Technically the sun is a yellow-white dwarf G2V. It
radiates in the whole visible spectrum, as well as the
infrared, ultraviolet and X-ray bands... So technically
the "light" that is emited by the sun, light being the
human visible spectrum, is white since it has all its
chromatic components... scattering and absorbtion however
may modify the actual color we end up seeing.
That being said, humans tend to fare better with "warmer"
lighting such as yellowish/redish... rather than "colder"
lights such as blueish. Whether it is a psychological or
physiological factor I have no idea.
