That couch is definitely the Nordvalla Grey. I just purchased the chair with that same cover and am looking for a couch. I will purchase the slipcover from ebay and came across the same problem. The Dansbo is a very dark grey.So it is definitely the Nordvalla Grey.

I have warm creamy whites in my kitchen and white white in the bathroom (subways, tub, sink, towels) with carrara on the vanity. It's just not a thing to me. Yes, different whites, but you can't see the kitchen from the bathroom and it's never occurred to me they need to match. ETA: Although the bathroom is a more pure white, it doesn't feel cool to me, just clean. I don't really care for cool shades in any quantity.

I hear you! You don't want a color, you want a neutral on your walls that will work well with your sofa. I have a collection of large color samples, but you probably don't. What I would do in your case is go to the BM store and pick up the 2"x 3" color samples that they have free for the taking. Pick up some of everything, even colors that you may think won't work. If you feel guilty for taking so many you can always take them back when you are done with this exercise. Once you get your samples home take one of your sofa cushions outside - lay down a sheet or something over a table and set your sofa cushion on the table. You want the cushion to be in direct afternoon sun on a clear day. Get a sheet of plain white paper and set that down on your sofa cushion. Then lay 2 of your samples on the white paper. Step back and look at the color combination. Pick your favorite. Lay down another sample. Do this until you have limited the color samples to 3 to 5 samples that you think coordinate well with your sofa. Remember that you have picked out colors that work together every day for most of your life when you pick what you are going to wear or what makeup you are going to use, what bow to place on a package. The reason that I say to do this in direct afternoon sun on a clear day is that we do not have any artificial light source that works as well at rendering color as the sun. It will show you things you won't see in your home till after you have painted a large area, People may disagree with me, but every artist tries to use direct natural sunlight when they paint so that they can get the colors just right. When you take a painting into your home the colors still work together. They may look less vibrant or may look cooler or warmer because the lighting is cooler or warmer, but all the colors are changed in the same way by the lighting so they still work together. (You don't change outfits based on being outside or inside, you wear the same outfit all day and it doesn't suddenly clash when you go into your office. The opposite does sometimes happen. Great hair color until you get in the sunlight - it just turned green! Yikes!. Once you have picked your 3-5 top contenders buy samples of your top 2 or 3. I don't actually recommend poster board, I recommend using 140 lb water color paper. You can buy 30 sheets for about $10. It works very well for painting samples, doesn't warp and has a similar texture to a painted wall. Tape the edges down before painting. Paint 2 coats. let it dry, remove the tape and you will have a narrow white boarder on the edge of your sample. If you want to paint an area of your wall paint it white, then hang your samples on the wall. Then move them to another wall, move them all around the room. live with them for a few days. Look at the color in the morning, afternoon and evening. If one seems a bit too light or too dark or a bit too blue or green you can tweak your selection, but you will be close to that perfect combination. Have confidence and enjoy the process!

When there are several different natural lights coming into the room, I go with the one which delivers the most light…so, guessing the light from the slider is the dominate light (West). Try B.M. I know you really want a white for the walls, but with all the different light neutrals you have in the tile and the cabinets, give a moment’s thought to White Winged Dove, as it has a LVR of 76 (meaning not a whole lot of undertone) I think you need to consider your floor tone more.
