Just the lamp in the corner. There is also a light above the mantle that points directly at the fireplace wall - it gives off a soft yellow light

Do have any textiles planned? Curtains / rugs / pillows / etc? I would choose those first, and then select a background color for your walls.

No rugs. The carpet is white and we are going with a light gray Roller shade or drapes.

I am thinking of going with navy blue Throws

I don't believe that's enough light. You need ambient, task and accent lighting, and you only have two of the three, and they sound/look to be inadequate. Paint is the last item chosen in a decor scheme. It must work with the fabrics and textiles which are set in stone. Paint color can be custom blended to work with those. Since your sofas are neutral, what other colors will you use in your space? Once you narrow down your choices, order big peel and stick samples from samplize.com so you can move them around to all walls, in all light/weather conditions to be sure of what you'll see once you've painted.

I would opt for more lamps for the most pleasing light, and would choose something with color for the walls. I prefer spaces that are cheerful rather than ” cloudy ”. Grays will make your room look washed out. Is your furniture gray? If so, choosing the right color will be more difficult. Maybe white walls and white drapery panels, and then add color with throws and pillows. I would avoid all blues unless it is a bright blue. No navy.

Here is an option for your room.

I see a wood end table. In sunlight, mine are pretty. Nice with wood floors... flared shade, amber glass, alternating pattern, which creates a zigzag effect.

I would leave wall as they are. Balboa Mist is nice warm color. So bring more colors with wall art.
Monochromatic
