love this blue velvet sofa. Could possibly work with your brown arm chairs if you wanted a bold pop of color. Also with pillows and a throw to break up all that blue it won't seem as intense. Though if you go this dark I think the walls need to be dark. Maybe a dark grey in the living room?
Colorful and comfortable looking living area. Nice large botanical on the wall and nice little useful built-in bookshelves or places to showcase accessories. Good bold colored accent pillows also.
