Why are school buses yellow-orange (or yellow)?

Some facts about yellow:

Yellow (and the yellow family of colors) gets your attention faster than any other color. People notice yellow objects first.

Even when you are looking straight ahead, you can see a yellow object that is not in front of you "in the corners of your eyes" much sooner than any other color – even red. Scientists describe this as follows: "Lateral peripheral vision for detecting yellows is 1.24 times greater than for red."

Many experts also point out that colors such as yellow or greenish-yellow are more visible to the human eye under dimmer conditions compared to red.


Some facts about yellow cars, trucks and other moving vehicles




If  there’s fog or any kind of bad weather, drivers will still be able to see yellow cars or any moving vehicle fairly well.

Not only are school buses yellow, but also many earth-moving, road-building and other outdoor machines are yellow because you could get hurt if you accidentally run into one of them. Many accidents occur in farms and outdoors because the victim saw the moving object too late. If it’s yellow, you have a strong warning!
