Yes, the blue is beautiful with that wood. You can do as you've shown with an area rug to brighten the space and keep the brown from overpowering the wood and leather. I personally would never pick a black or brown leather sofa with that beautiful wood. I like the orange chair, but would probably select blue for it and bring in a second chair in an entirely different but complementary style, in a print incorporating blue and another color (orange if you like, or green, or ?). That leather does not look like a light sucking blue, but one that would make the room vibrant without being too bright.

Beautiful blue. You might try asking your questions in the Home Decorating forum. The Paint forum attracts more painting contractors than decorators. Good luck!

For visitors and when you come home, your house is going to be framed against the sky, which will change depending on the weather. But the sky will almost always be a cool color. So start from there. Personally, I like warm colors on homes as they contrast with the sky (bringing out the house) and are more welcoming. From the photo, it appears you are in a rather tightly packed neighborhood, so you want your paint scheme to be a positive for the neighborhood and the other houses...a little different but not crazy different. I notice that the popular colors in the Western U.S. are different from the Eastern U.S. Where do you live?

I have been living with the acorn color for two weeks now on my second floor. I am more traditional, like you are. The floor installer said he liked working with this product and the quality was excellent. It looks very nice and it is comfortable underfoot, easy to clean and doesn’t show dirt. The only thing that surprised me was that the actual product out of the box looks darker than the sample, but I do still like it.
