    Both come from Rayleigh scattering. Air scatters short blue wavelengths the most, so at noon blue reaches you from every direction. At sunset the light crosses far more air, the blue is scattered away, and red is what is left.

    Why sunsets are red

    Rayleigh scattering
    • Scattering ∝ 1/λ⁴, so blue scatters 5–6× more than red
    • Noon: short path, blue from everywhere
    • Sunset: long path, blue removed, red remains

    In my own words: the sky keeps the blue for itself
