Color or Colour is the visual perception based on the electromagnetic spectrum. Though color is not an inherent property of matter, color perception is related to an object's light absorption, reflection, emission spectra, and interference. For most humans, colors are perceived in the visible light spectrum with three types of cone cells (trichromacy). Other animals may have a different number of cone cell types or have eyes sensitive to different wavelength, such as bees that can distinguish ultraviolet, and thus have a different color sensitivity range. Animal perception of color originates from different light wavelength or spectral sensitivity in cone cell types, which is then processed by the brain.
In zoology, a scale is a small rigid plate that grows out of an animal's skin to provide protection. In lepidopterans, scales are plates on the surface of the insect wing, and provide coloration. Scales are quite common and have evolved multiple times through convergent evolution, with varying structure and function.
Peafowl is a common name for two bird species of the genus Pavo and one species of the closely related genus Afropavo within the tribe Pavonini of the family Phasianidae. Male peafowl are referred to as peacocks, and female peafowl are referred to as peahens.
The common kingfisher, also known as the Eurasian kingfisher and river kingfisher, is a small kingfisher with seven subspecies recognized within its wide distribution across Eurasia and North Africa. It is resident in much of its range, but migrates from areas where rivers freeze in winter.
The speculum is a patch, often distinctly coloured, on the secondary wing feathers, or remiges, of some birds.
Vitreous enamel, also called porcelain enamel, is a material made by fusing powdered glass to a substrate by firing, usually between 750 and 850 °C. The powder melts, flows, and then hardens to a smooth, durable vitreous coating. The word vitreous comes from the Latin vitreus, meaning "glassy".
Iridescence is the phenomenon of certain surfaces that appear gradually to change colour as the angle of view or the angle of illumination changes. Iridescence is caused by wave interference of light in microstructures or thin films. Examples of iridescence include soap bubbles, feathers, butterfly wings and seashell nacre, and minerals such as opal. Pearlescence is a related effect where some or most of the reflected light is white. The term pearlescent is used to describe certain paint finishes, usually in the automotive industry, which actually produce iridescent effects.
The Silkie is a breed of chicken named for its atypically fluffy plumage, which is said to feel like silk and satin. The breed has several other unusual qualities, such as black skin and bones, blue earlobes, and five toes on each foot, whereas most chickens have only four. They are often exhibited in poultry shows, and also appear in various colors. In addition to their distinctive physical characteristics, Silkies are well known for their calm and friendly temperament. It is among the most docile of poultry. Hens are also exceptionally broody, and care for young well. Although they are fair layers themselves, laying only about three eggs a week, they are commonly used to hatch eggs from other breeds and bird species due to their broody nature. Silkie chickens have been bred to have a wide variety of colors which include but are not limited to: Black, Blue, Buff, Partridge, Splash, White, Lavender, Paint and Porcelain.
Wilson's bird-of-paradise is a species of passerine bird of the family Paradisaeidae.
Cloisonné is an ancient technique for decorating metalwork objects with colored material held in place or separated by metal strips or wire, normally of gold. In recent centuries, vitreous enamel has been used, but inlays of cut gemstones, glass and other materials were also used during older periods; indeed cloisonné enamel very probably began as an easier imitation of cloisonné work using gems. The resulting objects can also be called cloisonné. The decoration is formed by first adding compartments to the metal object by soldering or affixing silver or gold as wires or thin strips placed on their edges. These remain visible in the finished piece, separating the different compartments of the enamel or inlays, which are often of several colors. Cloisonné enamel objects are worked on with enamel powder made into a paste, which then needs to be fired in a kiln. If gemstones or colored glass are used, the pieces need to be cut or ground into the shape of each cloison.
Azure is the color between cyan and blue on the spectrum of visible light. It is often described as the color of the sky on a clear day.
A melanosome is an organelle found in animal cells and is the site for synthesis, storage and transport of melanin, the most common light-absorbing pigment found in the animal kingdom. Melanosomes are responsible for color and photoprotection in animal cells and tissues.
The black sicklebill is a large member of the birds of paradise family, Paradisaeidae. This species is found throughout most of central New Guinea and the Vogelkop region to the northwest in montane forests at altitudes from 1,800 to 2,150 m.
Lawes's parotia, is a medium-sized passerine of the bird-of-paradise family, Paradisaeidae. It is distributed and endemic to mountain forests of southeast and eastern Papua New Guinea. Occasionally, the eastern parotia is considered a subspecies of P. lawesii. The species is similar to the western parotia.
A lapel pin, also known as an enamel pin, is a small pin worn on clothing, often on the lapel of a jacket, attached to a bag, or displayed on a piece of fabric. Lapel pins can be ornamental or can indicate the wearer's affiliation with a cause or an organization, such as a fraternal order or religious order; in the case of a chivalric order, the lapel pin is in the form of a rosette. Before the popularity of wearing lapel pins, boutonnières were worn.
The satinbirds or cnemophilines, are a family, Cnemophilidae of passerine birds which consists of four species found in the mountain forests of New Guinea. They were originally thought to be part of the birds-of-paradise family Paradisaeidae until genetic research suggested that the birds are not closely related to birds-of-paradise at all and are perhaps closer to berry peckers and longbills (Melanocharitidae). The current evidence suggests that their closest relatives may be the cuckoo-shrikes (Campephagidae).
Structural coloration in animals, and a few plants, is the production of colour by microscopically structured surfaces fine enough to interfere with visible light instead of pigments, although some structural coloration occurs in combination with pigments. For example, peacock tail feathers are pigmented brown, but their microscopic structure makes them also reflect blue, turquoise, and green light, and they are often iridescent.
Mexican featherwork, also called "plumería", was an important artistic and decorative technique in the pre-Hispanic and colonial periods in what is now Mexico. Although feathers have been prized and feather works created in other parts of the world, those done by the amanteca or feather work specialists impressed Spanish conquerors, leading to a creative exchange with Europe. Featherwork pieces took on European motifs in Mexico. Feathers and feather works became prized in Europe. The "golden age" for this technique as an art form was from just before the Spanish conquest to about a century afterwards. At the beginning of the 17th century, it began a decline due to the death of the old masters, the disappearance of the birds that provide fine feathers and the depreciation of indigenous handiwork. Feather work, especially the creation of "mosaics" or "paintings" principally of religious images remained noted by Europeans until the 19th century, but by the 20th century, the little that remained had become a handcraft, despite efforts to revive it. Today, the most common feather objects are those made for traditional dance costumes, although mosaics are made in the state of Michoacán, and feather trimmed huipils are made in the state of Chiapas.
Hunan embroidery, or Xiang embroidery, as one of the traditional folk arts of China, together with Cantonese embroidery, Sichuan embroidery and Suzhou embroidery, is regarded as the four most distinguished embroidery styles in China. It is a general name for the embroidery products which rise from and are mostly produced at Changsha, Hunan, with distinct characteristics of Chu culture. Hunan embroidery is particularly famous in embroidering with silk thread, and the patterns have a high sense of reality. In 2006, Hunan embroidery was selected into the first batch of national intangible cultural heritage list.
Ji ; pinyin: Jī) ,Zanzi or Zan ; pinyin: Zānzi or zān) for short) and Chai(Chinese: 钗); pinyin: Chāi) are generic terms for hairpin in China. 'Ji' is also the term used for hairpins of the Qin dynasty. The earliest form of Chinese hair stick was found in the Neolithic Hemudu culture relics; the hair stick was called Ji ; pinyin: Jī), and were made from bones, horns, stones, and jade.
