Snow is precipitation in the form of crystalline water ice, consisting of a multitude of snowflakes. Since it is composed of small rough particles it is a granular material. It has an open and therefore soft structure, unless packed by external pressure.
Snow is commonly formed when water vapor undergoes deposition high in the atmosphere at a temperature of less than 0°C (32°F), and then falls to the ground. It can also be produced by hoar frost which falls from the surface on which it is formed, or falling particles of ice fog formed when the humidity in surface air freezes at very low temperatures. Snow is less dense than rain, which means the same amount of moisture will produce a greater volume of snow than it will rain. One rule of thumb is that the water in eight units of snow is equivalent to one unit of rain. See Snow density

only pure water is colourless,snow is water that has frozen and in the process becomes cryatalized.these crystals act as prisims and combines all the colors in the light spectrum and therefore look white.As you know ,white is really not a color but a combination of all colors.

Snow is made of ice, which is frozen water in crystalized form. The angled sides of the crystals which make up the snow, reflect light, thus making snow white.

Actually water becomes less dense when it freezes thats why ice floats. When water freezes into small flakes the water crystalizes creating many angles of diffraction, so the light cannot penetrate it gets reflected giving the look of being white.

Since water is clear when it freezes the componants actually collect together making it denser. Because it's denser it's now not clear but opaque. Snow is opaque, just looks white.
Kinda like a polar bear. It's fur is actually clear but looks white.

Snow is white because it reflects all visible light equally. Water has no color because, although it refracts light somewhat, it does not refract any visible wavelength enough for us to see it, so we see what is "behind" the water instead.

Because if it was coloured, it wouldnt macth the background scenery.
Just think, pink snow on your backyard??? Green pure water after excercise???
Its God's sense of fashion that rocks!!!
