Light Observation Outdoor

I went outside during the snow and observed the light. I'm from DC and I enjoy being outside in the snow because it is so much more beautiful at night. The way the light is trapped and reflects off the snow and illuminates the night sky. There's a special brightness that comes from the snow, I'm not sure how to describe it, but the snow somehow makes the night sky go from black to a darkish purple. There wasn't any extreme darkness to be found except under cars and in snowless corners of buildings.
