Whatever you do, don't get a blue carpet, since all blue carpets fade - sooner or later. A soft grey would look good, or lavender if you want a slightly less stark colour scheme.
depends on the look you are aiming for cool modern, ethic, classic, me I'd go with a soft terra cotta, and maybe have one of the walls a deep terracotta shade and use bronze and dark wood accessories but I am quite brave..
A soft warm grey maybe with lime green and turquoise glass accessories with other reflective surfaces mirrors and silver and a few large plants if the room gets a lot of sun
weecalf funny you should say that I was thinking wooden floor but keep being put of that idea by people telling me how cold it is and rowan that sounds lovely
