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?

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.
(see Dr. Seuss) |
|
| |
there is no such problem in Chinese/Korean. They use the same character for both "green" and "blue". |
|
| |
//no such problem in Chinese/Korean. They use the same

|
| |
Really? makes you wonder if there was some kind of colour
blindness involved in those who developed their languages. |
|
| |
Ok, so maybe it doesn't make you wonder but it does me. |
|
| |
Huh possibly it seems <link> "Green blue color blindness
Tritanomaly occurs when the S-cones (short wavelength cones)
of the eye are present but dysfunctional. If you have
tritanomaly, blue and green will look alike, and red and
yellow will look alike. Tritanopia occurs when the S-cones of
the eye are missing, which causes colors to look dampened" |
|
| |
So
is there perhaps a higher incidence of that in China & Korea? |
|
| |
Did you see [xaviergisz] link? |
|
| |
Perhaps just the way language
develops, words only get added as particular need for one
arises perhaps. |
|
| |

paint colour] |

//colour blindness involved in those who developed their

|
| |
There seems to be a general phenomenon whereby older
languages have fewer colour words - or, at least, fewer
words for what we think of as different colours. |
|
| |
The Welsh word "glas" is ambiguous between blue and
green, and there's a word in Homeric Greek (I now forget
what it is) which is ambiguous between red and yellow. |
|
| |
This makes sense if it is connected with tritanopia, but
might also just be down to what [skewed] said. |
|
| |
// There seems to be a general phenomenon whereby older

|
| |
Yes [xaviergisz] already linked an article on that //what
[skewed] said// was in reference to it :) |
|
| |
I find it really weird that some languages don't have the
"blue/green" distinction. To me, at least (& I'm not a
tetrachromat or anything special), the sky and tree leaves are
blatantly different colours, so how do they end up with the
same word? |
|
| |
Me too, or fascinating at least, often the same thing that I
suppose. |
|
| |
Want to bet a correlation can be found with the
discovery or
prevalence of
cloth dyes & the appearance of new words in a language to
name their colour? |
|
| |
//Did you see [xaviergisz] link?// |
|
| |
I have now.
Okay sort of off topic but only tangentially, all legends have some kernel of truth at their core. Almost all religions refer to a great flood and the offer of a rainbow to solidify the deal that it wouldn't happen again. |
|
| |
What if humans were merely colour-blind at one time and a rainbow was just unable to be seen? |
|
| |
We just didn't have the eyes to see, the ears to hear... then. |
|
| |
//refer to a great flood//
My theory (citation needed...) is that, quite simply, water is
important for life. Therefore, all villages, towns, etc are built
near water (river, lake, ocean); & so floods are a Thing that
happens. Big flood = big problem, & becomes part of the
"shared history" that everyone can relate to. |
