Related news. the dark surface of Mercury might be caused by carbon delivered by comets, so does this make Mercury a painted planet?

QUOTE
For this study, the team launched projectiles in the presence of sugar, a complex organic compound that mimics the organics in comet material. The heat of an impact burns the sugar up, releasing carbon.

Sugar on the dayside of Mercury would probably transform to a black carbon-rich crust, even without micro-meteorites.

Nevertheless the idea of comets as a source for carbon sounds reasonable.
