Is The Sun White or Yellow?

Ask a meteorologist “why is the sky blue?” and they will (at least they should) quickly give you the proper answer. The basics are this: shorter wavelengths of blue light are scattered by the air molecules much more than longer wavelengths of red light. The blue light gets scattered across the sky and makes the sky look blue. The technical term is Rayleigh scattering.
