Color
Color (or colour in English in the Commonwealth of Nations, Commonwealth English; American and British English spelling differences#-our, -or, 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 spectra, emission, Reflection (physics), reflection and Transmittance, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Perforation, perforated edges so their pages can be removed from the books and used as individual sheets. Others may include a Narrative, story line and so are intended to be left intact. Today, many children's coloring books feature character (arts), popular characters. They are often used as promotional materials for motion pictures and television. 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 Europe and the United States as part of the "democratization of art" process, inspired by a seri ...

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 separation, 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 w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graph Coloring
In graph theory, graph coloring is a methodic assignment of labels traditionally called "colors" to elements of a Graph (discrete mathematics), graph. The assignment is subject to certain constraints, such as that no two adjacent elements have the same color. Graph coloring is a special case of graph labeling. In its simplest form, it is a way of coloring the Vertex (graph theory), 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 (graph theory), edges 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 (graph theory), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hair Coloring
Hair coloring, or hair dyeing, is the practice of changing the color of the hair on humans' heads. The main reasons for this are cosmetic: to cover gray or white hair, to alter hair to create a specific look, to change a color to suit preference 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. Hair coloring is very popular, with 50-80% of women in the United States, Europe, and Japan having reported using hair dye. At-home coloring in the United States reached sales of $1.9 billion in 2011 and was expected to rise to $2.2 billion by 2016. History The dyeing of hair is an ancient art that involves treatment of the hair with various chemical compounds. Assyrian herbals dating back to contain some of the oldest recipes for cosmetic preparations known, including hair dye. The ancient Egyptian Ebers Papyrus, , has recipes for dyein ...

Food Coloring
Food coloring, color additive or colorant is any dye, pigment, or substance that imparts color when it is added to food or beverages. Colorants can be supplied as liquids, powders, gels, or pastes. Food coloring is commonly used in commercial products and in domestic cooking. Food colorants are also used in various non-food applications, including cosmetics, pharmaceuticals, home craft projects, and medical devices. Some colorings may be natural, such as with carotenoids and anthocyanins extracted from plants or cochineal from insects, or may be synthesized, such as tartrazine yellow. In the manufacturing of foods, beverages and cosmetics, the safety of colorants is under constant scientific review and certification by national regulatory agencies, such as the European Food Safety Authority (EFSA) and US Food and Drug Administration (FDA), and by international reviewers, such as the Joint FAO/WHO Expert Committee on Food Additives. Purpose of food coloring People asso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Map Coloring
In cartographic design, map coloring is the act of choosing colors as a form of map symbol to be used on a map. 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 map. In many cultures, certain colors have connotations. These connotations lie under a field of study called color symbolism. For example, coloring a certain nation a color t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
