It is a very nice space. I agree with toolbabe about the multitude of colors going on in the kitchen. Its hard to tell what color the countertop and backsplash is, but it appears to be grey-ish. From here it doesn't look to be the greatest choice with the cabinets, but short of re-doing either, I would do all the walls in both spaces a warm grey to tie everything together. Stonington Grey, Bunny Grey, Big Bend Beige popped as potentials. Surely many others. It will work nicely with the blacks and the SS and provide cohesiveness. You could bring in something more colorful in the window treatments or maybe an accent wall in the living room. Maybe something in the orange/rust/coppery family - Copper Mountain is one. That would also connect with your cabinets.

I don’t quite know why Houzz sent me a link to this older thread but my update is this: Joan from For The Love of a House Blog knows what she’s doing. Her Ashwood was lovely in my master bedroom. Then, when we bought a new build house in 2013 I decided to try Titanium, also Ben Moore, also from her house. It read soft but tiny hint of green in my well-lit western exposure master bedroom. We paid an up charge to the builder to have a nice light taupe painted throughout the new house so my husband thought I was certifiable to be on a ladder repainting the Titanium over the new walls on the first day we had keys. Of course he was busy taking up all the carpet so he could lay wood floor the same day. The Titanium was wonderful. This past year we moved to the Deep South and I used her Gray Owl throughput the entire house we are in now. It’s my favorite and does read just a bit blue in some lights. (There May Be BM Stonington Gray in the kitchen and both baths. Just sayin’) And totally agree with 6009kitty on sample pots. Never paint without a sample on your wall. And I don’t mean a 12” square either. Light makes a lot of difference. Greenery out the window can change things too. Test it. Red

That changes my suggestion, yes…. Thinking you have a lot of the same (I have Revere Pewter on my walls and ! I have your floor tile in a bathroom). What I have found to be the perfect accent color to all the taupes and whites is black…I bought two new spool chairs in black…I added two end tables in an Annie Chalk black paint on either side of my white English arm sofa, with white lamps, and have a wall collage of antique botanical ferns that I reframed in black. But, not any black…B.M Midnight 2131-40. That is what I would paint the vanity. As for hardware, in a bathroom, I like chrome finish…bright and clean, but that is your choice. Otherwise, brushed stainless is my choice. One word of warning, sometimes brushed nickel can look pink, or sometimes a grungy yellow tone. Not my favorite.

Sorry, I don't have a photo right now, but I'm not sure that would even help you. You really just have to test it in your space with your lighting. I recommended it recently to a friend who said it ended up reading pink-ish for her. We didn't have that issue at all. WB worked so well but each space is different. You just have to test it in the room. Paint it on a large piece of foam core board and move it around the room throughout the day.
