The sky appears blue when viewed from Earth because of scattering of light particles I.e blue light gets refracted wherever there is atmosphere. As there is no atmosphere in space, astronauts see the actual colour of sky I.e black.

Sky appears black to an astronaut because there is no atmosphere in space and so there are no particles to disperse light from the sun. because there is no atmosphere to scatter light in the space. Because the sky is blue to us by the light being scattered through nitrogen.

The sky appears blue from earth because the light from the sun gets scattered by the dust particles and water vapor present in the earth's atmosphere and among all the light rays of different wavelengths present in polychromatic sunlight, the blue light scatters the most. In outer space atmosphere is absent and hence such scattering doesn't occur. Thus the outer space appears dark to an astronaut in space. read less

It's because the astronauts are above the earth's atmosphere and hence the light does not get scattered as it gets scattered as seen from under the atmosphere. So the astronauts see black sky.

the colour of the the sky depends on viewer angle. the blue sky is due to scattering of light. scattered light moves towards earth not above .... so astronauts can not see blue sky ..

Just one point: black is not a Colorado, it is the absence of light.
