Amber (color) 1168300 223469411 2008-07-04T05:41:52Z Keraunos 1439972 Add space. '''Amber''' is an [[orange (color)|orange]]-[[yellow]] [[color]] that got its name from the material known as [[amber]]. Due to this, amber can refer not to one but to a series of shades of orange (shown below in the ''shades of amber'' color comparison chart), since the natural material varies from nearly yellow when newer to orange or reddish-orange when older.

It is a color that is 75% yellow and 25% [[red]]. The first recorded use of ''amber'' as a color name in [[English language|English]] was in [[1500]]. <ref> Maerz and Paul ''A Dictionary of Color'' New York:1930--McGraw Hill Page 189; Color Sample of Amber: Page 43 Plate 10 Color Sample J3</ref> {{-}} ==Automotive lighting== {{infobox color| title=Amber (desaturated approximation)| hex=FF7E00| r=255|g=126|b= 0| c= 0|m= 50|y=100|k= 0| h= 30|s=100|v=100 |source=[[CIE 1931 color space|CIECD]]}} Amber is one of a handful of colors used in automotive signal lamps, and common standards are used to define these colors. In North America, the SAE, or [[Society of Automotive Engineers]], has its J578 standard,<ref>[http://www.sae.org/technical/standards/J578_200612 SAE J578: Color Specification]</ref> while European countries use the [[ECE regulations]] published by the U.N. Economic Commission for Europe.<ref>[http://www.unece.org/trans/main/wp29/wp29regs/r006r3e.pdf ECE R6]</ref> Both designate a range of orange and yellow hues in the [[CIE 1931 color space|CIE colorspace]] as "amber". The SAE formally uses the term "yellow amber" though the color is usually simply referred to as "amber". Amber should not be confused with [[selective yellow]], a different color used in fog lamps, and sometimes as headlights in some European countries. In the past, the ECE definition was more restrictive than the SAE definition, but more recently it has been aligned with the SAE standard. ===Formal definitions=== [[Image:Turnsignals On.jpg|thumb|left|A turn signal emitting amber light]] Previously, '''ECE amber''' was defined according to the 1968 Convention on Road Traffic<ref>{{PDFlink|[http://www.unece.org/trans/conventn/crt1968e.pdf ECE Convention on Road Traffic, 1968, p. 60]|163&nbsp;[[Kibibyte|KiB]]<!-- application/pdf, 167020 bytes -->}}</ref>, as follows: {| cellspacing="5" | Limit towards green | <math>y \le 0.429</math> |- | Limit towards red | <math> y \ge 0.398</math> |- | Limit towards white | <math> z \le 0.007</math> |} Recent revisions to the ECE regulations have aligned '''ECE Amber''' with '''SAE Yellow''', defined as follows: {| cellspacing="5" | Limit towards green | <math>y \le x - 0.120</math> |- | Limit towards red | <math>y \ge 0.390</math> |- | Limit towards white | <math>y \ge 0.790 - 0.670 x</math> |} The entirety of these definitions lie outside the [[gamut]] of the [[sRGB]] color space — such a pure color cannot be represented using RGB primaries. The color swatch to the right is a desaturated approximation, created by taking the [[centroid]] of the standard definition and moving it towards the D65 [[white point]], until it meets the sRGB gamut triangle. {{-}} ==Shades of amber color comparison chart== The purpose of the color comparison chart is, by arranging the shades of a particular color in approximate order from lightest at the top to most saturated in the middle to darkest at the bottom, to allow the Wikipedia user to more easily choose a color they may need for a particular use. Having the colors arranged by shade rather than alphabetically makes it easier to do this. <ul> <li style = "background-color: #ffcc00;"> Tangerine Yellow (Hex: #FFCC00) (RGB: 255, 204, 0)<li> <li style = "background-color: #ffc430;"> [[Saffron (color)|Saffron]] (Hex: #F4C430) (RGB: 244, 196, 48)</li> <li style = "background-color: #fcc200;"> Golden Poppy (Hex: #FCC200) (RGB: 252, 194, 0)</li> <li style = "background-color: #ffbf00;"> AMBER (Hex: #FFBF00) (RGB: 255, 191, 0)</li> <li style = "background-color: #ffba00;"> [[Selective yellow|Selective Yellow]] (Hex: #FFBA00) (RGB: 255, 186, 0)</li> <li style = "background-color: #ffb97b;"> Macaroni and Cheese (Crayola) (Hex: #FFB79B) (RGB: 255, 185, 123)</li> <li style = "background-color: #f4a460;"> Sandy Brown (web color) (Hex: #F4A460) (RGB: 244, 164, 96) <li> <li style = "background-color: #ff9966;"> Atomic Tangerine (Crayola) (Hex: #FF9966) (RGB: 255, 153, 102)</li> <li style = "background-color: #ef9b0f;"> [[Gamboge]] (Hex: #EF9B0F) (RGB: 239, 155, 15)</li> <li style = "background-color: #ff9933;"> [[Saffron (color)#Deep saffron|Deep Saffron]] (Hex: #FF9933) (RGB: 255, 153, 51)</li> <li style = "background-color: #ff7e00;"> UNECE Amber (Hex: #FF7E00) (RGB: 255, 126, 0)</li> </ul> ==Amber in human culture== '''[[Computer]]s''' * [[VT220]] computer terminals were available with amber colored characters on their [[CRT]]s. '''[[Interior Design]]''' * The original [[Amber Room]] in the [[Catherine Palace]] of [[Tsarskoye Selo]] near [[Saint Petersburg]] was a complete chamber decoration of [[amber]] panels backed with [[gold]] leaf and [[mirror]]s. Due to its singular beauty, it was sometimes dubbed the ''[[Eighth Wonder of the World]]''. '''[[Religion]]''' * The color amber is associated with [[Zoroastrianism]] because of its practice of [[fire worship]] in [[fire temple]]s (actually, the [[holy]] fire is simply a representation of the [[spiritual energy]] of [[God]] [ [[Ahura Mazda]] ] ). '''[[Sports]]''' * Amber is a color worn by [[Hull City AFC]], an English football team. This is to represent their club nickname of 'The Tigers' and in many kits is used with black. '''[[Symbol|Symbolism]]''' * Amber is a [[Symbolism|symbolic]] color representing [[energy]]. '''[[Transportation Planning]]''' * Amber is used in [[traffic light]]s and [[Automotive lighting|turn signals]]. ==References== <references/> ==External links== * [http://www.unece.org/trans/main/wp29/wp29regs/r006r3e.pdf UNECE Regulation No. 6: Uniform Provisions Concerning the Approval of Direction Indicators for Motor Vehicles and their Trailers (E/ECE/324-E/ECE/TRANS/505/Rev.1/Add.5/Rev.3/Amend.2)][http://www.unece.org/trans/main/wp29/wp29regs/6rv3am1e.pdf][http://www.unece.org/trans/main/wp29/wp29regs/6rv3am2e.pdf] * [http://www.unece.org/trans/main/wp29/wp29regs/r48r3e.pdf UNECE Regulation No. 48: Uniform Provisions Concerning the Approval of Vehicles with Regard to the Installation of Lighting and Light-Signalling Devices (E/ECE/324-E/ECE/TRANS/505/Rev.1/Add.47/Rev.3/Amend.2)] * [http://www.dialight.com/ledinfo.tpl?page=chromaticity Dialight: Transportation Chromaticity Standards] A manufacturer's page showing various color definitions on the CIE colorspace. {{Shades of orange}} {{Shades of yellow}} [[ca:Ambre (color)]] [[it:Ambra (colore)]] [[ja:橙色]] [[lt:Gintarinė]] [[nl:Amber (kleur)]] [[pl:Bursztyn (kolor)]] [[pt:Âmbar (cor)]] [[ru:Янтарный цвет]] [[simple:Amber (colour)]] [[vi:Hổ phách (màu)]]
