Why does the sun look orange closer the horizon, but white in the sky?

During sunset, the light from the sun has to travel through a thicker slice of the atmosphere to reach your eye than it has to during midday.

As the white light from the setting sun travels through the atmosphere, red orange and yellow light is allowed to pass through with little interference.  But blue indigo and violet light is scattered more (which is why the sky is blue).  

Why are they scattering? Our atmosphere has Nitrogen and Oxygen molecules and these guys will scatter blue, indigo and violet.  

During sunset, the light is travelling through more of the atmosphere, so the scattering is more pronounced and you see red-orange sunsets.

If you were in space, it would still be white.
