Color
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 electr ...

Coloring Book
A coloring book (British English: colouring-in book, colouring book, or colouring page) is a type of book containing line art to which people are intended to add color using crayons, colored pencils, marker pens, paint or other artistic media. Traditional coloring books and coloring pages are printed on paper or card. Some coloring books have perforated edges so their pages can be removed from the books and used as individual sheets. Others may include a story line and so are intended to be left intact. Today, many children's coloring books feature popular cartoon characters. They are often used as promotional materials for animated motion pictures. Coloring books may also incorporate other activities such as connect the dots, mazes and other puzzles. Some also incorporate the use of stickers. History Paint books and coloring books emerged in the United States as part of the "democratization of art" process, inspired by a series of lectures by British artist Joshua Reynold ...

Colorist
In comics, a colorist is responsible for adding color to black-and-white line art. For most of the 20th century this was done using brushes and dyes which were then used as guides to produce the printing plates. Since the late 20th century it is most often done using digital media, with printing separations produced electronically. Although most American colorists work directly for comics publishers (either as employees or freelancers), there are a few coloring studios which offer their services to publishers. American Color, Olyoptics, Digital Chameleon were the companies notable in this field. History Originally, comics were colored by cutting out films of various densities in the appropriate shapes to be used in producing color-separated printing plates. The typical colorist worked from photocopies of the inked pages, which they colored with special dyes. Dr. Martin's Dyes was a brand notable in this field within the comic strip industry. CMYK codes were written on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graph Coloring
In graph theory, graph coloring is a special case of graph labeling; it is an assignment of labels traditionally called "colors" to elements of a graph subject to certain constraints. In its simplest form, it is a way of coloring the vertices of a graph such that no two adjacent vertices are of the same color; this is called a vertex coloring. Similarly, an edge coloring assigns a color to each edge so that no two adjacent edges are of the same color, and a face coloring of a planar graph assigns a color to each face or region so that no two faces that share a boundary have the same color. Vertex coloring is often used to introduce graph coloring problems, since other coloring problems can be transformed into a vertex coloring instance. For example, an edge coloring of a graph is just a vertex coloring of its line graph, and a face coloring of a plane graph is just a vertex coloring of its dual. However, non-vertex coloring problems are often stated and studied as-is. This is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hair Coloring
Hair coloring, or hair dyeing, is the practice of changing the hair color. The main reasons for this are cosmetic: to cover gray or white hair, to change to a color regarded as more fashionable or desirable, or to restore the original hair color after it has been discolored by hairdressing processes or sun bleaching. Hair coloring can be done professionally by a hairdresser or independently at home. Today, hair coloring is very popular, with 75% of women and 18% of men living in Copenhagen having reported using hair dye (according to a study by the University of Copenhagen). At-home coloring in the United States reached $1.9 billion in 2011 and was expected to rise to $2.2 billion by 2016. History Diodorus Siculus, a Greek historian, described in detail how Celtic people dyed their hair blonde: "Their aspect is terrifying... They are very tall in stature, with rippling muscles under clear white skin. Their hair is blond, but not naturally so: they bleach it, to this day, artifi ...

Food Coloring
Food coloring, or color additive, is any dye, pigment, or substance that imparts color when it is added to food or drink. They come in many forms consisting of liquids, powders, gels, and pastes. Food coloring is used in both commercial food production and domestic cooking. Food colorants are also used in a variety of non-food applications, including cosmetics, pharmaceuticals, home craft projects, and medical devices. Purpose of food coloring People associate certain colors with certain flavors, and the color of food can influence the perceived flavor in anything from candy to wine. Sometimes, the aim is to simulate a color that is perceived by the consumer as natural, such as adding red coloring to glacé cherries (which would otherwise be beige), but sometimes it is for effect, like the green ketchup that Heinz launched in 2000. Color additives are used in foods for many reasons including: * To make food more attractive, appealing, appetizing, and informative * Offset c ...

Hand-colouring Of Photographs
Hand-colouring (or hand-coloring) refers to any method of manually adding colour to a monochrome photograph, generally either to heighten the realism of the image or for artistic purposes. Hand-colouring is also known as hand painting or overpainting. Typically, watercolours, oils, crayons or pastels, and other paints or dyes are applied to the image surface using brushes, fingers, cotton swabs or airbrushes. Hand-coloured photographs were most popular in the mid- to late-19th century before the invention of colour photography and some firms specialised in producing hand-coloured photographs. History Pre-1900 Monochrome (black and white) photography was first exemplified by the daguerreotype in 1839 and later improved by other methods including: calotype, ambrotype, tintype, albumen print and gelatin silver print. The majority of photography remained monochrome until the mid-20th century, although experiments were producing colour photography as early as 1855 and some photogr ...

Map Coloring
In cartography, map coloring is the act of choosing colors as a form of map symbol to be used on a map. In mathematics, map coloring is the act of assigning colors to features of a map such that no two adjacent features have the same color using the minimum number of colors. Cartography Color is a very useful attribute to depict different features on a map. Typical uses of color include displaying different political divisions, different elevations, or different kinds of roads. A choropleth map is a thematic map in which areas are colored differently to show the measurement of a statistical variable being displayed on the map. The choropleth map provides an easy way to visualize how a measurement varies across a geographic area or it shows the level of variability within a region. In addition to choropleth maps, a cartographer should strive to depict colors effectively on any kind of map. Displaying the data in different hues can greatly affect the understanding or feel of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Color Code (other)
Color code or color coding may refer to: *Color code, standardized mappings from systems of colors to meanings, as in traffic lights * Color coding technology for visualization, methods of choosing meanings for colors in information visualization *Color-coding, a technique for speeding up pattern matching algorithms by randomly assigning colors to objects * Color-code (band), a Japanese all-female music group *Colour Coding, an Australian indie pop band * Color Code Personality Profile, a classification of people's motivations into four types associated with four colors *Color-coding, formally called Unified Vehicular Volume Reduction Program, a system restricting when cars can drive in Metro Manila * Gender color-coding, the stereotyped association of color with gender in some cultures *Electronic color code, the color code used to identify electronic parts *Web colors, defined with a hexadecimal triplet code See also * Coloring (other) * Blue code * Code Red (disambi ...
