Can't go wrong with a simple white - it'll brighten up the room instantly. It will also look sharp with your big windows (which are already painted white). More importantly, it'll make the cute pup standout...

SW Collonade Grey would modernize the space, and look really nice with your white trim. Similar to BM Revere Pewter, but doesn't pull the same "green" undertone that Revere Pewter sometimes has

Consider SW Westhighland White. If you can, I would also carry that color up to the ceiling and make it continuous. Second, I would change the chandelier over your table to one that is rectangular and gives off more white light. Those creamy glass shades on your current fixture will make everything go yellow on you. It looks like you have warm colors in your kitchen too so I wouldn't go pure white, just this bit of off white. Try some sample boards to ensure that the color looks right at all times of day. Whatever paint you select, ask the folks at the paint store if it has any gold or yellow tint in the formula. If it does, it will go yellowish in your room, so avoid those colors. Are the table and chairs black or expresso brown color? You will have to test in your space with your light conditions to get the right color. Do you know the color of your trim? Might also be worth getting a sample of that. Using that same color but in a "flat" finish could work really well too. If you want to tone down the natural light, then you could also go to a soft sage green. So you have loads of good options. Just test out several and see which direction you prefer.

If you want to go darker to counter the large amount of natural light, you could also try BM HC-78 Litchfield Gray which is a warm beige with gray undertones but would create a lovely combination with your cabinets and table and chairs.

More color? BM HC - 108 Sandy Hook Gray. Deeper shade of brown gray.

I would just do 4-5 totally different ones and then see which direction calls to you!
