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.

Actually daylight 24/7 is a bad thing for a human. We are 
designed with night and day in mind. And our internal 
clocks  can be screwed up pretty bad with continuous 
illuminated conditions.
