What is the color of the taxiway center line?

The color of the taxiway center line is yellow. This is standardized in aviation to ensure that pilots have clear visual cues while maneuvering on the airport surface. Yellow is used for taxiway markings to denote the center line, which assists in guiding aircraft to and from runways and taxiways safely. The bright color stands out against the tarmac, providing high visibility even in varying weather conditions.

In contrast, white is typically used for runway markings, while red indicates areas that should not be entered. Green is not a standard color used for center lines on taxiways or runways, and its use is generally reserved for other specific markings within the airport environment. Thus, understanding these color conventions is essential for safe airport operations and navigation.
