| Mar 30, 2015 at 19:11 | comment | added | Jay | Ditto the question. In one sense you could say, "The sky can be any color you can imagine if it just had the right chemicals in it." But is that really true? Are there colors that are impossible because no chemicals that could give that color could actually be present in a planet's atmosphere? We might have to add criteria about temperature, atmospheric pressure, and so on. Maybe chemicals that could exist in the atmosphere of planet A would precipitate out as solids on planet B, etc. | |
| Mar 30, 2015 at 19:09 | comment | added | Jay | I don't see a need to identify who or what is doing the viewing. Color exists independently of the human eye. The simple proof is that we have build machines that can recognize different colors. Yes, known living creatures cannot perceive the full electromagnetic spectrum, so colors that one creature can distinguish may look the same to another, etc. In that sense the viewer is important. But I can say that Earth's sky is blue even if I am speaking to a colorblind person, and while he may not be able to picture it, he could write down the frequencies, etc. | |
| Mar 30, 2015 at 19:07 | comment | added | Jay | Hmm, what do you mean by a "neutral color"? In the most obvious example we have, human beings on Earth, we don't say that the sky is some indeterminate neutral color. We say it's blue. | |

| Mar 29, 2015 at 23:17 | comment | added | Leprechaun | This is actually a quite complex question. Air composition, gravity, all play a role... | |
| Mar 29, 2015 at 21:27 | comment | added | Aron | BTW. Green, could be Fluorine gas, as the sky colouring. Its a cousin to another sky colouring called Chorine gas, very popular during the 20s in Europe. | |

| Mar 29, 2015 at 21:20 | comment | added | user3652621 | Haha, care to turn that into a full answer? | |
| Mar 29, 2015 at 21:18 | comment | added | Aron | Oh...thats simple then...it can be any colour you want, just add the right sky colouring. I hear grey is very popular in China right now. | |
| Mar 29, 2015 at 21:17 | comment | added | user3652621 | I'd have to assume human-like retinas and neural color processing. | |
| Mar 29, 2015 at 21:17 | comment | added | Aron | Important clarification, coloured, when which species is looking? For any home species the sky would have a neutral colour (but more blue from Rayleigh Scattering, and more red at sunset due to Mie Scattering). | |
