The coloramber is a purechroma color, located on thecolor wheel midway between the colors ofyellow andorange. The color name is derived from the material also known asamber, which is commonly found in a range of yellow-orange-brown-red colors; likewise, as a color,amber can refer to a range of yellow-orange colors. InEnglish, the first recorded use of the term as a color name, rather than a reference to the specific substance, was in 1500.[1]

Amber is one of several technically defined colors used inautomotive signal lamps. In North America,SAE standard J578 governs thecolorimetry of vehicle lights,[2] while outside North America the internationalized EuropeanECE regulations hold force.[3] Both standards designate a range of orange-yellow hues in theCIE color space as "amber".

In the past, the ECE amber definition was more restrictive than the SAE definition, but the current ECE definition is identical to the more permissive SAE standard. The SAE formally uses the term "yellow amber", though the color is most often referred to as "yellow". This is not the same asselective yellow, a color used in some fog lamps andheadlamps.

Formal definitions

[edit]

Previously,ECE amber was defined according to the 1968 Convention on Road Traffic,[4] as follows:

Limit towards greeny0.429{\displaystyle y\leq 0.429}
Limit towards redy0.398{\displaystyle y\geq 0.398}
Limit towards whitez0.007{\displaystyle z\leq 0.007}

Recent revisions to the ECE regulations have alignedECE Amber withSAE Yellow, defined as follows:

Limit towards greenyx0.120{\displaystyle y\leq x-0.120}
Limit towards redy0.390{\displaystyle y\geq 0.390}
Limit towards whitey0.7900.670x{\displaystyle y\geq 0.790-0.670x}

The entirety[clarification needed] of these definitions lie outside thegamut of thesRGB color space — such a pure color cannot be represented using RGB primaries. The color box shown above is a desaturated approximation, produced by taking thecentroid of the standard definition and moving it towards the D65white point, until it meets the sRGB gamut triangle.[citation needed]

Lighting

[edit]

Thecolor temperature ofLED lamps is called amber when their wavelengths are about 590 nm. Chronomatic low-pressuresodium-vapor lamps emit light ranging from 580 to 590 nm.
