Citrine (colour)
Citrine is a colour, the most common reference for which is certain coloured varieties of quartz which are a medium deep shade of golden yellow. Citrine has been summarized at various times as yellow, greenish-yellow, brownish yellow or orange. The original reference point for the citrine colour was the citron fruit. The first recorded use of ''citrine'' as a colour in English was in 1386. It was borrowed from a medieval Latin and classical Latin word with the same meaning. In late medieval and early modern English the citrine colour-name was applied in a wider variety of contexts than it is today and could be "reddish or brownish yellow; or orange; or amber (distinguished from yellow)"."Citrine" in th''Middle English Dictionary''(late medieval English). In today's English citrine as a colour is mostly confined to the contexts of (1) gemstones, including quartz, and (2) some animal and plant names. E.g., the citrine wagtail (''Motacilla citreola''), an Asian bird species with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quartz
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The atoms are linked in a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at . Since the transformation is accompanied by a significant change in volume, it can easily induce microfracturing of ceramics or rocks passing through this temperature threshold. There are many different varieties of quartz, several of which are classified as gemstones. Since antiquity, varieties of quartz have been the most commonly used minerals in the making of jewelry and hardstone carvings, especially in Eurasia. Quartz is the mineral defining the val ...

Shades Of Yellow
Varieties of the color yellow may differ in hue, chroma (also called saturation, intensity, or colorfulness) or lightness (or value, tone, or brightness), or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a yellow or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below. Computer web color yellow Yellow (RGB) (X11 yellow) (color wheel yellow) The color box at right shows the most intense yellow representable in 8-bit RGB color model; yellow is a ''secondary'' color in an additive RGB space. This color is also called color wheel yellow. It is at precisely 60 degrees on the HSV color wheel, also known as the RGB color wheel ( Image of RGB color wheel:). Its complementary color is blue.

Citrine Forktail
The citrine forktail (''Ischnura hastata'') is a damselfly of the family Coenagrionidae. Description This species is 20–27 mm in length, and its hindwing is 11–15 mm long; it is thus considerably smaller than most European members of the genus ''Ischnura''. Adult males have a black head and thorax, with blue markings, and a largely yellow abdomen, with black markings on its upper surface. The term Citrine (colour), citrine refers to its yellowish colouration. Adult females are initially largely orange, marked with black above on the head and rear part of the abdomen. They undergo a colour change, through brown or olive to greyish, as they mature. Male citrine forktails are the only damselflies in the world with the pterostigma situated away from the leading edge of the wing. Distribution It is native to North America, North and South America, and there is a population on the Azores. The Azorean population is likely to have been present since the late 19th Centu ...

Citrine Wagtail
The citrine wagtail (''Motacilla citreola'') is a small songbird in the family Motacillidae. Etymology The term ''citrine'', and the specific name ''citreola'', refers to its yellowish colouration. Taxonomy Its systematics, phylogeny and taxonomy are subject of considerable debate in the early 21st century. This is because this bird forms a cryptic species complex with the eastern (''M. tschutschensis '') and western yellow wagtail (''M. flava''). Which of the many taxa in this group should properly refer to which population is unlikely to be resolved in the immediate future. ''Motacilla'' is the Latin name for the pied wagtail; although actually a diminutive of ''motare'', " to move about", from medieval times it led to the misunderstanding of ''cilla'' as "tail". The specific ''citreola'' is Latin for "lemon yellow". Description It is a slender, 15.5–17 cm long bird, with the long, constantly wagging tail characteristic of the genus '' Motacilla''.

Citron
The citron (''Citrus medica''), historically cedrate, is a large fragrant citrus fruit with a thick rind. It is said to resemble a 'huge, rough lemon'. It is one of the original citrus fruits from which all other citrus types developed through natural hybrid speciation or artificial hybridization. Though citron cultivars take on a wide variety of physical forms, they are all closely related genetically. It is used in Asian cuisine, traditional medicines, perfume, and religious rituals and offerings. Hybrids of citrons with other citrus are commercially more prominent, notably lemons and many limes. Etymology The fruit's English name "citron" derives ultimately from Latin, ''citrus'', which is also the origin of the genus name. Other languages A source of confusion is that ''citron'' in French and English are false friends, as the French word refers to the lemon, while the English word is translated ''cédrat''. Indeed, into the 16th century, the English name ''citron'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
