Rayleigh scattering
An atmospheric scattering mechanism caused by air molecules in which scattering intensity is inversely proportional to the fourth power of wavelength, scattering short-wavelength blue light more strongly; it is the physical basis for the blue color of a clear sky and the reddish tint of sunsets.

Real-time rendering often uses precomputed lookup tables (LUTs) to simplify Rayleigh and Mie atmospheric scattering calculations, sampling at runtime according to the sun angle and view direction.
Rayleigh scattering is caused by air molecules and scatters short wavelengths (blue light) far more strongly than long wavelengths (red light), with intensity inversely proportional to the fourth power of wavelength, which explains why the clear sky appears blue and sunsets appear reddish.
