What color lights indicate a taxiway at an airport?

Blue lights are used to indicate taxiways at an airport. These lights help pilots navigate the airport's surface safely while taxiing their aircraft. The blue color differentiates taxiways from runways, which are indicated by white lights. The use of distinct colors, such as blue for taxiways, enhances visibility and helps prevent confusion, allowing for safer ground operations. Understanding these color codes is essential for ramp agents and anyone involved in airport operations, ensuring they can assist effectively with aircraft movements on the ground.
