"And then you see beautiful light-blue streaks across Mercury's surface. Those are crater rays formed in impacts when fresh, ground-up rock is strewn across the surface of the planet," Plus I read a while ago this picture was taken by a camera that highlights the colours red and blue better than we would see them, If we went to mercury it would look brown to the eye.
