Make the sky green

Inspired by UnaBubba's "Paint everything green" idea, I propose that the sky be made green also; however, not using paint. Rather, by changing the properties of the atmosphere.

As far as I understand (link), the sky is blue because the different colours in white light are scattered differently by oxygen and nitrogen. So presumably adding some other gases in significant proportions will change the scattering properties, and so the colour will be changed. I'm thinking green.

Why is the sky blue? http://www.why-is-t...s-the-sky-blue.html

       oh help, everything has gone green. I can't see where I am going. whoops, oh no even the dog is green. was that the budgy I just stepped on? not only that, I have just been sick. don't ask about the colour. I said don't ask!

       Move to Gary, Indiana. At certain smoggy times the sky there is nice and green.

       Add enough yellow sulfur to the air, and you'll get a nice green hue. 'Course you probably won't be able to breathe... but you can't have it all, can you?

       I have seen green skies and usually it's a sign that you should be indoors. I've heard that, in certain midwestern states, it's a sign that you should be indoors and probably in a cellar.

       Yes, [bristolz], that seems to be true. There was once a tornado that went through this area when my father was just a small child. Extremely rare occurence for Michigan - but the whole afternoon everyone was talking about how strangely green the sky was.

       There is a slight problem though. Since sunlight is (from an energy per color point of view) is green, our eyes are less sensitive to it.   

       Blue is an easier colour.

       Confusing to pilots. Years of tuition and study go into learning that blue is up, green is down.

       But think of all the bad poetry we'd have to change.   

       (Fishy for you. Maybe if you had said brown instead of green...)

       Another popular choice for green gases is Chlorine... Not a very healthy option either.

       wouldnt that be nice, all green. i love the color green, like in plants. all the pretty green trees and grass.   

       it would kill all the plants, turning the sky green. you know plants look green because they reflect the green light from the sun and use the rest for photosynthasis. with only green light they'd have no light to use and die of starvation. But we wouldnt need them to green things up if the sky where green.   

       so go ahead and sulfer/chlorine the air to make things green, because you'd die from the CO2 before anything else.

       No! If the sky were green, how would I know where to quit mowing?

       One word: Oobleck.

       there is no such problem in Chinese/Korean. They use the same character for both "green" and "blue".
