What color are the lights at the beginning of the runway area?

The lights at the beginning of the runway area are indeed green. This is a standardized international aviation practice, as these green lights are designed to provide clear and distinctive guidance for pilots when approaching or starting their takeoff on a runway. The green lights indicate the edge of the runway threshold, helping in orientation and improving safety during takeoff and landing operations, especially in low-visibility conditions.

In contrast, other colors such as white are used for runway edges and centerlines, while blue typically indicates taxiway markings and amber is often associated with caution or warning signals in aviation lighting systems. The specificity of green lights at the runway threshold reinforces the importance of clear communication of critical information to pilots.
