We are buying a small condo. In the living room one of the wall color is a bit lighter than navy blue. I am bringing a L-shape leather grayish green. The rest of the walls and sheer curtains are white. I am scare that the wall is too strong for my sofa even if it's a very big one 13 by 8. What other color could I paint it? The rooms are all open. It's a rectangle room. Living room and dining room. Big windows and open to the rectangle is an all white kitchen. It's my first time playing with dark color and I am not sure about it. I am usually very neutral. With that sofa the wall color at my present place are everywhere Wordly Gray. I also have a big colorful painting that I would like to put for the opposite wall but has not even a touch of blue in it. Can I do it? Help!
