Orange (color)
Orange is the colour between yellow and red on the spectrum of visible light. The human eyes perceive orange when observing light with a dominant wavelength between roughly 585 and 620 nanometres. In traditional colour theory, it is a secondary colour of pigments, produced by mixing yellow and red. In the RGB colour model, it is a tertiary colour. It is named after the fruit of the same name. The orange colour of many fruits and vegetables, such as carrots, pumpkins, sweet potatoes, and oranges, comes from carotenes, a type of photosynthetic pigment. These pigments convert the light energy that the plants absorb from the Sun into chemical energy for the plants' growth. Similarly, the hues of autumn leaves are from the same pigment after chlorophyll is removed. In Europe and the United States, surveys show that orange is the colour most associated with amusement, the unconventional, extroversion, warmth, fire, energy, activity, danger, taste and aroma, the autumn and Allh ...

Delicate Arch
Delicate Arch is a freestanding natural arch located in Arches National Park, near Moab in Grand County, Utah, United States. The arch is the most widely recognized landmark in Arches National Park and is depicted on Utah license plates and a postage stamp commemorating Utah's centennial anniversary of admission to the Union in 1896. The Olympic torch relay for the 2002 Winter Olympics passed through the arch. History Because of its distinctive shape, the arch was known as "the Chaps" and "the Schoolmarm's Bloomers" by local cowboys. Many other names have been applied to this arch including "Bloomers Arch", "Marys Bloomers", "Old Maids Bloomers", "Pants Crotch", "Salt Wash Arch", and "School Marms Pants". The arch was given its current name by Frank Beckwith, leader of the Arches National Monument Scientific Expedition, who explored the area in the winter of 1933–1934. Although there is a rumor that the names of Delicate Arch and Landscape Arch were inadvertently ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orange (fruit)
The orange, also called sweet orange to distinguish it from the bitter orange (''Citrus × aurantium''), is the fruit of a tree in the family (biology), family Rutaceae. Botanically, this is the hybrid Citrus × sinensis, ''Citrus'' × ''sinensis'', between the pomelo (''Citrus maxima'') and the mandarin orange (''Citrus reticulata''). The chloroplast genome, and therefore the maternal line, is that of pomelo. There are many related hybrids including of mandarins and sweet orange. The sweet orange has had its full Whole genome sequencing, genome sequenced. The orange originated in a region encompassing Northern and southern China, Southern China, Northeast India, and Myanmar; the earliest mention of the sweet orange was in Chinese literature in 314 BC. Orange trees are widely grown in tropical and subtropical areas for their sweet fruit. The fruit of the Citrus × sinensis, orange tree can be eaten fresh or processed for its juice or fragrant peel (fruit), peel. In 2022, 76 mil ...

Christian Democracy
Christian democracy is an ideology inspired by Christian social teaching to respond to the challenges of contemporary society and politics. Christian democracy has drawn mainly from Catholic social teaching and neo-scholasticism, as well as the Neo-Calvinist tradition within Christianity; it later gained ground with Lutherans and Pentecostals, among other denominational traditions of Christianity in various parts of the world. During the nineteenth century, its principal concerns were to reconcile Catholicism with democracy, to answer the " social question" surrounding capitalism and the working class, and to resolve the tensions between church and state. In the twentieth century, Christian democrats led postwar Western and Southern Europe in building modern welfare states and constructing the European Union. Furthermore; in the late twentieth and early twenty-first century, Christian democracy has gained support in Eastern Europe among former communist states sufferi ...

Political Colour
Political colours are colours used to represent a political ideology, movement or party, either officially or unofficially. They represent the intersection of colour symbolism and political symbolism. Politicians making public appearances will often identify themselves by wearing rosettes, flowers, ties or ribbons in the colour of their political party. Parties in different countries with similar ideologies sometimes use similar colours. As an example the colour red symbolises left-wing ideologies in many countries (leading to such terms as " Red Army" and " Red Scare"), while the colour blue is often used for conservatism, the colour yellow is most commonly associated with liberalism and right-libertarianism, and Green politics is named after the ideology's political colour. The political associations of a given colour vary from country to country, and there are exceptions to the general trends, for example red has historically been associated with Christianity, ...

House Of Orange
The House of Orange-Nassau (, ), also known as the House of Orange because of the prestige of the princely title of Orange, also referred to as the Fourth House of Orange in comparison with the other noble houses that held the Principality of Orange, is the current reigning house of the Netherlands. A branch of the European House of Nassau, the house has played a central role in the politics and government of the Netherlands and elsewhere in Europe, particularly since William the Silent organised the Dutch Revolt against Spanish rule, which after the Eighty Years' War (1568–1648) led to an independent Dutch state. William III of Orange led the resistance of the Netherlands and Europe to Louis XIV of France and orchestrated the Glorious Revolution in England that established parliamentary rule. Similarly, Queen Wilhelmina of the Netherlands was instrumental in the Dutch resistance during World War II. Several members of the house served during the Eighty Years war and ...

National Colours
National colours are frequently part of a country's set of national symbols. Many states and nations have formally adopted a set of colours as their official "national colours" while others have '' de facto'' national colours that have become well known through popular use. National colours often appear on a variety of different media, from the nation's flag to the colours used in sports. Before World War I, they also served as the colours of different military uniforms for each nation or region. Africa North America Sub-national colours South America Asia Sub-national colours Europe Sub-national colours Oceania Sub-national colours Countries with limited or no recognition These are the national colours for countries or states that have limited or no recognition. Former countries Caliphates Ancient/Imperial Chinese dynasties Supranational organisations Some noted supranational organisations like the United Nations and the European U ...

Allhallowtide
Allhallowtide, Hallowtide, Allsaintstide, or the Hallowmas season is the Western Christian Church, Western Christian season encompassing the triduum of All Saints' Eve (Halloween), All Saints' Day (All Hallows') and All Souls' Day, as well as the International Day of Prayer for the Persecuted Church (observed on the first Sunday of November) and Remembrance Sunday (observed on the second Sunday in November) in some traditions. The period begins on 31 October annually. Allhallowtide is a "time to remember the dead, including Christian martyrs, martyrs, saints, and all faithful departed Christians." The present date of Hallowmas (All Saints' Day) and thus also of its vigil (Hallowe'en) was established for Rome perhaps by Pope Gregory III (731–741) and was made of obligation throughout the Frankish Empire by Louis the Pious in 835. Elsewhere, other dates were observed even later, with the date in Ireland being 20 April. In the early 11th century, the modern date of All Souls' Day wa ...

Autumn
Autumn, also known as fall (especially in US & Canada), is one of the four temperate seasons on Earth. Outside the tropics, autumn marks the transition from summer to winter, in September (Northern Hemisphere) or March ( Southern Hemisphere). Autumn is the season when the duration of daylight becomes noticeably shorter and the temperature cools considerably. Day length decreases and night length increases as the season progresses until the winter solstice in December (Northern Hemisphere) and June (Southern Hemisphere). One of its main features in temperate climates is the striking change in colour of the leaves of deciduous trees as they prepare to shed. Date definitions Some cultures regard the autumnal equinox as "mid-autumn", while others with a longer temperature lag treat the equinox as the start of autumn. In the English-speaking world of high latitude countries, autumn traditionally began with Lammas Day and ended around Hallowe'en, the approximate mid-poin ...

Chlorophyll
Chlorophyll is any of several related green pigments found in cyanobacteria and in the chloroplasts of algae and plants. Its name is derived from the Greek words (, "pale green") and (, "leaf"). Chlorophyll allows plants to absorb energy from light. Those pigments are involved in oxygenic photosynthesis, as opposed to bacteriochlorophylls, related molecules found only in bacteria and involved in anoxygenic photosynthesis. Chlorophylls absorb light most strongly in the blue portion of the electromagnetic spectrum as well as the red portion. Conversely, it is a poor absorber of green and near-green portions of the spectrum. Hence chlorophyll-containing tissues appear green because green light, diffusively reflected by structures like cell walls, is less absorbed. Two types of chlorophyll exist in the photosystems of green plants: chlorophyll ''a'' and ''b''. History Chlorophyll was first isolated and named by Joseph Bienaimé Caventou and Pierre Joseph Pelletier in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photosynthetic Pigment
A photosynthetic pigment (accessory pigment; chloroplast pigment; antenna pigment) is a pigment that is present in chloroplasts or photosynthetic bacteria and captures the light energy necessary for photosynthesis.

Carotene
The term carotene (also carotin, from the Latin ''carota'', "carrot") is used for many related unsaturated hydrocarbon substances having the formula C40Hx, which are synthesized by plants but in general cannot be made by animals (with the exception of some aphids and spider mites which acquired the synthesizing genes from fungi). Carotenes are photosynthetic pigments important for photosynthesis. Carotenes contain no oxygen atoms. They absorb ultraviolet, violet, and blue light and scatter orange or red light, and yellow light(in low concentrations). Carotenes are responsible for the orange colour of the carrot, after which this class of chemicals is named, and for the colours of many other fruits, vegetables and fungi (for example, sweet potatoes, chanterelle and orange cantaloupe melon). Carotenes are also responsible for the orange (but not all of the yellow) colours in dry foliage. They also (in lower concentrations) impart the yellow coloration to milk-fat and butter. ...
