Red rainbow
This picture shows predominantly red primary and secondary rainbows when the Sun (located behind the photographer) was very low in the sky, about eight minutes before sunset. When the Sun is near the horizon, the long pathway of light through the lower atmosphere scatters the shorter blue and green wavelengths of light. The remaining light is therefore proportionally higher in the longer wavelengths of yellow and red. Rainbows formed by this light lack the full spectrum of the “colours of the rainbow” and are predominantly red-coloured.

Red rainbow
This picture, taken in a rain shower near sunset in Hong Kong (China), shows the primary rainbow and a fainter secondary bow that are both predominantly red in colour. The bows lack the full colours of the spectrum because when the Sun is near the horizon, the shorter blue and green wavelengths of light are scattered by their long pathway through the atmosphere. The direct light rays forming the rainbow are therefore proportionally higher in the longer red wavelengths of light.

Red rainbow and anticrepuscular rays
In a rain shower near sunset, this primary rainbow forms a semicircle centred on the horizon directly opposite the setting Sun. The bow lacks the full colours of the spectrum because when the Sun is near the horizon, the shorter blue and green wavelengths of light are scattered by their long pathway through the atmosphere. The direct light rays forming the rainbow are therefore proportionally higher in the longer, red wavelengths of light.

Converging on the antisolar point (the point directly opposite the Sun) are dark streaks alternating with light beams. These are anticrepuscular rays.
