Grow light
A grow light or plant light is an artificial light source, generally an electric light, designed to stimulate plant growth by emitting a light appropriate for photosynthesis. Grow lights are used in applications where there is either no naturally occurring light, or where supplemental light is required. For example, in the winter months when the available hours of daylight may be insufficient for the desired plant growth, lights are used to extend the time the plants receive light. If plants do not receive enough light, they will grow long and spindly. Grow lights either attempt to provide a light spectrum similar to that of the sun, or to provide a spectrum that is more tailored to the needs of the plants being cultivated.
Fluorescence
Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore lower energy, than the absorbed radiation. The most striking example of fluorescence occurs when the absorbed radiation is in the ultraviolet region of the spectrum, and thus invisible to the human eye, while the emitted light is in the visible region, which gives the fluorescent substance a distinct color that can only be seen when exposed to UV light. Fluorescent materials cease to glow immediately when the radiation source stops, unlike phosphorescence, where they continue to emit light for some time after.
Metamaterial cloaking
Metamaterial cloaking is the usage of metamaterials in an invisibility cloak. This is accomplished by manipulating the paths traversed by light through a novel optical material. Metamaterials direct and control the propagation and transmission of specified parts of the light spectrum and demonstrate the potential to render an object seemingly invisible. Metamaterial cloaking, based on transformation optics, describes the process of shielding something from view by controlling electromagnetic radiation. Objects in the defined location are still present, but incident waves are guided around them without being affected by the object itself.
Infrared photography
In infrared photography, the film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging. Wavelengths used for photography range from about 700 nm to about 900 nm. Film is usually sensitive to visible light too, so an infrared-passing filter is used; this lets infrared (IR) light pass through to the camera, but blocks all or most of the visible light spectrum (the filter thus looks black or deep red). ("Infrared filter" may refer either to this type of filter or to one that blocks infrared but passes other wavelengths.)
Light-emitting diode
A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p–n junction diode that emits light when activated. When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor. LEDs are typically small (less than 1 mm) and integrated optical components may be used to shape the radiation pattern. Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared light.
Ultraviolet
Ultraviolet (UV) is an electromagnetic radiation with a wavelength from 10 nm to 400 nm, shorter than that of visible light but longer than X-rays. UV radiation constitutes about 10% of the total light output of the Sun, and is thus present in sunlight. It is also produced by electric arcs and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. Although it's not considered an ionizing radiation because its photons lack the energy to ionize atoms, long-wavelength ultraviolet radiation can cause chemical reactions and causes many substances to glow or fluoresce. Consequently, the chemical and biological effects of UV are greater than simple heating effects, and many practical applications of UV radiation derive from its interactions with organic molecules.
Purple
Purple is a color intermediate between blue and red. It is similar to violet, but unlike violet, which is a spectral color with its own wavelength on the visible spectrum of light, purple is a composite color made by combining red and blue. According to surveys in Europe and the U.S., purple is the color most often associated with royalty, magic, mystery and piety. When combined with pink, it is associated with eroticism, femininity and seduction. Purple was the color worn by Roman magistrates; it became the imperial color worn by the rulers of the Byzantine Empire and the Holy Roman Empire, and later by Roman Catholic bishops.

Yes! I like blue a lot as well. Do you have a favorite shade of blue?
0_Wizard
I like the azure shade of blue because it contains some green, I like the way it looks really.
Most blues contain a slight mixture of other colors; azure contains some green, while ultramarine contains some violet.

Blue–green distinction in language
Many languages do not distinguish between what in English are described as "blue" and "green" and instead use a cover term spanning both. To describe this English lexical gap, linguists use the portmanteau word "grue", from "green" and "blue", which the philosopher Nelson Goodman coined in his 1955 "Fact, Fiction, and Forecast" to illustrate the "new riddle of induction". The exact definition of "blue" and "green" may be complicated by the speakers not primarily distinguishing the hue, but using terms that describe other color components such as saturation and luminosity, or other properties of the object being described.
Characters of The Order of the Stick
This is a list of characters from the webcomic "The Order of the Stick" (OOTS). Celebrating and satirizing tabletop role-playing games and medieval fantasy, this tale of the eponymous fellowship of adventuring heroes is written and illustrated by Rich Burlew in a stick-figure style. Taking place in a magical world that loosely operates by the rules of the 3.5 edition "Dungeons & Dragons" (D&D), the comic follows the sometimes-farcical exploits of six adventurers as they strive to save the world from an evil lich. Much of the comic's humor stems from these characters either being aware of the game rules that affect their lives or having anachronistic knowledge of modern culture, which in turn is often used by the author to parody various aspects of role-playing games and fantasy fiction.
List of Ben 10 aliens
This is a list of aliens on Cartoon Network's "Ben 10 franchise". Voiced by:  Heatblast is a Pyronite from the star Pyros. He appears as a magma-based lifeform whose body is composed of a bright inner magma body covered by a reddish-brown charcoal-like crust. Heatblast is essentially "living magma", thus everything he touches either melts or catches fire. In the original series, he is the tenth alien in the Omnitrix. Heatblast is Ben's first transformation, accidentally activated and started a wildfire in the pilot episode of the original series, "And Then There Were 10" when Ben was trying to remove the Omnitrix immediately after it first attached to him.
List of Donald Duck universe characters
This list of Donald Duck universe characters focuses on Disney cartoon characters who typically appear with Donald Duck and Scrooge McDuck, but are not related to them. For relatives of Donald and Scrooge, see Duck family (Disney) or Clan McDuck. For characters exclusive to the "DuckTales" franchise, see List of "DuckTales" characters. Ducks are the most common type of named characters in the Donald Duck universe. Like Donald, they appear as white American Pekin ducks. This section contains a list of characters with the surname "Duck" who are not related to Donald. As Don Rosa explained, "Duck" is an common name in Duckburg (just as "Smith" or "Jones" are common in the real-life United States) and does not necessarily identify a blood relation of Donald.
Blue
Blue is one of the three primary colours of pigments in painting and traditional colour theory, as well as in the RGB colour model. It lies between violet and green on the spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colors; azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called Tyndall scattering explains blue eyes.
Thirteen Cents
Thirteen Cents is the debut novel of South African author K. Sello Duiker. It was published in 2000 to critical acclaim and immediate success in South Africa and abroad, winning the 2002 Commonwealth Writers Prize for Best First Book, Africa. The first edition of "Thirteen Cents" outside South Africa was published by Ohio University Press in 2013 as part of the Modern African Writing series with an introduction by Professor Shaun Viljoen. The novel is set in post-apartheid South Africa and depicts the brutal reality of South African street children. As a crime novel and bildungsroman, it follows the twelve-year-old orphan Azure and his efforts to survive on the streets of Cape Town amidst an underworld of gangsters, drug use, violence, and prostitution.
List of Forgotten Realms characters
This is a list of fictional characters from the "Forgotten Realms" campaign setting for the "Dungeons & Dragons" fantasy role-playing game. Most of these characters have appeared in the multiple series of novels set in the "Forgotten Realms". Many have some magical abilities. Aballister Bonaduce is the nemesis of his son Cadderly Bonaduce, the main character of R.A. Salvatore's The Cleric Quintet. Calculating, cold, and merciless, Aballister is determined to complete his conquest of the region. Guided by the goddess Talona, Mistress of Poison, Aballister creates The Chaos Curse and unleashes it upon The Edificant Library, home of Cadderly and his friends.

Mie scattering
The Mie solution to Maxwell's equations (also known as the Lorenz–Mie solution, the Lorenz–Mie–Debye solution or Mie scattering) describes the scattering of an electromagnetic plane wave by a homogeneous sphere. The solution takes the form of an infinite series of spherical multipole partial waves. It is named after Gustav Mie. The term "Mie solution" is also used for solutions of Maxwell's equations for scattering by stratified spheres or by infinite cylinders, or other geometries where one can write separate equations for the radial and angular dependence of solutions. The term "Mie theory" is sometimes used for this collection of solutions and methods; it does not refer to an independent physical theory or law.
Rayleigh scattering
Rayleigh scattering (pronounced ), named after the British physicist Lord Rayleigh (John William Strutt), is the (dominantly) elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation. Rayleigh scattering does not change the state of material and is, hence, a parametric process. The particles may be individual atoms or molecules. It can occur when light travels through transparent solids and liquids, but is most prominently seen in gases. Rayleigh scattering results from the electric polarizability of the particles. The oscillating electric field of a light wave acts on the charges within a particle, causing them to move at the same frequency.
Eye color
Eye color is a polygenic phenotypic character determined by two distinct factors: the pigmentation of the eye's iris and the frequency-dependence of the scattering of light by the turbid medium in the stroma of the iris. In humans, the pigmentation of the iris varies from light brown to black, depending on the concentration of melanin in the iris pigment epithelium (located on the back of the iris), the melanin content within the iris stroma (located at the front of the iris), and the cellular density of the stroma. The appearance of blue and green, as well as hazel eyes, results from the Tyndall scattering of light in the stroma, a phenomenon similar to that which accounts for the blueness of the sky called Rayleigh scattering.
Scattering
Scattering is a general physical process where some forms of radiation, such as light, sound, or moving particles, are forced to deviate from a straight trajectory by one or more paths due to localized non-uniformities in the medium through which they pass. In conventional use, this also includes deviation of reflected radiation from the angle predicted by the law of reflection. Reflections that undergo scattering are often called "diffuse reflections" and unscattered reflections are called "specular" (mirror-like) reflections. Scattering may also refer to particle-particle collisions between molecules, atoms, electrons, photons and other particles.
Skyglow
Skyglow (or sky glow) is the diffuse luminance of the night sky, apart from discrete light sources such as the Moon and visible individual stars. It is a commonly noticed aspect of light pollution. While usually referring to sky luminance arising from artificial lighting, skyglow may also involve any nighttime sources of diffuse light, including natural ones like the zodiacal light, starlight, and airglow. In the context of light pollution, skyglow arises from the use of artificial light sources, including electrical (or rarely gas) lighting used for illumination and advertisement, and from gas flares.

Atmospheric optics
Atmospheric optics deals with how the unique optical properties of Earth's atmosphere cause a wide range of spectacular optical phenomena. The blue color of the sky is a direct result of Rayleigh scattering, which redirects higher frequency (blue) sunlight back into the field of view of the observer. Because blue light is scattered more easily than red light, the Sun takes on a reddish hue when it is observed through a thick atmosphere, as during a sunrise or sunset. Additional particulate matter in the sky can scatter different colors at different angles, creating colorful, glowing skies at dusk and dawn.

Neat! I guess Rayleigh scattering causes the sky to be blue and the sun effects those colors at dusk and dawn
