Final answer:
Oranges and cats have no connection to the color of the sky, which is primarily blue due to atmospheric scattering of blue light.
Step-by-step explanation:
Oranges and cats are unrelated topics to the color of the sky. Oranges are a type of fruit and cats are a type of animal, while the color of the sky is a result of atmospheric scattering of sunlight. The color of the sky is primarily blue during the day due to the scattering of shorter-wavelength blue light by molecules in the Earth's atmosphere.
