RYB Colour Model
RYB (an abbreviation of red–yellow–blue) is a subtractive color model used in art and applied design in which red, yellow, and blue pigments are considered primary colors. Under traditional color theory, this set of primary colors was advocated by Moses Harris, Michel Eugène Chevreul, Johannes Itten and Josef Albers, and applied by countless artists and designers. The RYB color model underpinned the color curriculum of the Bauhaus, Ulm School of Design and numerous art and design schools that were influenced by the Bauhaus, including the IIT Institute of Design (founded as the New Bauhaus), Black Mountain College, Design Department Yale University, the Shillito Design School, Sydney, and Parsons School of Design, New York. In this context, the term ''primary color'' refers to three exemplar colors (red, yellow, and blue) as opposed to specific pigments. As illustrated, in the RYB color model, red, yellow, and blue are intermixed to create secondary color segments of o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromatography 1841 Field
In chemical analysis, chromatography is a laboratory technique for the Separation process, separation of a mixture into its components. The mixture is dissolved in a fluid solvent (gas or liquid) called the ''mobile phase'', which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which a material called the ''stationary phase'' is fixed. Because the different constituents of the mixture tend to have different affinities for the stationary phase and are retained for different lengths of time depending on their interactions with its surface sites, the constituents travel at different apparent velocities in the mobile fluid, causing them to separate. The separation is based on the differential partitioning between the mobile and the stationary phases. Subtle differences in a compound's partition coefficient result in differential retention on the stationary phase and thus affect the separation. Chromatography may be ''preparative'' or ''analytical' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Mountain College
Black Mountain College was a Private college, private Liberal arts colleges in the United States, liberal arts college in Black Mountain, North Carolina. It was founded in 1933 by John Andrew Rice, Theodore Dreier, and several others. The college was ideologically organized around John Dewey's educational philosophy, which emphasized holistic learning and the study of art as central to a Liberal arts, liberal arts education.

Aristotle
Aristotle (; 384–322 BC) was an Ancient Greek philosophy, Ancient Greek philosopher and polymath. His writings cover a broad range of subjects spanning the natural sciences, philosophy, linguistics, economics, politics, psychology, and the arts. As the founder of the Peripatetic school of philosophy in the Lyceum (classical), Lyceum in Athens, he began the wider Aristotelianism, Aristotelian tradition that followed, which set the groundwork for the development of modern science. Little is known about Aristotle's life. He was born in the city of Stagira (ancient city), Stagira in northern Greece during the Classical Greece, Classical period. His father, Nicomachus (father of Aristotle), Nicomachus, died when Aristotle was a child, and he was brought up by a guardian. At around eighteen years old, he joined Plato's Platonic Academy, Academy in Athens and remained there until the age of thirty seven (). Shortly after Plato died, Aristotle left Athens and, at the request ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Wolfgang Von Goethe
Johann Wolfgang (von) Goethe (28 August 1749 – 22 March 1832) was a German polymath who is widely regarded as the most influential writer in the German language. His work has had a wide-ranging influence on Western literature, literary, Political philosophy#European Enlightenment, political, and Western philosophy, philosophical thought in the Western world from the late 18th century to the present.. A poet, playwright, novelist, scientist, statesman, theatre-director, and critic, Johann Wolfgang von Goethe bibliography, his works include plays, poetry and aesthetic criticism, as well as treatises on botany, anatomy, and colour.

Theory Of Colours
''Theory of Colours'' () is a book by Johann Wolfgang von Goethe about the poet's views on the nature of colours and how they are perceived by humans. It was published in German in 1810 and in English in 1840. The book contains detailed descriptions of phenomena such as Complementary colours, coloured shadows, refraction, and chromatic aberration. The book is a successor to two short essays titled "Contributions to Optics" (). The work originated in Goethe's occupation with painting and primarily had its influence in the arts, with painters such as (Philipp Otto Runge, J. M. W. Turner, the Pre-Raphaelites, Hilma af Klint, and Wassily Kandinsky). Although Goethe's work was rejected by some physicists, a number of philosophers and physicists have concerned themselves with it, including Thomas Johann Seebeck, Arthur Schopenhauer (see: ''On Vision and Colors''), Hermann von Helmholtz, Ludwig Wittgenstein, Werner Heisenberg, Kurt Gödel, and Mitchell Feigenbaum. ...

Mezzotint
Mezzotint is a monochrome printmaking process of the intaglio (printmaking), intaglio family. It was the first printing process that yielded half-tones without using line- or dot-based techniques like hatching, cross-hatching or stipple. Mezzotint achieves tonality by roughening a metal plate with thousands of little dots made by a metal tool with small teeth, called a "rocker". In printing, the tiny pits in the plate retain the ink when the face of the plate is wiped clean. This technique can achieve a high level of quality and richness in the print, and produce a furniture print which is large and bold enough to be framed and hung effectively in a room. Mezzotint is often combined with other intaglio techniques, usually etching and engraving, including stipple engraving. The process was especially widely used in England from the eighteenth century, and in France was called ''la manière anglais'' (“the English manner”). Until the 20th century it has mostly been used for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacob Christoph Le Blon
Jacob Christoph Le Blon, or Jakob Christoffel Le Blon, (2 May 1667 – 16 May 1741) was a painter and engraver from Frankfurt who invented a halftone color printing system with three and four copper dyes using an RYB color model, which served as the foundation for the modern CMYK system.O. M. Lilien (1985). Jacob Christoph Le Blon, 1667-1741: Inventor of three- and four colour printing. Stuttgart: Hiersemann. He used the mezzotint method to engrave three or four copper plates (one each per printing ink) to make prints of paintings and portraits with a wide range of colors. Biography On his father's side Le Blon descended from Huguenots who fled France in 1576, settling in Frankfurt. He belonged to a family of printers and booksellers who focused on travel books. His father, Christophe Le Blon, was an engraver and bookseller in Frankfurt am Main Frankfurt am Main () is the most populous city in the States of Germany, German state of Hesse.

Franciscus Aguilonius
Franciscus is a Latin given name, originally an epithet meaning "the Frank, the Frenchman". It was applied to Saint Francis of Assisi (1181/82–1226). Francis had been baptized Giovanni (John); his father was Italian and his mother Provençale ( at the time not considered French); his father was on business in France when he was born, and when he returned to Assisi, he began to call his son by the nickname ''Francesco'', in the opinion of G. K. Chesterton possibly because out of a general enthusiasm for all things French, or because of his commercial success in France.Chesterton, Gilbert Keith (1924). "St. Francis of Assisi" (14 ed.). Garden City, New York: Image Books. p. 158. After the canonization of Saint Francis of Assisi in 1228, the custom of naming children after saints led to the popularization of ''Franciscus'' as a given name. In the vernaculars of western Europe, the name diversified into the forms Francesco (Italian), Francisco (Spanish and Portuguese), Franc ...

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 ...

RGB Color Model
The RGB color model is an additive color, additive color model in which the red, green, and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue. The main purpose of the RGB color model is for the sensing, representation, and display of images in electronic systems, such as televisions and computers, though it has also been used in conventional photography and Light-emitting diode#RGB systems, colored lighting. Before the electronic age, the RGB color model already had a solid theory behind it, based in Trichromacy, human perception of colors. RGB is a ''device-dependent'' color model: different devices detect or reproduce a given RGB value differently, since the color elements (such as phosphors or dyes) and their response to the individual red, green, and blue levels vary from manufacturer to manufacturer, or even in the ...

Tints And Shades
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. A tone is produced either by mixing a color with gray, or by both tinting and shading. Mixing a color with any neutral color (black, gray, and white) reduces the chroma, or colorfulness, while the perceived hue can be affected slightly (see Abney effect and Bezold-Brücke shift). 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 generalized to refer to any lighter or darker variation of a color (e.g. " tinted windows"). When mi ...
