Hi. Since you have such contemporary lines with the linear use of windows, I think your look is contemporary, but with so many windows, you still want a connection to the outdoors. My suggestion depends on whether you want to blend in with your surroundings, or make a statement. If you want to make a statement, I'd stay with a stark white, to contrast the sharp blue. Then use bluestone cut in a random pattern, to play off the blue roof, but keep an organic feel with the movement of the stone. If you want to blend in more with your area, then go with a mid-range gray color on the walls. It will tone down the contrast, and still stay contemporary. Not a dark charcoal, but not a dove gray. I attached a Gibraltar Gray from Lowes, or you might like a little lighter gray. Benjamin Moore has a bit softer gray: Cape May Cobblestone. Good luck! Please post your choices.

I think grays and blues would look great! here are a few accents that may go with your yellow color. I also think that if there are a few pops of bright yellow you would be ok! http://deciture.com/antique-styled-floral-wood-metal-wall-decor-3-assorted/ http://deciture.com/artistic-styled-metal-wall-decor-assorted/ http://deciture.com/attractive-styled-metal-flower-wall-decor/ http://deciture.com/peacock-in-print-wall-decor/

First of all, I don't think that furniture is comfortable enough to sit and watch TV, so the TV should be remove from that room, the purple wall paper and the purple furniture is too much, you should consider another color for that wall and the furniture against the wall it doesn't look good. What is that room at the end is kind of dark and I cannot appreciate exactly what is the purpose of that room. I'm a firm believer in skylights, we have skylights in the laundry room, kitchen, living room and office, they make a big difference. (if you cannot have skylights (or tube lights) can lights are a great option. There are a lot of great ideas from everyone. I can't wait to see the after photos.

if u like to paint the walls with light grey shade then it would be better to make the sofas white rather than a darker shade.
