It’s a common misconception that the sky is blue because it reflects the blue of the seas and oceans. In fact, it’s the Earth’s atmosphere and a process known as 'scattering', that causes our skies to be blue.
As white light passes through our atmosphere, tiny air molecules cause it to ‘scatter’.
The scattering caused by these tiny air molecules,known as Rayleigh scatteringincreases as the wavelength of light decreases. Violet and blue light have the shortest wavelengths and red light has the longest.
Therefore, blue light is scattered more than red light and the sky appears blue during the day.
What’s going on… It’s all over the news. |

It's also why the sky goes red at sunrise/sunset. The sun is lower on the horizon and being scattered by larger particles that are lower in the atmosphere.
I had to explain the blue sky science to my daughters teacher once. |

"Another random fact - did you know it's also the most streamed song by the Beetles?"

So what’s that funny yellow thing I see occasionally? It’s always in a different place but I’ve only seen it twice this year. |

Whilst Mr Blue Sky by ELO (not The Beatles) is often played on the radio as a stand alone piece and was released as a single.
It actually forms the 4th and final track of the Concerto for a Rainy Day.
Which really should be listened to as a complete suite. |

What you see is reflected light, a colour blind person would disagree that the sky is blue. |

If it looks blue then it is blue. If it looks red, it’s red. That’s what I say. Also the sky doesn’t really exist either but that’s a whole other point. |

Just realised this sounds conspiracy theory-ish ha. I meant the sky isn’t a tangible thing, it’s just an illusion caused by the atmosphere |

I vaguely recall seeing one many moons ago, but thought it might have been a dream.......
