Amber (color)

Amber (#FFBF00)

Amber is an 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.

Amber is one of several technically-defined colors used in automotive signal lamps. In North America, SAE standard J578 governs the colorimetry of vehicle lights,^[2] while outside North America the internationalized European ECE regulations hold force.^[3] Both standards designate a range of orange and yellow hues in the CIE colorspace 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 as selective yellow, a color used in some fog lamps and headlamps.

Formal definitions

A turn signal emitting amber light

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

Limit towards green	$y \le 0.429$
Limit towards red	$y \ge 0.398$
Limit towards white	$z \le 0.007$

Recent revisions to the ECE regulations have aligned ECE Amber with SAE Yellow, defined as follows:

Limit towards green	$y \le x - 0.120$
Limit towards red	$y \ge 0.390$
Limit towards white	$y \ge 0.790 - 0.670 x$

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.
