I checked. It's not Rayleigh scattering (which accounts for the whiteness
of clouds) but Tyndall scattering. However, Rayleigh worked on Tyndall
scattering too, so it's loosely called Rayleigh scattering as well.
The cloud-is-white effect is also called Mie scattering.
It was Einstein who nailed down that N2 and O2 do the work, not dust and
The blue of blue eyes and bluejays is also Tyndall scattering.
The sky is not violet because (1) much violet is absorbed in the upper
atmosphere and (2) our eyes are less sensitive to violet.
