Deeper, I would simply say that the sky is blue because air is blue. You cite Rayleigh scattering, but you’re just describing how light interacts with air. The only reason any material has any color is because how it interacts with light.
Air is blue. You can explain its blueness just like you can the physics origin of any other object’s color. But ultimately the sky is blue because air is blue.
Probably not strictly translatable to all other colors, but a helpful illustration of how color is a result of the way objects interact with light, not inherent properties of the object itself.

Steve Mould has a great video digging into why things look white: https://www.youtube.com/watch?v=gug67f1_8jM
