Winter Snow

I just love Winter, only when its full of snow though.
One of the reasons I love snow is because of how the sky changes. In the daylight its gray. But when it becomes night a entire new world appears. the sky isn't dark, it still has a hint of light, its like its own nightlight. The snow, like featherly flake falling from heaven its self, each different in shape and size.
Something I think would be awesome is if each snowflake was different in color. Just think of how many colors that would be, and what would the ground look like when it was filled with multi colors blended together.
But then again, the white, the pureness of snow. Why change it?
