Decor ideas: I can't paint the walls....any other ideas?
The solution to a lot of wall space and no way to change the color is to fill the room in other ways. Focus on putting texture on the walls, but then carry that over to other areas.
Picture frames, art work, clocks, mirrors, and hung candles all work together to create a collage on the wall. Find similar color frames but different styles, then group your personal photos next to a clock or a mirror and so on. A good way to picture the layout of your wall is to place everything on the floor prior to hanging it.
If you have a strong color theme in your wall hangings, carry that over to your couch cushions. For example, if your wall art/frames has some strong blue tones, purchase throw pillows with that color in them. Add a lot of throw pillows to fill up your couch. The cluttered look will create a cozy feel. Be sure to have a blanket or two in the room as well.
Area rugs make a large, empty room cozy, even if you already have carpet. With white walls you can be as bold as you'd like, so pick a pattern such as this
Aria Ivory Circles area rug or this
Black Modern area rug . Area rugs work to separate a large empty room into a dedicated seating area.
Lighting is important in rooms with empty wall space. You can hang wall sconces that plug into the walls and don't need to be wired. Table lamps provide task lighting and a soft glow when watching TV.
Have fun!
Blue is a great accent color for dark brown and black, and so is red. Go
for a sea blue or a steel blue rather than a baby blue, and the combo
will look great. You can also add small touches of ivory to it, and it
will pull the colors together.
