In automotive lighting, UNECE Regulations state that direction-indicator lamps and standalone side-marker lamps and reflectors on vehicles must be amber. The color is defined in terms of the CIE 1931 color space 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 this definition lies 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.
