I think navy/indigo might be too dark. I suggest that the blue you choose be based off the color of blue in the artwork and the blue vase on the floor. You will need a blue with a yellow instead of red undertone so it blends with the color of brown furniture you have and the yellow ottomans. You could go one or two shades darker. Paint patches both choices on each wall to find out how the colors look at different times of day/different lighting. If the blue seems "too bright," have the paint company add one drop of black to each gallon/4 liter/4 litre container.
