During sunset, what happens to the short-wavelength light relative to the observer's direct line of sight to the sun?

Answer

Almost all of the short-wavelength light (blue and violet) is scattered away from the direct line of sight

As sunlight travels the long path at sunset, the blue and violet light is scattered extensively away from the direct path, leaving the long wavelengths (red/orange) to dominate the beam reaching the observer.
