Color theory
In the visual arts, color theory or colour theory is a body of practical guidance to color mixing and the visual effects of a specific color combination. There are also definitions (or categories) of colors based on the color wheel: primary color, secondary color and tertiary color. Although color theory principles first appeared in the writings of Leone Battista Alberti (c.1435) and the notebooks of Leonardo da Vinci (c.1490), a tradition of "colory theory" began in the 18th century, initially within a partisan controversy over Isaac Newton's theory of color ("Opticks", 1704) and the nature of primary colors.
Complementary colors
Complementary colors are pairs of colors which, when combined, cancel each other out. This means that when combined, they produce a gray-scale color like white or black. When placed next to each other, they create the strongest contrast for those particular two colors. Due to this striking color clash, the term opposite colors is often considered more appropriate than "complementary colors". Which pairs of colors are considered complementary depends on the color theory one uses:  On the traditional color wheel developed in the 18th century, used by Claude Monet and Vincent van Gogh and other painters, and still used by many artists today, the primary colors were considered to be red, yellow, and blue, and the primary–secondary complementary pairs are red–green (Christmas), blue-orange (Westwood), and yellow–purple (Mesa High).
Primary color
A set of primary colors is, most tangibly, a set of "real" physical pigmented media or colored lights that can be combined in varying amounts to produce a "gamut" of colors. This is the essential method used in applications that are intended to elicit the perception of diverse sets of color, e.g. electronic displays, color printing, and paintings. Perceptions associated with a given combination of primary colors are predicted by applying the appropriate mixing model (additive, subtractive, additive averaging etc.) that embodies the underlying physics of how light interacts with the media and ultimately the retina.
Color mixing
There are two types of color mixing: "Additive" and "Subtractive". In both cases, there are three primary colors, three secondary colors (colors made from 2 of the three primary colors in equal amounts), and one tertiary color made from all three primary colors. This point is a common source of confusion, as there are different sets of primary colors depending on whether you are working with additive or subtractive mixing. The additive mixing of colors is unintuitive as it does not correspond to the mixing of physical substances (such as paint) which would correspond to subtractive mixing. For instance, one can additively mix yellow and blue by shining yellow light together with blue light, which will result in not green but a white light.
Comparison of color models in computer graphics
This article provides introductory information about the RGB, HSV, and HSL color models from a computer graphics (Web page, image) perspective. An introduction to colors is also provided to support the main discussion. First, "color" refers to the human brain's subjective interpretation of combinations of a narrow band of wavelengths of light. For this reason, the definition of "color" is not based on a strict set of physical phenomena. Therefore, even basic concepts like "primary colors" are not clearly defined. For example, traditional "Painter's Colors" use red, blue, and yellow as the primary colors, "Printer's Colors" use cyan, yellow, and magenta, and "Light Colors" use red, green, and blue.
RGB color model
The RGB color model is an additive color model in which red, green and blue light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue. The main purpose of the RGB color model is for the sensing, representation and display of images in electronic systems, such as televisions and computers, though it has also been used in conventional photography. Before the electronic age, the RGB color model already had a solid theory behind it, based in human perception of colors. RGB is a "device-dependent" color model: different devices detect or reproduce a given RGB value differently, since the color elements (such as phosphors or dyes) and their response to the individual R, G, and B levels vary from manufacturer to manufacturer, or even in the same device over time.
List of colors by shade
This is a list of colors sorted by shade. White is a balanced combination of all the colors of the visible light spectrum, or of a pair of complementary colors, or of three or more colors, such as additive primary colors. It is a neutral or achromatic ("without color") color, like black and gray. Achromatic grays are colors between black and white with no hue. Chromatic grays are achromatic grays mixed with warm hues such as orange ("warm grays") or cool hues such as azure ("cool grays"). This gray color template includes both achromatic and chromatic grays. Black is the darkest color, the result of the absence or complete absorption of 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.
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.
CIE 1931 color space
The CIE 1931 color spaces were the first defined quantitative links between distributions of wavelengths in the electromagnetic visible spectrum, and physiological perceived colors in human color vision. The mathematical relationships that define these color spaces are essential tools for color management, important when dealing with color inks, illuminated displays, and recording devices such as digital cameras. The CIE 1931 RGB color space and CIE 1931 XYZ color space were created by the International Commission on Illumination (CIE) in 1931. They resulted from a series of experiments done in the late 1920s by William David Wright and John Guild.

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.

Color wheel
A color wheel or colour circle is an abstract illustrative organization of color hues around a circle, which shows the relationships between primary colors, secondary colors, tertiary colors etc. Some sources use the terms "color wheel" and "color circle" interchangeably; however, one term or the other may be more prevalent in certain fields or certain versions as mentioned above. For instance, some reserve the term "color wheel" for mechanical rotating devices, such as color tops or filter wheels. Others classify various color wheels as "color disc", "color chart", and "color scale" varieties.

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.
Black
Black is the darkest color, the result of the absence or complete absorption of visible light. It is an achromatic color, literally a color without hue, like white (its opposite) and gray. It is often used symbolically or figuratively to represent darkness, while white represents light. Black ink is the most common color used for printing books, newspapers and documents, because it has the highest contrast with white paper and is the easiest to read. For the same reason, black text on a white screen is the most common format used on computer screens. In color printing it is used along with the subtractive primaries cyan, yellow, and magenta, in order to help produce the darkest shades.
Shaivism
Shaivism (Śaivam) is one of the major traditions within Hinduism that reveres Shiva as the Supreme Being or its metaphysical concept of Brahman. The followers of Shaivism are called "Shaivites" or "Saivites". Like much of Hinduism, the Shaiva have many sub-traditions, ranging from devotional dualistic theism such as Shaiva Siddhanta to yoga-oriented monistic non-theism such as Kashmiri Shaivism. It considers both the Vedas and the Agama texts as important sources of theology. Shaivism has ancient roots, traceable in the Vedic literature of 2nd millennium BCE, but this is in the form of the Vedic deity Rudra.
White
White is the lightest color and is achromatic (having no hue), because it fully reflects and scatters all the visible wavelengths of light. It is the color of fresh snow, chalk and milk, and is the opposite of black. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore a white toga as a symbol of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity. It was the royal color of the Kings of France, and of the monarchist movement that opposed the Bolsheviks during the Russian Civil War (1917–1922).
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.
Entertainment
Entertainment is a form of activity that holds the attention and interest of an audience, or gives pleasure and delight. It can be an idea or a task, but is more likely to be one of the activities or events that have developed over thousands of years specifically for the purpose of keeping an audience's attention. Although people's attention is held by different things, because individuals have different preferences in entertainment, most forms are recognisable and familiar. Storytelling, music, drama, dance, and different kinds of performance exist in all cultures, were supported in royal courts, developed into sophisticated forms and over time became available to all citizens.
Azerbaijani rug
Azerbaijani rugs () are a product of Azerbaijan and Iranian Azerbaijan, an ancient center of carpet weaving. The Azerbaijani rug is a traditional handmade textile of various sizes, with dense texture and a pile or pile-less surface, whose patterns are characteristic of Azerbaijan's many carpet-making regions. Traditionally, since ancient times the carpets were used in Azerbaijan to cover floors, decorate interior walls, sofas, chairs, beds and tables. Carpet making is a family tradition transferred orally and through practice, with carpet making and rug making being predominantly a women's occupation.
