My sofa is brown. Walls are light chocolate. Doors are a light green. Need color for ceiling other than white. Right? A light grey would look fabulous with the brown and the green: You could repeat the green in the same or different shade: Here is a brown room with blue on the ceiling and green in the adjacent room: Happy to hear you're putting color on the ceiling.

Embrace the arches and keep it light, but add some contrast. Paint every wall with an arch in it fresh white, all ceilings too. Paint the adjecent walls a soft color. For example; when you keep the kitchen tile, you could paint the walls above it a soft pink or mauve. I see three open areas, so you could divide those with three soft colors and white inbetween. Keep most lights simple and functional, uplights will enhance the arches, glass pendants will add warmth. And I think a soft olive or sage green is a great color for a living room.

Seriously ? TV's belong in living room if ever you have company coming over...even if they just come over for the holidays. Otherwise, TV belongs in the room you (and only you) spend the most time in. I can "see" a TV in a sunroom in where while you are enjoying the warmth and comfort (relaxing) in the Sun. Bliss

One option, I would get a very large rug so that all the chair legs and at least one corner of the sofa is on the rug. I think I would also bring the table set away from the window a little more. I think there is enough space to place the two-seater opposite the table in front of the window. or bring the table forward toward the kitchen ....... With the sofa centered to the large window. They probably will not be opposite each other, but at an angle which is still ok. They might seem more functional for the table set to be closer to the kitchen. Another option is two rugs in wide runners. Creating a walkway through the center of the room. Still thinking the sofa center of the right window. Just some ideas :-)
