Why are some street signs blue?

I don’t understand why some street signs are blue when most of them are green, white, or yellow. Why would we make blue street signs?

The reason that street signs are different colors is that different street signs mean different things. Blue street signs are used to indicate services you can find along the roadway, including hospitals, restaurants, gas stations, hotels, and rest stops.
You don’t always have to pay attention to these signs, but they can be helpful on a
road trip
since you may find yourself on long stretches of highway without places to stop. With these signs, you can find what you need without actually pulling off the road.
While you’re learning more about road signs, why not learn about your insurance options, too? The
