Yeah, I'm not sure exactly any words that have been used to describe it, and it might be a bit weird trying to put it into words in an IC post, so in short- stereotypical sci-fi style silvery-grey wall panels, dark flooring, very clean aesthetic, almost to the point of being unsettlingly sterile. The quarters and common area are meant to be a lot more homely, lit by smaller light fixtures like lamps rather than the large, bright ceiling lights used everywhere else in the ship. Synthetic wood finishing on the furniture and around the door frames, but in a classy way, know what I mean?
