The impression of white light can be created by mixing appropriate intensities of the primary colors of light — red, green and blue — a process called additive mixing, but the illumination provided by this technique has significant differences from that produced by incandescence. Light, or visible light, is Electromagnetic radiation of a Wavelength that is visible to the Human eye (about 400–700 Primary colors are sets of Colors that can be combined to make a useful range ( Gamut) of colors Red is any of a number of similar Colors evoked by light consisting predominantly of the longest wavelengths of Light discernible by the human eye in the wavelength Green is a Color, the perception of which is evoked by light having a spectrum dominated by energy with a Wavelength of roughly 520–570- nm.

In nature, white results when transparent fibers, particles, or droplets are in a transparent matrix of a substantially different refractive index. In Optics, transparency (also called pellucidity) is the Material property of allowing Fiber or fibre is a class of Materials that are continuous filaments or are in discrete elongated pieces similar to lengths of thread. A drop or droplet is a small volume of Liquid, bounded completely or almost completely by Free surfaces Surface tension Examples include classic "white" substances such as sugar, foam, pure sand or snow, cotton, clouds, and milk. Sugar is a class of edible Crystalline substances mainly Sucrose, Lactose, and Fructose. The most general definition of foam is a substance that is formed by trapping many gas Bubbles in a Liquid or Solid. Sand is a naturally occurring Granular material composed of finely divided rock and Mineral particles "Snowfall" redirects here For other uses see Snow (disambiguation or Snowfall (disambiguation. Cotton is a soft staple Fibre that grows around the seeds of the cotton plant ( Gossypium sp A cloud is a visible mass of droplets or frozen crystals floating in the atmosphere above the surface of the Earth or another Planetary body Milk is an opaque white liquid produced by the Mammary glands of female Mammals (including Monotremes. Crystal boundaries and imperfections can also make otherwise transparent materials white, as in the milky quartz or the microcrystalline structure of a seashell. In Materials science, a crystal is a Solid in which the constituent Atoms Molecules or Ions are packed in a regularly ordered repeating Quartz (from German) is the most abundant Mineral in the Earth 's Continental crust (although Feldspar is more common in A seashell, also known as a sea shell, is the Common name for a hard protective outer layer a shell or in some cases a " test " that was created This is also true for artificial paints and pigments, where white results when finely divided transparent material of a high refractive index is suspended in a contrasting binder. Paint is any Liquid, liquifiable or mastic composition which after application to a substrate in a thin layer is converted to an opaque Solid For the drug referred to as "pigment" see Black tar heroin. Typically paints contain calcium carbonate and/or synthetic rutile with no other pigments if a white color is desired. Calcium carbonate is a Chemical compound with the Chemical formula Ca[[Carbon C]] O 3 Rutile is a Mineral composed primarily of Titanium dioxide, Ti[[oxygen O]]2

Etymology and definitions

The word white comes from the Common Germanic hwitaz though the Old English word hwīt. Proto-Germanic, or Common Germanic, is the hypothetical common ancestor ( Proto-language) of all the Germanic languages such as modern English [2] The word designates the perception of light containing equal amounts of all wavelengths in the visible spectrum.

Shade

Paint

In painting, white can be crafted by reflecting ambient light from a white pigment, although the ambient light must be white light, or else the white pigment will appear the color of the light. Painting (pān'tīng in Art, is the practice of applying Color to a Surface (support base such as e Reflection is the change in direction of a Wave front at an interface between two different media so that the wave front returns into the medium from which For the drug referred to as "pigment" see Black tar heroin. White when mixed with black produces gray. To art students, the use of white can present particular problems, and there is at least one training course specializing in the use of white in art. In watercolor painting, white areas are the absence of paint on the paper. Watercolor ( US) or Watercolour ( UK) (and "aquarelle" in French is a Painting method There are also speculations about the use of white and other colors.

Until Newton's work became accepted, most scientists believed that white was the fundamental color of light; and that other colors were formed only by adding something to light. Sir Isaac Newton, FRS (ˈnjuːtən 4 January 1643 31 March 1727) Biography Early years See also Isaac Newton's early life and achievements Science (from the Latin scientia, meaning " Knowledge " or "knowing" is the effort to discover, and increase human understanding Newton demonstrated this was not true by passing white light through a prism, then through another prism. In Optics, a prism is a transparent optical element with flat polished surfaces that refract Light. If the colors were added by the prism, the second prism should have added further colors to the single-colored beam. Since the single-colored beam remained a single color, Newton concluded that the prism merely separated the colors already present in the light. In Optics, dispersion is the phenomenon in which the Phase velocity of a wave depends on its frequency White light is the effect of combining the visible colors of light in equal proportions.

In the science of lighting, there is a continuum of colors of light that can be called "white". Continuum theories or models explain variation as involving a gradual quantitative transition without abrupt changes or discontinuities One set of colors that deserves this description is the color emitted via the process called incandescence, by a black body at various relatively-high temperatures. Incandescence is the emission of Light (visible Electromagnetic radiation) from a hot body due to its temperature In Physics, a black body is an object that absorbs all light that falls on it For example, the color of a black body at a temperature of 2848 kelvins matches that produced by domestic incandescent light bulbs. The kelvin (symbol K) is a unit increment of Temperature and is one of the seven SI base units The Kelvin scale is a thermodynamic The incandescent light bulb, incandescent lamp or incandescent light globe is a source of electric Light that works by Incandescence, (a general It is said that "the color temperature of such a light bulb is 2848 K". Color temperature is a characteristic of Visible light that has important applications in lighting photography videography publishing and other fields The white light used in theatre illumination has a color temperature of about 3200 K. Theatre (or theater, see spelling differences) is the branch of the Performing arts defined by Bernard Beckerman as what "occurs when one Daylight can vary from a cool red up to a bluish 25,000 K. Not all black body radiation can be considered white light: the background radiation of the universe, to name an extreme example, is only a few kelvins and is quite invisible. Background radiation is the Ionizing radiation emitted from a variety of natural and artificial Radiation sources The Universe is defined as everything that Physically Exists: the entirety of Space and Time, all forms of Matter, Energy

Objects

While the color of a light source can be reasonably measured by its correlated color temperature, a different approach is required for objects since different samples may appear white without a reference. Color temperature is a characteristic of Visible light that has important applications in lighting photography videography publishing and other fields Thus, assessment of whiteness requires a comparison. In Colorimetry, whiteness is the degree to which a surface is white The International Commission on Illumination (CIE) prescribes one such method. Established in 1913 and based in Vienna, Austria, the International Commission on Illumination (usually known as the CIE for its French name Commission

Computer color temperature

Computer displays often have a color temperature control, allowing the user to select the color temperature (usually from a small set of fixed values) of the light emitted when the computer produces the electrical signal corresponding to "white". A visual display unit, often called simply a monitor or display, is a piece of Electrical equipment which displays images generated from the Video The RGB coordinates of white are (255, 255, 255).
