My 15” MBA is in midnight and it gets marked incredibly easily with greasy finger marks, but is quickly cleaned with a microfiber cloth. I ended putting a case on ours, however the keyboard deck still needs regular cleaning, but then that is the case for all laptops. The microfiber cloth I keep handy keeps the keyboard, trackpad and deck clean. I have no scrapes or scratches due to connectors or watch straps, so the midnight color seems to be perfectly viable and no worse or better than the silver or space gray I have had in the past.
