A particularly 'red/orange' sunset. This visual of the sun at sunset can be influenced by smoke or dust particles, which can contribute to the Rayleigh effect, which relates, in part, to the shorter wavelength of blue light which scatters further as the sun passes over a greater distance, whereas red and orange have longer wavelengths. This vibrant sunset was spotted over Lisbon, Portugal.
