The skies were filled with a rare rose colour, which meteorologists at the Met Office have explained is due to sunlight passing through fine layers in the air, such as moisture or dust. Graham Madge, spokesperson for the Met Office, told the Daily Mail: When the sunlight comes through lots of layers, it filters out the blue and scatters it, leaving the red to come through, It's effectively a sunrise filtered through the atmosphere and through the fog, giving it that pinkish hue.
