November Twilight

Around this time of year when the weather is cloudless, the sky near the horizon turns a kind of clear turquoise, a greenish blue that fades into yellow closer to the earth. The weather is very clear but I suspect that the green sky is due to a lot of pollutants in the atmosphere that we don't see, such as mold or dust, and light has to pass through more of it near the edge than at a higher elevation. Also during these autumn twilights the trees are in black silhouette, even though in sunlight they are brilliant gold and red. The planet Venus shines in the sky to the West. This could be a real scene but I created it purely from memory.
