I've been recording the color of the sky as seen by various webcams around the world every few minutes.

Click on any lightwave to see the view from the webcam it uses.

Akureyri, northern Iceland (65.679236,-18.092446)

Akureyri is fairly far up north, so we can see a rather pronounced curvature here, indicating short days in winter and long days in summer. The most striking feature of this particular image though is how often the weather is gray in Akureyri — barely ever a blue sky.

The slightly darker patches such as the one that covers all of December, are caused by the camera's white balance shifting automatically when the ground was covered in snow (I think).

Alta, Norway (69.95592,23.373551)

Even further nordth than Akureyri, Alta sees a midnight sun in summer:

Alta, Norway (looking at the ground) (69.95592,23.373551)
Chatham, Virginia (36.84346008,-79.47482300)

Not a very good webcam in terms of colour quality, but I include it nonetheless because it's where I live. It tends to show she sky as white even when it's rather blue, though.

Hampden Sydney, Virginia (37.243752,-78.458251)

Nice colours here.

Miramar Beach, Florida (30.3693,-86.329494)

In this one you can see the moon as blurred whitish lines going down diagonally.

Templeton, New Zealand (-43.5,172.4)

Amazing image quality on this one, I find.

Universidad de Chile, Santiago (-33.457173,-70.661789)

My personal favourite. The image quality is amazing, the colours are beautiful, and you can see the moon passing through once a month. And you can also see that the weather in Santiago is ridiculously good in thr summer, and quite gray in the winter.
