Black is the color of objects that do not emit or reflect light in any part of the visible spectrum; they absorb all such frequencies of light. Although black is sometimes described as an "achromatic", or hueless, color, in practice it can be considered a color, as in expressions like "black cat" or "black paint".

Etymology

The word black comes from Old English blæc ("black, dark", also, "ink"), from Proto-Germanic *blakkaz ("burned"), from Proto-Indo-European *bhleg- ("to burn, gleam, shine, flash"), from base *bhel- ("to shine"), related to Old Saxon blak ("ink"), Old High German blah ("black"), Old Norse blakkr ("dark"), Dutch blaken ("to burn"), and Swedish bläck ("ink"). More distant cognates include Latin flagrare ("to blaze, glow, burn"), and Ancient Greek phlegein ("to burn, scorch"). Black supplanted the wonted Old English word sweart ("black, dark"), which survives as swart, swarth, and swarthy (compare German schwarz "black").

Color or light in science

[[File:|thumb|Nighttime]] Black can be defined as the visual impression experienced when no visible light reaches the eye. (This makes a contrast with whiteness, the impression of any combination of colors of light that equally stimulates all three types of color-sensitive visual receptors.)

Pigments that absorb light rather than reflect it back to the eye "look black". A black pigment can, however, result from a combination of several pigments that collectively absorb all colors. If appropriate proportions of three primary pigments are mixed, the result reflects so little light as to be called "black".

This provides two superficially opposite but actually complementary descriptions of black. Black is the lack of all colors of light, or an exhaustive combination of multiple colors of pigment. See also Primary colors

In physics, a black body is a perfect absorber of light, but, by a thermodinamic rule, it is also the best emitter. Thus, the best radiative cooling, out of sunlight, is by using black paint, though it is important that it be black (a nearly perfect absorber) in the infrared as well.

In elementary science, far Ultraviolet light is called "black light" because, unseen, it causes many minerals and other substances to fluoresce.

On January 16, 2008, researchers from Troy, New York’s Rensselaer Polytechnic Institute announced the creation of the darkest material on the planet. The material, which reflects only .045 percent of light, was created from carbon nanotubes stood on end. This is 1/30 of the light reflected by the current standard for blackness, and one third the light reflected by the previous record holder for darkest substance.[1]

Absorption of light

A material is said to be black if most incoming light is absorbed equally in the material. Light (electromagnetic radiation in the visible spectrum) interacts with the atoms and molecules, which causes the energy of the light to be converted in to other forms of energy, usually heat. This means that black surfaces can act as thermal collectors, absorbing light and generating heat(see Solar thermal collector).

Absorption of light is contrasted by transmission, reflection and diffusion, where the light is only redirected, causing objects to appear transparent, reflective or white respectively.

  • The Lützow Free Corps, composed of volunteer German students and academics fighting against Napoleon in 1813, could not afford to make special uniforms and therefore adopted black, as the only color that could be used to dye their civilian clothing without the original color showing. As these volunteers were greatly praised and glorified by later revolutionaries, their choice of the black color might have influenced its later connotations.
  • Black is used for anarchist symbolism, sometimes split in diagonal with other colors to show alignment with another political philosophy. The plain black flag is explained in various ways, sometimes as an anti-flag or a non-flag. Wearing black clothing is also sometimes an anarchist tactic during demonstrations, with a practical benefit of not attracting attention and making later identification of a subject difficult. This strategy is referred to as a black bloc.
  • In Portuguese politics, black (and red) is the party color of the Left Bloc.

  • In Nazi Germany, the blackshirts was a nickname for the SS, as opposed to the brownshirts, the SA.
  • The black triangle was used by the Nazis to designate "asocial" people (homeless and Roma, for example); later the symbol was adopted by lesbian culture.
