Color Naming System
The Color Naming System (CNS) is a systematic notation for named colors for computer applications using English language, English terms created by Berk et al. in 1982. System CNS uses ten color names, three of which (''black, white, gray'') are special, and has them combined or prefixed with several modifiers. The system expressed in Backus–Naur form looks something like this:. named-color := gray-color , chromatic-color gray-color := 'black' , 'white' , lightness gray gray := 'gray' , 'grey' chromatic-color := [ tint , shade ] hue , [ lightness , saturation ]? hue tint := 'whitish' , 'pale' , 'brilliant' , 'vivid' shade := 'blackish' , 'dim' , 'deep' , 'vivid' saturation := 'grayish' , 'moderate' , 'strong' , 'vivid' lightness := 'moderate' , 'very'? [ 'dark' , 'light' ] hue := splash-color? base-color , base-color '-' base-color base-color := 'red' , 'orange' , 'brown' , 'yellow' , ...

English Language
English is a West Germanic language of the Indo-European language family, with its earliest forms spoken by the inhabitants of early medieval England. It is named after the Angles, one of the ancient Germanic peoples that migrated to the island of Great Britain. Existing on a dialect continuum with Scots, and then closest related to the Low Saxon and Frisian languages, English is genealogically West Germanic. However, its vocabulary is also distinctively influenced by dialects of France (about 29% of Modern English words) and Latin (also about 29%), plus some grammar and a small amount of core vocabulary influenced by Old Norse (a North Germanic language). Speakers of English are called Anglophones. The earliest forms of English, collectively known as Old English, evolved from a group of West Germanic (Ingvaeonic) dialects brought to Great Britain by Anglo-Saxon settlers in the 5th century and further mutated by Norse-speaking Viking settlers starting in the 8th and 9th ...

Backus–Naur Form
In computer science, Backus–Naur form () or Backus normal form (BNF) is a metasyntax notation for context-free grammars, often used to describe the syntax of languages used in computing, such as computer programming languages, document formats, instruction sets and communication protocols. It is applied wherever exact descriptions of languages are needed: for instance, in official language specifications, in manuals, and in textbooks on programming language theory. Many extensions and variants of the original Backus–Naur notation are used; some are exactly defined, including extended Backus–Naur form (EBNF) and augmented Backus–Naur form (ABNF). Overview A BNF specification is a set of derivation rules, written as ::= __expression__ where: * is a ''nonterminal'' (variable) and the __expression__ consists of one or more sequences of either terminal or nonterminal symbols; * means that the symbol on the left must be replaced with the expression on the right. * mor ...

CSS Color
Web colors are colors used in displaying web pages on the World Wide Web, and the methods for describing and specifying those colors. Colors may be specified as an RGB triplet or in hexadecimal format (a ''hex triplet'') or according to their common English names in some cases. A color tool or other graphics software is often used to generate color values. In some uses, hexadecimal color codes are specified with notation using a leading number sign (#). A color is specified according to the intensity of its red, green and blue components, each represented by eight bits. Thus, there are 24 bits used to specify a web color within the sRGB gamut, and 16,777,216 colors that may be so specified. Colors outside the sRGB gamut can be specified in Cascading Style Sheets by making one or more of the red, green and blue components negative or greater than 100%, so the color space is theoretically an unbounded extrapolation of sRGB similar to scRGB. Specifying a non-sRGB color this way req ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
