Color

Color (American English) or colour (Commonwealth English) is the visual perceptual property corresponding in humans to the categories called red, blue, yellow, etc. Color derives from the spectrum of light (distribution of light power versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of color are also 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.

The science of color is sometimes called chromatics, colorimetry, or simply color science. It includes the perception of color by the human eye and brain, the origin of color in materials, color theory in art, and the physics of electromagnetic radiation in the visible range (that is, what we commonly refer to simply as light).

Tincture (heraldry)

In heraldry, tinctures are the colours used to emblazon a coat of arms. These can be divided into several categories including light tinctures called metals, dark tinctures called colours, nonstandard colours called stains, patterns called furs, and "proper". A charge described as proper (also sometimes termed "natural") is coloured as it would be found in nature.

Use of tinctures

One of the few fundamental rules of heraldry is that metals must not be placed upon other metals and colours must not be placed upon other colours, while furs and proper can sometimes be placed upon either or both. This is referred to as the rule of tincture.

Nonstandard colours called stains were introduced in the late Middle Ages, but have largely been shunned as contrary to the heraldic spirit of bold images and bright, contrasting colours. A peculiar fad of the Renaissance sought to couple each tincture with an associated planet, gemstone, flower, astrological sign, etc., but this practice was soon abandoned and is now regarded as wildly divergent from the science of heraldry. The 19th century saw the rise of "landscape heraldry" and extensive use of charges tinctured "proper", especially in augmentations (and more often in German heraldry than English), but this practice too has been deprecated as essentially unheraldic.

Timbre

In music, timbre (/ˈtæmbər/ TAM-bər or /ˈtɪmbər/ TIM-bər) also known as tone color or tone quality from psychoacoustics, is the quality of a musical note, sound, or tone that distinguishes different types of sound production, such as voices and musical instruments, string instruments, wind instruments, and percussion instruments. The physical characteristics of sound that determine the perception of timbre include spectrum and envelope.

In simple terms, timbre is what makes a particular musical sound different from another, even when they have the same pitch and loudness. For instance, it is the difference between a guitar and a piano playing the same note at the same loudness. Experienced musicians are able to distinguish between different instruments of the same type based on their varied timbres, even if those instruments are playing notes at the same pitch and loudness.

Synonyms

Tone quality and color are synonyms for timbre, as well as the "texture attributed to a single instrument". Hermann von Helmholtz used the German Klangfarbe (tone color), and John Tyndall proposed an English translation, clangtint, but both terms were disapproved of by Alexander Ellis, who also discredits register and color for their pre-existing English meanings (Erickson 1975, 7).

Dada

Dada (/ˈdɑːdɑː/) or Dadaism was an art movement of the European avant-garde in the early 20th century. Dada in Zürich, Switzerland, began in 1916 at Cabaret Voltaire, spreading to Berlin shortly thereafter, but the height of New York Dada was the year before, in 1915. The term anti-art, a precursor to Dada, was coined by Marcel Duchamp around 1913 when he created his first readymades. Dada, in addition to being anti-war, had political affinities with the radical left and was also anti-bourgeois.

At least two works qualified as pre-Dadaist, a posteriori, had already sensitized the public and artists alike: Ubu Roi (1896) by Alfred Jarry, and the ballet Parade (1916–17) by Erik Satie. The roots of Dada lay in pre-war avant-garde. Cubism and the development of collage, combined with Wassily Kandinsky’s theoretical writings and abstraction, detached the movement from the constraints of reality and convention. The influence of French poets and the writings of German Expressionists liberated Dada from the tight correlation between words and meaning. Avant-garde circles outside France knew of pre-war Parisian developments. They had seen (or participated in) Cubist exhibitions held at Galería Dalmau, Barcelona (1912), Galerie Der Sturm in Berlin (1912), the Armory show in New York (1913), SVU Mánes in Prague (1914), several Jack of Diamonds exhibitions in Moscow and at De Moderne Kunstkring, Amsterdam (between 1911 and 1915). Futurism developed in response to the work of various artists. Dada subsequently combined these approaches.

Dada (2000 film)

Dada is an action Hindi film made in 2000. A revenge drama, with Mithun in the lead role.

Plot
