A picture speaks a thousand words! I’m embarrassed that someone else thought of posting one.accdd said:There are many solar power plants using large mirrors on earth. Their color as seen from the satellite is blue.

I have another question: if I have a photo of the sky taken with a smartphone, can I get physically meaningful data from the colors in the picture? Or can the RGB matrix I get cannot be used for anything?
I’d just add that a long trip up through the atmosphere would reduce the blue/green component and pull the resultant towards the original 6k(ish) white from the Sun.
My only question would be whether that image is actually from a satellite. I remember reading that a lot of the original Google images were in fact from surveillance aircraft
Plus the possible colour balancing of the Google images could have purposely biased the images to ‘look like’ we’re used to. But the point is more or less proved that what is seen up there is ‘a sky blue’.
