That depends on the color space.

In sRGB (whitepoint = D65 = ~6500K), the sun is a pale yellow.

In Wide Gamut RGB (Whitepoint = D50 = ~5000K), the sun is actually a 
pale blue.

If you use a color space with the equal-energy point (E) as whitepoint, 
the sun is even a pale green.


That's both for the sun's /actual/ color (without atmospheric effects, 
i.e. as seen from space) of ~5900K, as well as the sun's apparent color 
on earth at daytime of ~5500K.
