Selective yellow
A yellow defined for car headlamps and fog lamps to cut glare in bad weather
Selective yellow is a strong orange-yellow used in automotive lamps, especially headlamps and fog lamps. It is designed to filter out blue and violet light, which can cause glare and discomfort in rain, fog, or snow. Once required for all vehicle headlamps in France, it remains permitted in parts of Europe and countries like Japan and New Zealand.

What colour is Selective yellow?
Selective yellow is a strong, orange-leaning yellow set by international standards for use in car headlamps and fog lamps. It is not a natural pigment or dye, but a colour defined by its effect on light. The main feature is its ability to filter out blue and violet wavelengths, which are said to cause glare and make it harder to see in rain, fog, or snow. This colour is so pure that it cannot be exactly shown on most digital screens.
Where does Selective yellow come from?
The name 'selective yellow' comes from its purpose: to selectively filter out certain wavelengths of light. It was created for road safety, not from a natural source or traditional craft. France once made it mandatory for all vehicle headlamps, and international regulations have defined its precise colour in technical terms.
How Selective yellow is defined
Selective yellow is achieved by filtering out the blue and violet parts of a lamp's light, usually with coloured glass or filters. The exact shade is defined in the CIE 1931 colour space, and is not based on a pigment or dye. The process can reduce the total light output by about 15%, but this is said to be balanced by better visibility in poor weather.
Where Selective yellow is used
This colour is mainly seen in automotive lighting, especially in headlamps and fog lamps. It was once required for all vehicles in France and is still allowed in Europe for older cars, as well as in Japan and New Zealand. Selective yellow is used to help drivers see better in bad weather by reducing glare.
What Selective yellow means
Selective yellow does not have traditional symbolic meanings. Its purpose is practical: to improve road safety by making it easier to see in poor weather. Studies have found it can reduce glare and, in some cases, slightly improve visual clarity compared to white headlamps.
