The light of snow

I'm spending my evenings working through David Hornung's book COLOUR: a Workshop for Artists and designers. As I often point out, I am terrible at following directions so this morning when the weather station alarm woke me (-10C), I suddenly realised I had been mixing my chromatic greys/grays incorrectly and the first thing I did after taking pictures of the pink trees and the blue sky etc... was to re-do last night's assignment. 

I think I was primed from that and was about to work one of my ongoing projects when I noticed the snow light.  I found a canvas 5 X 7 and tried to record it. They say it will be snowy for a few days.  Beautiful light!
