The moon does have color varience, but monochromatic shades of gray (though the depth of varience seems infinite).
I think what you have captured though is optics induced.
Possibly atmospheric though. As you go towards the limb, the reflectance is reduced, and if there is a haze, it will appear more apparent. The brighter part of the moon simply overwhelms it, but as you move into areas of less and less illunmination, if there is hase in the atmoshpere, it can show up.
Anyway, I doubt that this was the moon's coloration. And the more I consider it, the more I think it was atmospheric.
