Why is Snow white?

 Each snowflake may look as if it is white as it falls from the sky. In fact, the ice crystals are translucent, which means that they allow some light to pass through them. The sides of the snowflakes diffuse (spread out) the light which passes through them, so all the colours in the light reflect off the crystals. This makes the snowflake appear white.
