Selective Yellow Color 862 - #FFBA00

Selective yellow is a colour for automotive lamps. Under ECE regulations, headlamps were formerly permitted to be either white or selective yellow - in France, selective yellow was mandatory for all vehicles' road-illumination lamps until 1993.

The intent of selective yellow is to improve vision by removing short, blue to violet wavelengths from the projected light. These wavelengths are difficult for the human visual system to process properly, and they cause perceived dazzle and glare effects in rain, fog and snow. Removing the blue-violet portion of a lamp's output to obtain selective yellow light can entail filter losses of around 15%, though the effect of this reduction is mitigated or countervailed by the increased visual acuity available with yellow rather than white light in bad weather.
