Why is the moon BLUE ?

Why does our moon image via Japan and China as though so unusually
deep blue color saturated, as having been accomplished with some of
the very best CCD cameras outfitted with the finest of optics and
sharp cutoff of bandpass filtering for entirely excluding those UV-a
and IR spectrums, and even to some extent moderating the violet hue
worth of raw solar illumination?
