So you like purple? Please buy soft lavender curtains, or some with purple printed flowers, I've had dark purple curtains in my old house (3meter high ceilings) and it looks really dark when they're closed. Add a purple sofa or lots of purple accents to keep it calm and friendly. You could paint the window wall a deep eggplant (not the other walls because of light) with creamy curtains.

This arrangement works much better, but some adjustments are needed to make it work. First, the fireplace grouping needs to be tightened. It crowds the dining area and you need a passageway behind the couch. Turn the rug lengthwise, parallel to the fireplace. Pull the large couch about 2 1/2 feet closer to the fireplace, and place the two chairs and loveseat on the ends of the rug, and pull them closer together. This will give you a more intimate conversation area, and not impose on the other areas of the room. Remove that floor lamp from behind the couch. If you need the light in that area, put it by the fireplace. Also, the stereo system on the mantel needs to find another home. Maybe it can go IN the fireplace instead. At the other end of the room, I think the arrangement would look better if the seating were rotated 90 degrees. Keep the rug and coffee table in its current configuration, place the sofa either facing the window or with its back to the window, and put the two chairs opposite it. Finally, the dining area. Now that you've moved the big leather chairs, you should have enough room. Your rug is too small. It should be big enough to give you at least a 2 ft. border all the way around when the chairs are pushed in. And it's a really beautiful table; please uncover it. I can't see what kind of lighting that area has. It really needs a pendant or chandelier hanging directly over the table.

Leather sofas can really dominate the room and can give an overall cold feeling. I would add some earthy elements, like a wood coffee table with glass or metal. Go to Restoration Hardware's website and look at their sofa room scenes. And I'm sorry I think the art is too harsh for the room. That's all your eye goes to in the room. too overpowering. I would look for something softer or maybe a cool mirror and I would add color to the room with pillows and some colorful lamps. I also think woven blinds would look great. They add warmth and give a finished look. The color of your window treatments should contrast your wall color a bit, not match it or else it starts to look generic and blah.. You have warm walls, warm floors and the woven blinds, like Hunter Douglas brand would pull it all together for you.

Either go with a darker shade for your woodwork or a lighter shade for the woodwork than the wall colors. I would use either the same color for all rooms or at least within the same color family. Each room will look different if you paint them all the same anyway due to light, time, of day and your furnishings. I like to choose the very lightest shade on a particular color spectrum. In other word a white with a hint of color. The ceilings do with a soft white or an off white. If you plan to place the TV above the fireplace a darker color will look good as an accent on that wall. If you have a narrow room try a darker color on the smallest wall to balance the size of the room. If your rooms are large try a very dark brown or navy or maroon as an accent wall. Have fun painting. Remember, if you don't like it, it's just paint and paint is cheap.
