Balanchine Crater (EDM - Absolute Natural Colors; credts for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)

The Impact Crater visible at the center of this scene (such as the one whose Floor is largely covered by extremely bright - and therefore, here, slightly over-exposed - Hollows) has been named "Balanchine", after the choreographer George Balanchine (Leningrad, 1904/New York City - NY - 1983). Now, if you carefully take a look at the Ejecta Blanket which emanates from Balanchine Crater, you may ask yourself what could have caused such an Asymmetric Pattern. Obviously, no one can give an absolutely definitive answer to this kind of question, as you should know, but a reasonable possibility is that the irregularly shaped Ejecta Pattern of Balanchine Crater formed (perhaps just in part) on top of a similarly sized, and pre-existing, Impact Crater.
In this scenario, the older Impact Crater could have unearthed the Lower Reflectance dark-gray Deposit (which, by the way, appear blue in the Original NASA false color image-mosaic) from beneath the Surface, while, some time (perhaps a few millions of years) afterwards, a certain portion of them was (unevenly) redistributed all over the Mercurian Surface by the impact that formed Balanchine.

This picture (which is a crop taken from an Original NASA - MESSENGER Spacecraft Map Projected false color image-mosaic published on the NASA - Planetary Photojournal with the ID n. PIA 17057) has been additionally processed, contrast enhanced, magnified and then re-colorized in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - MESSENGER Spacecraft and then looked down, towards the Surface of Mercury), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team. Different colors, as well as different shades of the same color, mean, among other things, the existence of different Elements (Minerals) present on the Surface of Mercury, each having a different Albedo (---> Reflectivity) and Chemical Composition.
