Sure it's blue, provided the atmosphere has oxygen and nitrogen in it.
Sunlight is quite white (= a uniform mixture of all spectral colors).
The long-wavelength component, however, is scattered by the atmosphere,
making it appear to come from all directions evenly, leaving what's
visible in the direction of the sun somewhat yellow.

Hence the following sappy ballad (MIT version):

	Tell me why the stars do shine,
	Tell me why the ivy twines,
	Tell me why the sky's so blue,
	And I will tell you just why I love you.

	Nuclear fusion makes stars to shine,
	Tropism makes the ivy twine,
	Scattering makes the sky so blue,
	Gonadal hormones are why I love you.

No man is an island, entire of itself; every man is a piece of the
continent, a part of the main.  If a clod be washed away by the sea,
Europe is the less, as well as if a promontory were, as well as if a
manor of thy friends or of thine own were: any man's death diminishes me,
because I am involved in mankind, and therefore never send to know for
whom the bell tolls; it tolls for thee.  --John Donne
