The solar system, which is largely empty space, would appear overwhelmingly black to an observer outside Earth. There is dust in the solar system, mostly in the plane of the ecliptic, which scatters small amounts of sunlight, and is sometimes visible from Earth at night (zodiacal light, or Gegenschein). During the day the sky appears blue owing to Rayleigh scattering but this effect is limited to our sky and would not be visible outside the atmosphere.
One could say some objects inside the solar system have a blue color as seen from space; Earth, Uranus, Neptune, and some moons.
