Everyone has seen an ambulance, but why are they always either white or yellow?
Specifying a color scheme involves reasons revolving around safety and the ability to recognize the ambulance from a distance.
Ambulances are required by laws of many cities to be “conspicuous, bright and easily visible.” Choosing bright, prominent colors make the vehicle eye-catching and glaringly obvious. White is the most irradiant hue in the color palette. Yellow has great contrast with other shades like red and blue, which are commonly used. The distinct difference increases noticeability.
Having a regular, consistent designated color for emergency vehicles allows road users and the general public to spot ambulances quickly. Especially on the road and while on the move, if drivers can easily see that those yellow vans are surely ambulances, they are more likely to take note and give way to such emergency vehicles. Similarly, if the injured patient can easily sight and notice that a white van with bright flashing blue-red lights is an ambulance, then our casualty here can readily flag down and seek help from the onboard paramedics.
Color uniformity helps in identifying rescue workers and emergency ambulances. Singular color themes in each fixed city help its residents remember the color related to instant help and rescue. Therefore, yellow and white are chosen as the most effective colors for this identification task.
In the day, bright colors bounce light rays from the sun. These white and yellow vehicles can be seen from afar and across long distances.
As conventional wisdom says: it is risky to wear dark clothing at night as you blend into the night and become harder to see, increasing the probability of accidents. Having white ambulances reflect sunlight on a sunny day better than any other shade and hue, making it more visible for other drivers on the road.

Highlights, such as yellow and white, make roadside ambulatory work safer and more distinguishable. Such easily recognizable vehicles create a less risky clinical environment for first responders. Paramedics and ambulance medical crew who provide care to the critically ill casualty can operate in peace and relative safety.
In conclusion, the colors designated for ambulances are usually white or yellow because of the safety benefits and easy identification. In the pre-hospital and ambulatory field, our medical work involves being responsive and performing quick interventional first aid. Time is often of the essence, so white and yellow pigments surely complement this end.
