This first house was a rental in California, so I wasn't able to paint the walls. As a result, I had to use big blocks of color to break up the big white box! I was going through a divorce, so my house was a mix of pieces I owned and borrowed pieces from friends.
The red couch and black chairs, tables, etc. are tied together by the large red and black rug. The continuation of red and black pull the eye down into the dining room.
The same red couch (with a cover) in a house I owned. The first house was a very large house with cathedral ceilings in a California beach community. The second house is a much smaller Craftsman home in the Midwest - two very, very different styles of house with the same basic furniture.
Amazingly, the house came with the room painted that crazy school bus yellow paint. When I first saw the house, I said that I might be the only person in the world who had the absolute perfect furniture for that room!
This room is substantially smaller than the very open California house with the cathedral ceilings, but it still works in the space.
Because the dining room is painted brown, I went with a black and leopard rug to tie the rooms together.
You will notice that the side table is not black. I like mixing furniture so that not everything is "matchy-matchy". I have pulled the leopard into the room by adding a small leopard pillow.
