Please explain, then, without using the word ‘sky’, what exactly you mean by “turning the sky green”.
I had parsed that as “ensuring that a person, looking upwards during the daytime and not seeing an intervening obstacle (such as a ceiling, an aeroplane, or a cloud) would honestly identify the colour that he sees as ‘green’.” It is now evident that this is not what you had meant by the phrase.
The only reason I see blue when I look up during the daytime at something higher than a ceiling, an airplane, or a cloud, is because the atmosphere is composed of reflective blue material (air) intervening between me and the darkness of space. I would still like an explanation from the great-great-grandparent as to what constitutes ‘turning the sky green’.

That would depend on whether a green shell of glass or a green particle counts as an intervening obstacle.
Do you know, I hadn’t even thought of that?
You are perfectly correct, and I thank you for raising the question.
