What is the colour of the sky?

What do you think it is?

I saw some comments from my parents the other day about the colour of the sky here. It is always blue and it is always pretty clear when it's clear.

So I decided to make an app that tracked it so I know what the colour of the sky is from where we are in the world.

Every day I'm aiming to take one photo of the sky (at around the same time of day).

Then I'm boiling down each photo to a single colour - kind of an average. The same for each week, month and year.

Check out the project page or the actual app page.
