The images combine infrared, red, and green wavelengths of light to form a false-color image that distinguishes between muddy water and land. Water is blue. Buildings and paved surfaces appear in shades of blue-gray. Fallow fields appear in shades of beige and brown. Vegetation is red, and the brighter the red, the more robust the vegetation. (Brighter shades of red in March and duller shades in January result largely from the difference in season.)
