A spectrum of blue

When winter is upon us in full swing, shades of blue dominate in the polar circles, causing the days to feel shorter and nights to feel longer. The phase during which the sun goes below the horizon and hues of blue engulf the landscape, is known as blue hour. Its length varies based on latitude and season. Keep your camera ready as blue hour makes for an attractive opportunity for photographers.
