The sky is red.

Infact verdict: Mostly True (70/100).

The sky generally appears blue due to Rayleigh scattering, but it can appear red during sunrise or sunset due to the scattering of longer wavelengths like red and orange. This phenomenon occurs because the sunlight passes through more atmosphere, scattering the shorter wavelengths and allowing the longer red wavelengths to dominate.

Mostly True Science
The sky is red.
While the sky is typically blue due to Rayleigh scattering, it can appear red during sunrise or sunset when the sun is low on the horizon. This occurs because shorter wavelengths are scattered out and the longer red wavelengths become more prominent.
