Why is the sky blue?

https://explainers.blog/assets/img/sky/rayleigh-scattering-by-frequency-graph.png
The color of the sky is determined by the scattering of photons by small molecules in the atmosphere, with blue photons being scattered more than others due to their resonant frequency with nitrogen and oxygen molecules. The sky appears blue because of this scattering, and its color can change depending on the presence of other particles or gases in the atmosphere.
