Dutch Flag
The national flag of the Netherlands ( nl, de Nederlandse vlag) is a horizontal tricolour of red, white, and blue. The current design originates as a variant of the late 16th century orange-white-blue '' Prinsenvlag'' ("Prince's Flag"), evolving in the early 17th century as the red-white-blue ''Statenvlag'' ("States Flag"), the naval flag of the States-General of the Dutch Republic, making the Dutch flag perhaps the oldest tricolour flag in continuous use.As a flag that symbolises the transformation from monarchy to republic, it has inspired both the derivative Russian flag, and after the French Revolution in 1789 the vertically striped French tricolour, both flags in turn influenced many other tricolours. During the economic crisis of the 1930s, the old Prince's Flag with the colour orange gained some popularity among some people. To end the confusion, the colours red, white and blue and its official status as the national flag of the Kingdom of the Netherlands were reaffirme ...

Triband (flag)
A triband is a vexillological style which consists of three stripes arranged to form a flag. These stripes may be two or three colors, and may be charged with an emblem in the middle stripe. Design Outside of the name, which requires three bands of color, there are no other requirements for what a triband must look like, so there are many flags that look very different from each other but are all considered tribands. Some triband flags (e.g. those of Croatia and Ghana) have their stripes positioned horizontally, while others (e.g. that of Italy) position the stripes vertically. Often the stripes on a triband are of equal length and width, though this is not always the case, as can be seen in the flags of Colombia and Canada. Symbols on tribands may be seals, such as on the Belizean flag, or any manner of emblems of significance to the area the flag represents, such as in the flags of Argentina, India and Lebanon. A triband is also a tricolor if the three stripes on the flag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tricolour (flag)
A tricolour () or tricolor () is a type of flag or banner design with a triband design which originated in the 16th century as a symbol of republicanism, liberty, or revolution. The flags of France, Italy, Romania, Mexico, and Ireland were all first adopted with the formation of an independent republic in the period of the French Revolution to the Revolutions of 1848, with the exception of the Irish tricolour, which dates from 1848 but was not popularised until the Easter Rising in 1916 and adopted in 1919. History The first association of the tricolour with republicanism is the orange-white-blue design of the Prince's Flag (''Prinsenvlag'', predecessor of the flags of the Netherlands), used from 1579 by William I of Orange-Nassau in the Eighty Years' War, establishing the independence of the Dutch Republic from the Spanish Empire. The flag of the Netherlands inspired both the French and Russian flags, which in turn inspired many further tricolour flags in other countrie ...

Standard Illuminant
A standard illuminant is a theoretical source of visible light with a spectral power distribution that is published. Standard illuminants provide a basis for comparing images or colors recorded under different lighting. CIE illuminants The International Commission on Illumination (usually abbreviated CIE for its French name) is the body responsible for publishing all of the well-known standard illuminants. Each of these is known by a letter or by a letter-number combination. Illuminants A, B, and C were introduced in 1931, with the intention of respectively representing average incandescent light, direct sunlight, and average daylight. Illuminants D represent variations of daylight, illuminant E is the equal-energy illuminant, while illuminants F represent fluorescent lamps of various composition. There are instructions on how to experimentally produce light sources ("standard sources") corresponding to the older illuminants. For the relatively newer ones (such as series D), exp ...

Commission Internationale De L'Éclairage
The International Commission on Illumination (usually abbreviated CIE for its French name, Commission internationale de l'éclairage) is the international authority on light, illumination, colour, and colour spaces. It was established in 1913 as a successor to the Commission Internationale de Photométrie, which was founded in 1900, and is today based in Vienna, Austria. Organization The CIE has six active divisions, each of which establishes technical committees to carry out its program: * Division 1: Vision and Colour * Division 2: Physical Measurement of Light and Radiation * Division 3: Interior Environment and Lighting Design * Division 4: Transportation and Exterior Applications * Division 6: Photobiology and Photochemistry * Division 8: Image Technology Two divisions are no longer active: * Division 5: Exterior Lighting and Other Applications * Division 7: General Aspects of Lighting The President of the CIE from 2019 is Dr Peter Blattner from Switzerland.

RAL Colour Standard
RAL is a color management, colour management system used in Europe that is created and administrated by the German (RAL non-profit LLC), which is a subsidiary of the German . In colloquial speech RAL refers to the RAL Classic system, mainly used for varnish and powder coating, but now there are reference panels for plastics as well. Approved RAL products are provided with a hologram to make unauthorised versions difficult to produce. Imitations may show different hue and colour when observed under various light sources. RAL colour space system RAL Classic In 1927, the German group (National Committee for Delivery and Quality Assurance) invented a collection of forty colours under the name of "RAL 840". Prior to that date manufacturers and customers had to exchange samples to describe a tint, whereas from then on they would rely on numbers. In the 1930s, the numbers were changed uniformly to four digits and the collection was renamed to "RAL 840 R" (R for revised). Around ...

Hex Triplet
Web colors are colors used in displaying web pages on the World Wide Web, and the methods for describing and specifying those colors. Colors may be specified as an RGB triplet or in hexadecimal format (a ''hex triplet'') or according to their common English names in some cases. A color tool or other graphics software is often used to generate color values. In some uses, hexadecimal color codes are specified with notation using a leading number sign (#). A color is specified according to the intensity of its red, green and blue components, each represented by eight bits. Thus, there are 24 bits used to specify a web color within the sRGB gamut, and 16,777,216 colors that may be so specified. Colors outside the sRGB gamut can be specified in Cascading Style Sheets by making one or more of the red, green and blue components negative or greater than 100%, so the color space is theoretically an unbounded extrapolation of sRGB similar to scRGB. Specifying a non-sRGB color this way req ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RGB Color Model
The RGB color model is an additive color model in which the red, green and blue primary colors of 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 red, green, and blue levels vary from manufacturer to manufacturer, or even in the same device over time. Thus an RGB value does not define the same ''color'' across d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CMYK Color Model
The CMYK color model (also known as process color, or four color) is a subtractive color model, based on the CMY color model, used in color printing, and is also used to describe the printing process itself. The abbreviation ''CMYK'' refers to the four ink plates used: cyan, magenta, yellow, and key (black). The CMYK model works by partially or entirely masking colors on a lighter, usually white, background. The ink reduces the light that would otherwise be reflected. Such a model is called ''subtractive'' because inks "subtract" the colors red, green and blue from white light. White light minus red leaves cyan, white light minus green leaves magenta, and white light minus blue leaves yellow. In additive color models, such as RGB, white is the "additive" combination of all primary colored lights, black is the absence of light. In the CMYK model, it is the opposite: white is the natural color of the paper or other background, black results from a full combination of colo ...

Chromaticity
Chromaticity is an objective specification of the quality of a color regardless of its luminance. Chromaticity consists of two independent parameters, often specified as hue (h) and colorfulness (s), where the latter is alternatively called saturation, chroma, intensity, or excitation purity. This number of parameters follows from trichromacy of vision of most humans, which is assumed by most models in color science. Quantitative description In color science, the white point of an illuminant or of a display is a neutral reference characterized by a chromaticity; all other chromaticities may be defined in relation to this reference using polar coordinates. The ''hue'' is the angular component, and the ''purity'' is the radial component, normalized by the maximum radius for that hue. Purity is roughly equivalent to the term "saturation" in the HSV color model. The property "hue" is as used in general color theory and in specific color models such as HSV and HSL color spaces, ...

Fess
In heraldry, a fess or fesse (from Middle English ''fesse'', from Old French ''faisse'', from Latin ''fascia'', "band") is a charge on a coat of arms (or flag) that takes the form of a band running horizontally across the centre of the shield.Woodcock & Robinson (1988), ''Oxford Guide to Heraldry'', p. 60. Writers disagree in how much of the shield's surface is to be covered by a fess or other ordinary, ranging from one-fifth to one-third. The ''Oxford Guide to Heraldry'' states that earlier writers including Leigh, Holme, and Guillim favour one-third, while later writers such as Edmondson favour one-fifth "on the grounds that a bend, pale, or chevron occupying one-third of the field makes the coat look clumsy and disagreeable."Woodcock & Robinson (1988), ''Oxford Guide to Heraldry'', p. 58. A fess is likely to be shown narrower if it is ''uncharged'', that is, if it does not have other charges placed on it, and/or if it is to be shown with charges above and below it; and show ...

Royal Decree
A decree is a legal proclamation, usually issued by a head of state (such as the president of a republic or a monarch), according to certain procedures (usually established in a constitution). It has the force of law. The particular term used for this concept may vary from country to country. The ''executive orders'' made by the President of the United States, for example, are decrees (although a decree is not exactly an order). Decree by jurisdiction Belgium In Belgium, a decree is a law of a community or regional parliament, e.g. the Flemish Parliament. France The word ''décret'', literally "decree", is an old legal usage in France and is used to refer to executive orders issued by the French President or Prime Minister. Any such order must not violate the French Constitution or Civil Code, and a party has the right to request an order be annulled in the French Council of State. Orders must be ratified by Parliament before they can be modified into legislative Acts. Specia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
