What color are the markings used for taxiways?

Taxiway markings are standardized to ensure consistency and safety in air traffic operations. The correct color for taxiway markings is yellow. Yellow is used to indicate the edge of taxiways, and it is one of the primary colors in aviation for transient or static guidance on the ground.

Yellow markings are easily visible against the natural background of the airport and help pilots navigate safely from taxiways to runways and other areas of the airport. They are particularly effective during various weather conditions, making them a practical choice for enhancing visibility in ground operations.

In contrast, red lines are typically used for identifying areas that are restricted or not to be entered, while green markings are often used for airport service roads. Blue lines are used to identify parking spaces for aircraft. This system of color coding serves to minimize confusion and maintain safety by providing clear directional cues to pilots on the ground.
