Hmmm. Going for sci-fi spaceship, my favorites tend to be more on the space-opera side than the realism side. I suppose the question is whether it's "what do you think the immediate future will look like" versus "what do you think the distant future should look like".

Generally speaking, I'd go for sliding interior doors rather than swinging, depending on cost/maintenance effectiveness, to give the feel of airtight compartments. I'd say white and silver with interesting curves, but I have nostalgic tastes in sci-fi. If we're going for more realistic/near future, keep things in cupboards/fastened to things so they wouldn't go flying around under sudden acceleration. (I realize that's a lost cause as soon as people move in.)

For anything more specific, I'd really want to know what exactly the Network Operations Center is doing. I figure either way, spaceships are going to be designed for a purpose, and mass is precious so everything needs to be doing its job.
