Why is Snow White?

Snow Trivia: Have you ever wondered why snow is white?
The National Snow and Ice Data Center (NSIDC) of Colorado says: Visible sunlight is white. Most natural materials absorb some sunlight which gives them their color. Snow, however, reflects most of the sunlight. The complex structure of snow crystals results in countless tiny surfaces from which visible light is efficiently reflected. What little sunlight is absorbed by snow is absorbed uniformly over the wavelengths of visible light thus giving snow its white appearance.
