Which option lists a color that is among the four basic general airport lighting colors?

• A. White
• B. Green
• C. Orange
• D. Black

Answer: (A)

Airport lighting uses a standard color palette so pilots can quickly interpret what they’re seeing. White is one of the basic colors in that standard set and is widely used on runways and in approach lighting to mark boundaries and paths. Orange and black aren’t part of the basic general airport lighting colors—black isn’t a light, and orange isn’t a standard color in the core lighting palette. Green appears in some lighting contexts as well, but the key point for this question is that white belongs to the familiar four-color set, making it the correct choice.
