Forgive the stupid title it was all I could think of. And no I don't think this should be part of wibbles either.

Due to pollution in different areas of the world some of us have different coloured skies, and in a way this is just looking at how different areas of the world have different pollution levels.

My city has 1 million people in it and it's the second largest city in the UK if you didn't know. Thus there are lots of people using cars- more pollution. To make this worse Birmingham lies in a basin, trapping a lot of the thick smog here.
When it's cloudy at night, the street lamps light up the thick clouds above. What you find is a muddy orange sky. It can be scary and very interesting at the same time.


So, what colour is your sky?
