Shades of blue
Varieties of the color blue may differ in hue, chroma (also called saturation, intensity, or colorfulness), or lightness (or value, tone, or brightness), or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a blue or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below. In this section, the term tint is used in its technical sense as used in color theory, meaning a blueish color mixed with white or light gray. Baby blue is known as one of the pastel colors. With a hue code of 199, this color is a tone of azure.
Violet (color)
Violet is the color at the end of the visible spectrum of light between blue and the invisible ultraviolet. Violet color has a dominant wavelength of approximately 380-450 nanometers. Light with a shorter wavelength than violet but longer than X-rays and gamma rays is called ultraviolet. In the color wheel historically used by painters, it is located between blue and purple. On the screens of computer monitors and television sets, a color which looks similar to violet is made, with the RGB color model, by mixing red and blue light, with the blue twice as bright as the red. This is not true violet, since it is composed of multiple longer wavelengths rather than a single wavelength shorter than that of blue light.
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.
Sapphire
Sapphire is a gemstone, a variety of the mineral corundum, an aluminium oxide (). It is typically blue, but natural "fancy" sapphires also occur in yellow, purple, orange, and green colors; "parti sapphires" show two or more colors. The only color which sapphire cannot be is red – as red colored corundum is called ruby, another corundum variety. Pink colored corundum may be either classified as ruby or sapphire depending on locale. This variety in color is due to trace amounts of elements such as iron, titanium, chromium, copper, or magnesium. Commonly, natural sapphires are cut and polished into gemstones and worn in jewelry.
Red
Red is the colour at the end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy. The red sky at sunset results from Rayleigh scattering, while the red color of the Grand Canyon and other geological features is caused by hematite or red ochre, both forms of iron oxide.
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.
Shades of violet
There are numerous variations of the color violet, a sampling of which are shown below. Although pure spectrum violet is outside the color gamut of the RGB color space, the three colors displayed below are rough approximations of the range of colors of actual spectral violet, although the accuracy of the approximation can vary depending on the individual's color vision, and on the color rendition of one's computer monitor. The tertiary color on the HSV color wheel (also known as the ) precisely halfway between blue and magenta is called color wheel violet. This tone of violet—an approximation of the color violet at about 417 nanometers as plotted on the CIE chromaticity diagram—is shown at right.

It's All Over Now, Baby Blue
"It's All Over Now, Baby Blue" is a song written and performed by Bob Dylan and featured on his "Bringing It All Back Home" album, released on March 22, 1965 by Columbia Records ("see" 1965 in music). The song was recorded on January 15, 1965 with Dylan's acoustic guitar and harmonica and William E. Lee's bass guitar the only instrumentation. The lyrics were heavily influenced by Symbolist poetry and bid farewell to the titular "Baby Blue." There has been much speculation about the real life identity of "Baby Blue", with possibilites including Joan Baez, David Blue, Paul Clayton, Dylan's folk music audience, and even Dylan himself.
Baby blue
Baby blue is a pale tint of azure, one of the pastel colors. The first recorded use of "baby blue" as a color name in English was in 1892. Bubbles is a pale tint of baby blue. The color name "bubbles" has been in use since 2001 when the Xona.com Color List was first promulgated. Beau blue is a light tone of baby blue. The source of this color is the color that is called "beau blue" in the "Plochere Color System", a color system formulated in 1948 that is widely used by interior designers. Baby blue eyes is a rich tone of baby blue.

List of Care Bear characters
The Care Bears are a group of characters created by the U.S. greeting card company American Greetings in 1981. The title characters originally appeared in card artwork by Elena Kucharik, before branching out into various media and merchandise. The franchise launched in 1982 with ten title characters, and in 1984 added several more characters known as the Care Bear Cousins. Each of the Care Bears and Care Bear Cousins has a "tummy symbol" — a picture or pattern that indicates the role or specialty of the character bearing it. Beginning with "", "tummy symbols" are sometimes referred to as "belly badges."
Azure (color)
Azure ( ) is a variation of blue that is often described as the color of the sky on a clear day. On the , "azure" (color #007FFF) is defined as the color at 210 degrees, i.e., the hue halfway between blue and cyan. In the RGB color model, used to create all the colors on a television or computer screen, azure is created by adding a little green light to blue light. The complementary color of azure is orange. In the X11 color system which became a standard for early web colors, azure is depicted as a pale cyan. The color azure ultimately takes its name from the intense blue mineral lapis lazuli. '

Baby Blue (rapper)
Baby Blue is an English rapper and singer from London, England. She is known for her work with singer Estelle and collaborations with John Legend, Madness, Sway, Shystie, Ms. Dynamite and Lady Sovereign. Baby Blue has a sound that fuses hip hop with grime, R&B and soul. Baby Blue started rapping while at school and eventually recorded a track called 'I Woulda', which was inspired by her cousin's gang-related death in the US. The track received heavy rotation and was the start of Baby Blue's career as a recording artist. When she was 19 she sent her music to UK artist Estelle, who immediately invited Baby Blue to New York City to record the song 'Hey Girl' featuring John Legend, as well as 'Don't Talk', another track for Estelle's début album The 18th Day, which was certified gold in the UK and she was also featured rapping in the video for the hit top 20 track 1980.

The name of the web color is written as "lightpink" (no space) in HTML for computer display. Although this color is called "light pink", as can be ascertained by inspecting its hex code, it is actually a slightly deeper, not a lighter, tint of pink than the color pink itself. A more accurate name for it in terms of traditional color nomenclature would therefore be "medium light pink". At right is displayed the web color hot pink.

I heard that the sky and ocean are not actually blue, they just appear as such due to an optical effect.

Thats true, because the eye just perceives blue when seeing a certain wavelength of about 450 nanometres.
The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres.

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.

Planck's law
Planck's law describes the spectral density of electromagnetic radiation emitted by a black body in thermal equilibrium at a given temperature "T". The law is named after Max Planck, who proposed it in 1900. It is a pioneering result of modern physics and quantum theory. The spectral radiance of a body, , describes the amount of energy it gives off as radiation of different frequencies. It is measured in terms of the power emitted per unit area of the body, per unit solid angle that the radiation is measured over, per unit frequency. Planck showed that the spectral radiance of a body for frequency at absolute temperature is given by  where is the Boltzmann constant, is the Planck constant, and is the speed of light in the medium, whether material or vacuum.
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.
K3 (band)
K3 is a Belgian-Dutch girl group with a Dutch repertoire, whose current line-up is composed of Hanne Verbruggen, Marthe De Pillecyn and Klaasje Meijer, mainly aimed at pre-adolescent children. The name of the group is derived from first letters of the three original members' first names: Karen Damen, Kristel Verbeke and Kathleen Aerts. Kathleen Aerts left the group in 2009. Josje Huisman was chosen as K3's new member on October 3, 2009. Their music is produced by production company Studio 100 and is written by Miguel Wiels, Alain Vande Putte and Peter Gillis. K3 was founded by Niels William. The band became famous without any airplay from the regular music television channels like MTV, instead marketing directly to children via children- and cartoon-channels.
Optical telescope
An optical telescope is a telescope that gathers and focuses light, mainly from the visible part of the electromagnetic spectrum, to create a magnified image for direct view, or to make a photograph, or to collect data through electronic image sensors. There are three primary types of optical telescope:  A telescope's light gathering power and ability to resolve small detail is directly related to the diameter (or aperture) of its objective (the primary lens or mirror that collects and focuses the light). The larger the objective, the more light the telescope collects and the finer detail it resolves.
Color
Color (American English) or colour (Commonwealth English) is the characteristic of human visual perception described through color "categories", with names such as red, blue, yellow, green, orange, or purple. This perception of color derives from the stimulation of cone cells in the human eye by electromagnetic radiation in the spectrum of light. Color categories and physical specifications of color are associated with objects through the wavelength of the light that is reflected from them. This reflection is governed by the object's physical properties such as light absorption, emission spectra, etc.

John Tyndall (politician)
John Hutchyns Tyndall (14 July 193419 July 2005) was a British fascist political activist. A leading member of various small neo-Nazi groups during the late 1950s and 1960s, he was chairman of the National Front from 1972 to 1974 and again from 1975 to 1980, and then chairman of the British National Party from 1982 to 1999. He unsuccessfully stood for election to the House of Commons and European Parliament on several occasions. Born in Devon and educated in Kent, Tyndall undertook national service prior to embracing the extreme-right. In the mid-1950s, he joined the League of Empire Loyalists (LEL) and came under the influence of its leader, Arthur Chesterton.
British National Party
The British National Party (BNP) is a far-right and fascist political party in the United Kingdom. It is headquartered in Wigton, Cumbria, and its current leader is Adam Walker. A minor party, it currently has one councillor in UK local government. During its heyday in the 2000s, it had over fifty seats in local government, one seat on the London Assembly, and two Members of the European Parliament. The BNP was formed in 1982 by John Tyndall and other former members of the National Front (NF). By Tyndall's admission, it remained ideologically identical to the NF, and took its name from that of a defunct 1960s party.
John Tyndall
John Tyndall FRS (2 August 1820 – 4 December 1893) was a prominent 19th-century Irish physicist. His initial scientific fame arose in the 1850s from his study of diamagnetism. Later he made discoveries in the realms of infrared radiation and the physical properties of air. Tyndall also published more than a dozen science books which brought state-of-the-art 19th century experimental physics to a wide audience. From 1853 to 1887 he was professor of physics at the Royal Institution of Great Britain in London. Tyndall was born in Leighlinbridge, County Carlow, Ireland. His father was a local police constable, descended from Gloucestershire emigrants who settled in southeast Ireland around 1670.
National Front (UK)
The National Front (NF) is a far-right and fascist political party in the United Kingdom. It is headquartered in Kingston upon Hull and is currently led by David MacDonald. A minor party, it has no elected representatives at any level of UK government. During its heyday in the 1970s, it had a small number of local councillors, although it has never secured a seat in the British Parliament. The NF was founded by A. K. Chesterton in 1967 as a merger between his League of Empire Loyalists and the British National Party. It was soon joined by the Greater Britain Movement, whose leader John Tyndall became the Front's chairman in 1972.
History of the National Front (UK)
The history of the National Front, a far-right political party in the United Kingdom, began in 1967, when it was founded by A. K. Chesterton. The National Front was established as a coalition of small extreme-right groups which were active on the fringes of British politics during the 1960s. These were the British National Party (BNP), the League of Empire Loyalists (LEL), the Racial Preservation Society (RPS), the Greater Britain Movement (GBM), and some branches of the Anglo-Rhodesian Society. Many in these parties were experiencing growing frustration at their powerlessness. The LEL's leader A. K. Chesterton was concerned that the Monday Club, a newly established group on the hard right of the Conservative Party, would take some of the support away from his LEL.
Tyndall
Tyndall (the original spelling, also Tyndale, "Tindol",Tyndal, Tindall, Tindal, Tindale, Tindle, Tindell, Tindill, and Tindel) is the name of an English family taken from the land they held as tenants in chief of the Kings of England and Scotland in the 11th, 12th and 13th centuries: Tynedale, or the valley of the Tyne, in Northumberland. With origins in the ancient Anglo Saxon nobility of Northumbria, the Royal Scottish House of Dunkeld and the Anglo-Norman nobility, they have contributed courtiers, judges, writers, historians, sailors, airmen, scientists and philosophers to the history of England, Ireland and the new world.
