Buff (colour)
Buff () is a light brownish yellow, ochreous colour, typical of buff leather. Buff is a mixture of yellow ochre and white: two parts of white lead and one part of yellow ochre produces a good buff, or white lead may be tinted with French ochre alone. As an RYB quaternary colour, it is the colour produced by an equal mix of the tertiary colours citron and russet. Etymology The first recorded use of the word ''buff'' to describe a colour was in ''The London Gazette'' of 1686, describing a uniform to be "...a Red Coat with a Buff-colour'd lining". It referred to the colour of undyed buffalo leather, such as soldiers wore as some protection: an eyewitness to the death in the Battle of Edgehill (1642) of Sir Edmund Verney noted "he would neither put on arms rmouror buff coat the day of the battle". Such buff leather was suitable for '' buffing'' or serving as a '' buffer'' between polished objects. It is not clear which bovine "''buffalo''" referred to, but it ma ...

RYB Color Model
RYB (an abbreviation of red–yellow–blue) is a subtractive color model used in art and applied design in which red, yellow, and blue pigments are considered primary colors. Under traditional color theory, this set of primary colors was advocated by Moses Harris, Michel Eugène Chevreul, Johannes Itten and Josef Albers, and applied by countless artists and designers. The RYB color model underpinned the color curriculum of the Bauhaus, Ulm School of Design and numerous art and design schools that were influenced by the Bauhaus, including the IIT Institute of Design (founded as the New Bauhaus), Black Mountain College, Design Department Yale University, the Shillito Design School, Sydney, and Parsons School of Design, New York. In this context, the term ''primary color'' refers to three exemplar colors (red, yellow, and blue) as opposed to specific pigments. As illustrated, in the RYB color model, red, yellow, and blue are intermixed to create secondary color segments ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buff Coat
The European buff coat is an item of leather clothing that was primarily worn by cavalry and officers during the 17th century, but also worn by a small number of infantry. It was often worn under iron or steel armour for the torso ( breastplate and backplate). The buff coat was derived from the simple leather jerkins employed by huntsmen and soldiers during the Tudor period, these in turn deriving from the arming doublet. The name of the jacket, as well as its characteristic tan or '' buff'' colour, derives from the buffalo or ox hide from which it was commonly made. Production, appearance and variation The buff coat was worn as European military attire from around 1600 through to the 1680s. The origin of the term 'buff' in relation to the coat refers to leather obtained from the "European buffalo" (available sources do not specify what species this term means, but it most probably refers to the wisent), which also gave rise to the term '' buff'' for its light tan colour.

Buff Arches
The buff arches (''Habrosyne pyritoides'') is a moth of the family Drepanidae. The species was first described by Johann Siegfried Hufnagel in 1766. It is found throughout Europe and is well distributed in the British Isles except the far north of England and all of Scotland. They live in deciduous and coniferous forests with large populations of their foodplants, but also in gardens and parks. This is a distinctive and attractive species; its grey-brown forewings are marked with bold buff-orange "arches". The hindwings are grey with white margins. The wingspan is 40–45 mm. It flies from June to August and is attracted to light and sugar. The young caterpillars are dark brown to grey-brown and more clearly spotted than the later caterpillar stages. These are brown-red and have a narrow dark dorsal line with indistinct light side spots. They have white spots on the sides of the three front abdominal segments, which become smaller to the rear, or just such a spot on the ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Camouflage
Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. A third approach, motion dazzle, confuses the observer with a conspicuous pattern, making the object visible but momentarily harder to locate. The majority of camouflage methods aim for crypsis, often through a general resemblance to the background, high contrast disruptive coloration, eliminating shadow, and countershading. In the open ocean, where there is no background, the principal methods of camouflage are transparency, silvering, and countershading, while the bioluminescence, ability to produce light is among other things used for counter-illumination on the undersides of cephalopods such as squid. Some animals, such as chameleons and octopuses, are capable of Active ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loess
A loess (, ; from ) is a clastic rock, clastic, predominantly silt-sized sediment that is formed by the accumulation of wind-blown dust. Ten percent of Earth's land area is covered by loesses or similar deposition (geology), deposits. A loess is a periglacial or aeolian processes, aeolian (windborne) sediment, defined as an accumulation of 20% or less of clay with a balance of roughly equal parts sand and silt (with a typical grain size from 20 to 50 micrometers), often loosely cemented by calcium carbonate.

Tunic
A tunic is a garment for the torso, usually simple in style, reaching from the shoulders to a length somewhere between the hips and the ankles. It might have arm-sleeves, either short or full-length. Most forms have no fastenings. The name derives from the Latin '' tunica'', the basic garment worn by both men and women in Ancient Rome, which in turn was based on earlier Greek garments that covered wearers' waists. The term is likely borrowed from a Semitic word *''kittan'' with metathesis. The word khiton () is of the same origin. Ancient era Roman tunic The Roman ''tunica'' was adopted by Roman citizens in the 3rd century BCE. It was often worn by Roman citizens and by non-citizens alike. However, citizens might wear it under the toga, especially at formal occasions. The length of the garment, the presence or lack of stripes, as well as their width and ornamentation, would indicate the wearer's status in Roman society. Roman senators, for example, used the '' laticla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enthusiast
In modern usage, enthusiasm refers to intense enjoyment, interest, or approval expressed by a person. The term is related to playfulness, inventiveness, optimism, zest, verve, and high energy. The word was originally used to refer to a person possessed by God, or someone who exhibited intense piety. Historical usage The word ''enthusiasm'' originates from the Greek from (, “in”) and (, “god”), meaning "inspired or possessed by god". Applied by the Greeks to manifestations of divine possession, by Apollo (as in the case of the Pythia), or by Dionysus (as in the case of the Bacchantes and Maenads), the term enthusiasm was also used in a transferred or figurative sense. Socrates taught that the inspiration of poets is a form of enthusiasm. The term was confined to a belief in religious inspiration, or to intense religious fervor or emotion. From this, a Syrian sect of the fourth century was known as the Enthusiasts. They believed that "by perpetual prayer, ascetic pr ...
