Starting with the bedroom suites...have your bedding selected. Choose a color that coordinates. You can accent the headboard walls with a darker color and carry that darker color into bathroom on the walls, or continue bedroom color and carry the accent color into your towels and shower curtain. I would paint kitchen and 2 dining room walls the same color, selecting a darker color for the drama in the dining room and contrast with your kitchen cupboards (such as your green color). The other walls in your living room, foyer and hallway, should be your neutral color such as a camel or warm gray. This neutral is bumping up against all of your other room colors. So, it will make a good transition from room to room. On the bold side, you could find a great wallpaper for the two walls in the dining room. Don't forget to play up your foyer with furniture for that first look impact. Selecting your bedding first, allows you to tweak your paint color and hue, and the darkness of your color. Enjoy.

There is contrast between the traditional furniture and the focal point of the floor which pops, draws attention. I would recover the sofas in cream colored soft fabric - suede. I would leave the curtains grey, and put down a large neutral area rug. The edges of the room would show the pattern of the floor. I would color the wall and add texture to it, but not too dark as the room will appear smaller. Add a picture and put a nice plant holder, large vase in the left corner of the room - an oriental-style vase. Or, a cream-stripe fabric on the sofas. You could go soft or bold in this room - depending on your taste.

How do you decorate your place, what kind of style, colors, and feelings? That will greatly influence the type of door you might want. Also, think of your budget, and whether you want to install it yourself or hire a professional (you don't need to tell us, just keep that in mind). Then look around Houzz, in the products page, they have lots of interior sliding doors and hinged ones, from elegant frosted glass in a dark wood frame, to rustic reclaimed wood planks. You may not want to purchase that exact model, but it might give you a better idea of what would fulfill your airflow needs without sacrificing style.

Perhaps a large round table might mean a rug is not at all necessary. It could be a metal tray table, or carved wood like Rebecca Mitchell Interiors illustrates. Ideas also to consider, using multiple tables can be found at http://www.houzz.com/multiple-coffee-tables. I also agree with comments above that some color is needed on the walls. You could then hang round mirrors, or an unusual curved shape like RMI shows above.
