The silvery shimmer of a spring sky
Each place on earth has its own kind of light. Until I visited France, I didn't comprehend the nature of the light in French Impressionist paintings.
The appearance of the sky hints at latitude, location and climate zone. I grew up in Northern BC, where November brought cold weather and evening skies with a unique purple colouring that expressed the season: early winter in the North, but before the first snow.
The sky tells of the approach of snow too, for those who are interested and observant enough. A good nose also helps detect the season's first snow, perceptible as a scent in the air before blankets the ground.
