What color combination indicates a lighted landing airport?

A lighted landing airport is typically indicated by a combination of colors that serve specific purposes in aviation. The colors white and green are specifically used in the context of an airport's lighting system to clearly inform pilots about the location of an airport.

The green light signifies the approach end of a runway, while the white light may indicate runway edges or the runway itself. The combination of these colors ensures pilots can easily identify and verify the airport's location when approaching for landing, especially under low visibility conditions or at night.

In comparison, while other color combinations are used in aviation lighting, they do not typically denote a lighted landing airport. White and yellow may be involved in other lighting systems, but they do not specifically point to the designated runway approach lights. The red and blue combination is more associated with navigational hazards or aircraft lighting, rather than airport landing lights. Green and white lights might indicate an airport in certain contexts, but the standard combination recognized universally for lighted landing airports is notably white and green.
