Why: The AIM lists white and green for civilian land airports. White and yellow marks a water airport, and green, yellow, and white marks a heliport. Military airports add two quick white flashes.
Huh, didn't know that: The AIM warns pilots not to rely on the beacon alone to decide whether weather is VFR or IFR.
