We recently bought a house and repainted the entire main floor with SW Pure White. it’s wonderful. And we will be painting the newly reno’d basement the same color after considering several others. I think with the warm and cool tones youve got in both living room and kitchen to stick with a neutral white.

Of your samples, I like Chantilly lace the best.

What about more of an off-white? BM Intense White, BM Paper White, SW Shoji White are all good, neutral off-whites that won't be stark or yellowy.

BM Oxford White is a good true white that is more neutral than simply white but has a bit more dimension than Chantilly lace.

When pairing two white colours together you need a minimum contrast in Chroma (colourfulness) of at least 0.2 to keep one from looking dingy or dirtied next to the other.

Neither Oxford White or Chantilly Lace provides that when teamed with Behr’s Ultra Pure White.

I would paint the walls same color as the trim, except in either eggshell or matte finish paint.

I really like Simply White. It will be a lot brighter than what you have now. I think you should only use one white. But you could paint the kitchen wall adjacent to the tiles Balboa Mist a pale gray.

It is better to sample paint on foam core boards so you can move it around and not negatively impact other samples. I use satin on trim, matte on walls and flat on the ceiling.

I love your space and furniture. You could move the sofa away from the wall a few inches and bring the other two chairs closer to form more of a conversation area,.

These whites have enough difference in Chroma with Ultra Pure White.

I also just had a whole condo painted SW Pure White, including the ceilings (which had orange/gold/brown marbling in the trays, and every room was a different color - green, pink, blue, tan, etc). We had less than an hour to look around the condo so I had no idea how things looked in the day vs the night, winter/summer, etc. My go-to paint has always been a Devoe which no one seems able to duplicate now so I took a leap of faith and picked Pure White without seeing it on a wall. I told the painters to have it done by the time we got there (from 1000 miles away). I love it; not yellow, not cold, just right; very close to my beloved Devoe.

I definitely prefer the Decorators white. One of the others is way too bright and the other too creamy. DW is bright but not stark and it seems any undertones it does have go with your space

My vote would be to use the Ultra Pure White by Behr. Get it in Flat if you can.

Thank you ALL for your comments and advice! I will get a sample of SW Pure White to compare it with the other options. Among the initial colors, I am now actually leaning towards Decorator's White for the walls - it definitely works in the kitchen and it actually may balance our (mostly) warm furniture in the living room. Using this paint in both rooms would tie the two spaces together.

For the trims, I am leaning towards Behr Ultra Pure White or BM Chantilly Lace.

Considering this is a room that gets A LOT of natural light (particularly in the morning, windows facing east and south), would there be any particular recommendation for the sheen? I was thinking eggshell for walls and satin for trims. We have a small daughter, so we value durability and ease to clean...

Please go matte for the walls. Matte is scrubbable. No problem. I made the mistake one time to use eggshell on the walls and I could see every imperfection. I use Satin for my trim.

Decorator's White is very popular. I think you'll be happy with it. Good luck!

For trim, do the same color as walls but use a different sheen. We have SW Pure White on walls, ceiling and trim, but all different sheens.

Completely agree w Juliet. Mixing the two whites will be strange...
