What will be the colour of sky if there is no atmosphere on the earth?...
Raleigh Scattering of light by the atmosphere is what causes "the sky" to appear blue (and sunsets to appear red), but that "sky" is a colour of the atmosphere. If there is no atmosphere, what colour is it?
Without the atmosphere there is nothing local to act as a (secondary) source of light, so there is no light and we conventionally call objects that emit (little or) no light "black". So the non-object that is "the sky" could be called "black".
If we consider all light from "the heavens" to be the colour of "the sky" then it is clearly not "black". Even with the atmosphere and nasty light pollution from cities, the Milky Way appears rather off-white. With an even grander view of the Universe, we are told it's overall shade is Cosmic Latte, but I would take that with a pinch of salt or, perhaps, a tint of grey when it comes to human perception.
My preferred word for the apparent colour of "the sky" would be transparent rather than "black", but a pedant could argue that "transparent" is not a colour...

What will be the colour of sky if there is no atmosphere on the earth?...
The color of the sky without an atmosphere on Earth would be black.
Explanation:
When we observe the sky on Earth, it appears to be blue during the day and black at night. This is due to the scattering of sunlight by the Earth's atmosphere. However, if there is no atmosphere, the color of the sky would change.
Scattering of Light:
When sunlight enters the Earth's atmosphere, it encounters molecules and particles present in the air. These molecules and particles scatter the sunlight in all directions. The scattering of light is more effective for shorter-wavelength light, such as blue and violet, compared to longer-wavelength light, such as red and orange.
As a result, the blue and violet light gets scattered in all directions by the molecules and particles in the atmosphere. This scattered light reaches our eyes from all parts of the sky, making it appear blue.
Color Without Atmosphere:
If there were no atmosphere on Earth, there would be no scattering of sunlight. As a result, the sky would not appear blue during the day. Instead, it would be dark, similar to what we observe at night.
Without the atmosphere to scatter sunlight, the only source of light in the sky would be the stars and other celestial objects. Therefore, the sky would appear black, just like the color we perceive during the night when there is no sunlight to illuminate the atmosphere.
Conclusion:
In the absence of an atmosphere on Earth, the color of the sky would be black. The scattering of sunlight by the Earth's atmosphere is responsible for the blue color of the sky we observe during the day.
