Explanation:
The color of the sky is due to the scattering of sunlight by the Earth's atmosphere. The blue color of the sky is caused by the scattering of shorter-wavelength sunlight (blue and violet) by the atmosphere. In the absence of the atmosphere, the sky would appear dark, not white or pink.

Reason:
The atmosphere of Earth is made up of various gases, including nitrogen, oxygen, and small amounts of other gases. When sunlight enters the atmosphere, it interacts with these gases and particles. The shorter-wavelength blue and violet light is scattered more than the longer-wavelength red and orange light. This is because the blue and violet light has a shorter wavelength, which makes it more likely to interact with the gas molecules and scatter in all directions. This is known as Rayleigh scattering.

In the absence of the atmosphere:
In the absence of the atmosphere, there would be no gas molecules or particles to interact with the sunlight. Therefore, there would be no scattering of the light, and the sky would appear dark. The stars would still be visible, however, as they emit their own light.

Conclusion:
In conclusion, the color of the sky in the absence of the atmosphere would be dark, not white or pink. This is because the blue color of the sky is due to the scattering of sunlight by the Earth's atmosphere, which would not occur in the absence of the atmosphere.
