Have you ever noticed that snow is white until it melts?
Just like other things get their colour because of the way light works, so does snow! When light shines onto Earth, it shines a huge spectrum of energies that our eyes interpret as different colours. Snow and snowflakes are ice crystals mixed with air molecules. The air gaps between crystals, along with the complex shapes of the crystals, bounces the light beams around so much that all the wavelengths eventually get reflected out, giving it a white colour.
