells' dry content (by weight), and around 35% of the total content (including water). Hemoglobin has an oxygen-binding capacity of 1.34mL O2 per gram, which increases the total blood oxygen ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carotene
The term carotene (also carotin, from the Latin ''carota'', "carrot") is used for many related unsaturated hydrocarbon substances having the formula C40Hx, which are synthesized by plants but in general cannot be made by animals (with the exception of some aphids and spider mites which acquired the synthesizing genes from fungi). Carotenes are photosynthetic pigments important for photosynthesis. Carotenes contain no oxygen atoms. They absorb ultraviolet, violet, and blue light and scatter orange or red light, and (in low concentrations) yellow light. Carotenes are responsible for the orange colour of the carrot, after which this class of chemicals is named, and for the colours of many other fruits, vegetables and fungi (for example, sweet potatoes, chanterelle and orange cantaloupe melon). Carotenes are also responsible for the orange (but not all of the yellow) colours in dry foliage. They also (in lower concentrations) impart the yellow coloration to milk-fat and butter. Om ...

Melanin
Melanin (; from el, μέλας, melas, black, dark) is a broad term for a group of natural pigments found in most organisms. Eumelanin is produced through a multistage chemical process known as melanogenesis, where the oxidation of the amino acid tyrosine is followed by polymerization. The melanin pigments are produced in a specialized group of cells known as melanocytes. Functionally, eumelanin serves as protection against UV radiation. There are five basic types of melanin: eumelanin, pheomelanin, neuromelanin, allomelanin and pyomelanin. The most common type is eumelanin, of which there are two types— brown eumelanin and black eumelanin. Pheomelanin, which is produced when melanocytes are malfunctioning due to derivation of the gene to its recessive format is a cysteine-derivative that contains poly benzothiazine portions that are largely responsible for the of red yellow tint given to some skin or hair colors. Neuromelanin is found in the brain. Research has been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johannes Itten
Johannes Itten (11 November 1888 – 25 March 1967) was a Swiss expressionist painter, designer, teacher, writer and theorist associated with the Bauhaus (''Staatliches Bauhaus'') school. Together with German-American painter Lyonel Feininger and German sculptor Gerhard Marcks, under the direction of German architect Walter Gropius, Itten was part of the core of the Weimar Bauhaus. Life and work He was born in Südern-Linden, Switzerland. From 1904 to 1908 he trained as an elementary school teacher. Beginning in 1908 he taught using methods developed by the creator of the kindergarten concept, Friedrich Fröbel, and was exposed to the ideas of psychoanalysis. In 1909 he enrolled at the École des Beaux-Arts in Geneva but was unimpressed with the educators there, and returned to Bern. Itten's studies at the Bern-Hofwil Teachers' Academy with Ernst Schneider proved seminal for his later work as a master at the Bauhaus. Itten adopted principles espoused by Schneider, includ ...

CIELAB Color Space
The CIELAB color space, also referred to as ''L*a*b*'' , is a color space defined by the International Commission on Illumination (abbreviated CIE) in 1976. (Referring to CIELAB as "Lab" without asterisks should be avoided to prevent confusion with Hunter Lab). It expresses color as three values: ''L*'' for perceptual lightness and ''a*'' and ''b*'' for the four unique colors of human vision: red, green, blue and yellow. CIELAB was intended as a perceptually uniform space, where a given numerical change corresponds to a similar perceived change in color. While the LAB space is not truly perceptually uniform, it nevertheless is useful in industry for detecting small differences in color. Like the CIEXYZ space it derives from, CIELAB color space is a device-independent, "standard observer" model. The colors it defines are not relative to any particular device such as a computer monitor or a printer, but instead relate to the CIE standard observer which is an averaging of the r ...

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 supplies 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 Research Laboratory which was funded by the Munsell family. A few years later, the Munsell Color Foundation and the Laboratory moved to Baltimore, Maryland, to be close to the National Bureau of Standards and Johns Hopkins University. Alexander Munsell contributed his times attending to Johns Hopkins University and under ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
