Usually we see the moon as a monochromatic world only with releif and albedo features to observe, but there is something on the surface hidden to the naked eye that everyone can capture with a digital camera, or just plain analog film. If you observe some particular features on the lunar surface through a telescope you will notice for sure some tiny differences in the hues of the various greys of the surface, as there are many different geological formations composed of different minerals, so there must be a difference, even though very subtle to our eyes, in the color. But to digital and analogic image capture devices it is an easy task to record color information with quite good accuracy, so it can be enhanced afterwords by digital processing to allow us to see it too!
