   Explanation: [6]Only natural colors of the Moon in planet Earth's sky
   appear in this creative visual presentation. Arranged [7]as pixels in a
   framed image, the lunar disks were photographed at different times.
   Their varying hues are ultimately due to reflected sunlight affected by
   changing atmospheric conditions and the [8]alignment geometry of Moon,
   Earth, and Sun. Here, the darkest lunar disks are the [9]colors of
   earthshine. A description of earthshine, in terms of sunlight reflected
   by Earth's oceans illuminating the Moon's dark surface, was written
   over 500 years ago by Leonardo da Vinci. But stand farther back from
   your screen or just shift your gaze to the smaller versions of the
   image. You might also see one of da Vinci's most famous [10]works of
   art.
