What color indicates a safe departure from the centerline on a taxiway?

The color indicating a safe departure from the centerline on a taxiway is green. Typically, green markings are used to guide aircraft safely along the taxiway surface and confirm that they are on the correct path. This helps pilots maintain situational awareness and ensures safe movement while navigating the airport grounds.

In aviation, different colors serve specific purposes. While red often indicates restrictions or danger (such as stop bars or prohibited areas), yellow is more commonly associated with caution and highlighting the centerline or hold short lines. Blue is designated for parking areas and is used for informational purposes, rather than guiding departures from a centerline. Therefore, the use of green enhances clarity and safety when pilots are taxiing, making it the correct answer for indicating a safe departure from the centerline on a taxiway.
