Blue-grey
Livid is a medium bluish-gray color. This color name comes from the Latin color term ''lividus'' meaning "'a dull leaden-blue color', and also used to describe the color of contused flesh, leading to the English expression 'black and blue'". The first recorded use of ''livid'' as a color name in English was in 1622. There is a range of colors called ''livid'' colors that combine the colors blue and gray. Some of these colors are shown below. Livid (blue-gray) is the opposite concept from brown. Brown colors are mainly ''dark orange'' and ''dark red'' colors—warm colors on the warm color side of the color wheel, while blue-gray (livid) colors are mainly ''dark blue'' and ''dark azure'' colors—colors on the opposite side of the color wheel—cool colors on the cool color side of the color wheel. Alternate names are blue-gray (American English) or blue-grey (British English), which was a name introduced by Crayola for a crayon color used from 1958 to 1990. Thus, the norm ...

Blue-grey Tanager
The blue-gray tanager (''Thraupis episcopus'') is a medium-sized South American songbird of the tanager family, Thraupidae. Its range is from Mexico south to northeast Bolivia and northern Brazil, all of the Amazon Basin, except the very south. It has been introduced to Lima (Peru). On Trinidad and Tobago, this bird is called blue jean. Taxonomy In 1760 the French zoologist Mathurin Jacques Brisson included a description of the blue-grey tanager in his ''Ornithologie'' based on a specimen collected in Brazil. He used the French name ''L'evesque'' and the Latin name ''Episcopus avis''. The two stars (**) at the start of the paragraph indicates that Brisson based his description on the examination of a specimen. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the twelfth edition he a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argyria
Argyria or argyrosis is a condition caused by excessive exposure to chemical compounds of the element silver, or to silver dust. The most dramatic symptom of argyria is that the skin turns blue or blue-grey. It may take the form of ''generalized argyria'' or ''local argyria''. Generalized argyria affects large areas over much of the visible surface of the body. Local argyria shows in limited regions of the body, such as patches of skin, parts of the mucous membrane or the conjunctiva. The terms argyria and argyrosis have long been used interchangeably, with argyria being used more frequently. Argyrosis has been used particularly in referring to argyria of the conjunctiva, but the usage has never been consistent and cannot be relied on except where it has been explicitly specified. The term is from the grc, ἄργυρος (''argyros'', 'silver'). Pathophysiology In humans and other animals, chronic intake of silver products commonly leads to gradual accumulation of silver comp ...

Gray
Grey (more common in British English) or gray (more common in American English) is an intermediate color between black and white. It is a neutral or achromatic color, meaning literally that it is "without color", because it can be composed of black and white. It is the color of a cloud-covered sky, of ash and of lead. The first recorded use of ''grey'' as a color name in the English language was in 700 CE.Maerz and Paul ''A Dictionary of Color'' New York:1930 McGraw-Hill Page 196 ''Grey'' is the dominant spelling in European and Commonwealth English, while ''gray'' has been the preferred spelling in American English; both spellings are valid in both varieties of English. In Europe and North America, surveys show that grey is the color most commonly associated with neutrality, conformity, boredom, uncertainty, old age, indifference, and modesty. Only one percent of respondents chose it as their favorite color. Etymology ''Grey'' comes from the Middle English or , ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue-gray Mouse
The blue-gray mouse (''Pseudomys glaucus'') is an Australian rodent species that is only known by a few specimens found in Eastern Australia, and since presumed to have become extinct. Taxonomy The species was described by Oldfield Thomas in 1910. The number of specimens identified as ''Pseudomys glaucus'' is limited to three, two found in the northeastern state of Queensland and a single specimen collected to the south at Cryon in New South Wales. Description A species of ''Pseudomys'', these Australian rodents resembled the familiar house mouse (''Mus musculus''). The body of ''P. glaucus'' was robust with fine and dense fur, white at the underside and a pale blue-grey colour over the upperparts of the fur. The measurement of each of the three known specimens was 95 millimetres for the head and body combined, with a white-haired tail that was slightly longer (100 mm.) The weight range was 25 to 30 grams. References {{Taxonbar, from=Q882869 Pseudomys Mammals des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxford English Dictionary
The ''Oxford English Dictionary'' (''OED'') is the first and foundational historical dictionary of the English language, published by Oxford University Press (OUP). It traces the historical development of the English language, providing a comprehensive resource to scholars and academic researchers, as well as describing usage in its many variations throughout the world. Work began on the dictionary in 1857, but it was only in 1884 that it began to be published in unbound fascicles as work continued on the project, under the name of ''A New English Dictionary on Historical Principles; Founded Mainly on the Materials Collected by The Philological Society''. In 1895, the title ''The Oxford English Dictionary'' was first used unofficially on the covers of the series, and in 1928 the full dictionary was republished in 10 bound volumes. In 1933, the title ''The Oxford English Dictionary'' fully replaced the former name in all occurrences in its reprinting as 12 volumes with a one-v ...

Blue Grey Cattle
The Blue Grey is a cattle hybrid traditional in south-western Scotland and north-western England. It is blue roan in colour, and results from breeding a black Galloway cow to a white Shorthorn bull. It is reared principally as a suckler cow, and is particularly well suited to upland grazing. History In south-western Scotland and north-western England, Shorthorn bulls were used from the early nineteenth century on black Galloway cows to produce vigorous hybrid calves. If the bull was white, the calf was blue roan in colour; these were easily recognisable and were much in demand. In the later nineteenth century, selection of the Whitebred Shorthorn was begun specifically to supply white sires for production of these calves. Characteristics The Blue Grey is blue roan in colour, and is polled (without horns). Cows have high amounts of body fat compared to other hybrids in similar overall condition, and are able to produce adequate quantities of milk even on poor grazing. U ...

Haplopelma Lividum
The cobalt blue tarantula or ''Cyriopagopus lividus'' is a species of tarantula which is in the family Theraphosidae which is native to Myanmar and over the border into Thailand. It was originally described as ''Haplopelma lividum''. Description The cobalt blue tarantula is a medium-sized tarantula with a leg span around 13 cm (5 in). It is noted for its iridescent blue legs and light gray prosoma and opisthosoma, the latter of which may contain darker gray chevrons. Males and females look the same until the ultimate (final) molt of the males. At this point, the male exhibits sexual dimorphism in the form of a light tan or bronze coloration and legginess. Additionally, males gain a palpal bulb on the pedipalps and tibial apophyses (mating hooks). The female eventually becomes larger than the male and lives years longer. The cobalt blue tarantula is a fossorial A fossorial () animal is one adapted to digging which lives primarily, but not solely, underground. Some ex ...

Calliphora Livida
''Calliphora livida'' is a member of the family Calliphoridae, the blow flies. This large family includes the genus ''Calliphora'', the "blue bottle flies". This genus is important in the field of forensic entomology because of its value in post-mortem interval estimation. Taxonomy ''Calliphora livida'', known as the slow-flying and loud-buzzing blue bottle fly, was first discovered by Jean-Baptiste Robineau-Desvoidy who originally thought ''C. livida'' was part of the species ''Calliphora viridescens''. Robineau-Desvoidy described ''C. viridescens'' in 1830, but it was not until 1948 that ''C. livida'' was described as a separate species; in 1948, D. G. Hall introduced one of the first textbooks of entomology, where he described a number of new species including ''C. livida''. ''C. livida'' is also very similar to the species '' C. coloradensis'', which when suffering from teneral has similar genal dilation.

Metallic Color
A metallic color is a color that appears to be that of a polished metal. The visual sensation usually associated with metals is its metallic shine. This cannot be reproduced by a simple solid color, because the shiny effect is due to the material's brightness varying with the surface angle to the light source. In addition, there is no mechanism for showing metallic or fluorescent colors on a computer without resorting to rendering software which simulates the action of light on a shiny surface. Consequently in art and in heraldry one would normally use a metallic paint that glitters like a real metal. For example, to create a painting that gave the impression of gold appearing in the painting, a metallic paint that glitters in an approximation of real gold would be used; a solid color does not aesthetically "read" as gold. Especially in sacral art in Christian churches, real gold (as gold leaf) was used for rendering gold in paintings, e.g. for the halo of saints. Gold can also ...
