A librated, saturated moon

The "top right" bit of the moon on April 26th with the colour saturation enhanced by 500%. Maximum libration point was just beyond the 'sea' near the top centre, which means we can see slightly round the edge of the usual face of the moon. The 'sea' is Mare Humboldtianum. The moon seems to be muddy brown and electric blue, when you turn the colour up.
