The way we handle this in modeling various sci-fi subjects, is to take very thin sheet balsa or bass wood. The more flexible the better.
Cut the piece to the size of your planes flooring, and then add very watered down washes of watercolor, like yellow ochre, mixed with burnt sienna, and maybe a little burnt umber. Do not give it so many washes the you end up loosing your grain, but it'll look fantastic, and real all the way to 1/72 scale. Seal this with very thin coats of linseed oil, and allow to dry for a couple of days. It'll be gorgeous.
Hope this starts a new wave of ideas. Try it.
