The Earth is BLUE 🙂
Or at least this results from the following image of our own Moon: an extremely processed image (way to processed in my opinion, but the result is important) of the HDR multi-exposure method (8 sets of 10 to 40 images each, with different exposures of 4 seconds to 1/250s at constant aperture and ISO). To see different versions, I’m also posting the unsaturated image, and a more normal exposed image (what we actually see through a telescope).
Of course, the blue in the Earthshine (the part of the Moon not illuminated by the Sun) is due to the reflexion of sunlight from the Earth’s atmosphere/oceans which hits the Moon, and it’s reflected back at the Earth to be seen again by us. So it is a “double-reflected sunlight” 🙂
The colors on the Sun-illuminated part of the Moon are due to minerals at the Moon surface, which are actually there but can’t be seen with the human eye. Only when extreme processing is involved (like I did here) those colors start to be apparent.
