You can't divide things up. If you want one large room you will not have a kitchen and living room anymore but a kitchen with living space. This is a bad design and a good way to keep homeowner spending money to remodel Once everyone does it the trend will be to bring back separate rooms. Here is some info about the open floor plan. 11 Reasons Against an Open Floor Plan

Look at BM Carrington Beige, BM Clay Beige, BM Edgecomb Gray

Here is the problem - you are looking for a paint color based on 2 inch square swatches compared to huge expanses of the colors already in your home. If you have a sample of the countertop that you can take outside - that it the ideal answer. If not you will need to make do with a gerry rigged method using the counter top in place. Get a large white sheet. Gather samples of the colors that must stay ( a drawer front, a sample of flooring that closely matches if an actual sample isn't available, a sample of the granite. Gather as many colors as you can from the neutral and heavily muted colors at the paint store. The lighting in the paint store will confuse your brain - pick up everything even if it doesn't seem good in the store - you may be suprised by what works when you get them home. If possible, take all the colors outside and cover a table with the white sheet. Lay the samples of the colors that must stay on the sheet and place one color sample at a time next to the colors that have to stay. If it works in natural daylight it will work anywhere. If it is not possible to take a sample outside cut a hole in the sheet and let a small section of the counter show through the hole in an area near a window. If that is not possible get a good lamp with a 5000k lightbulb and place the lamp so it shines on the hole in your sheet. You can limit the amount of any sample of the things that must stay by doing cutouts on the sheet. Typically one or two colors will feel right. This is going to be the hue you want. More than likely when you purchase a sample and paint a large section of wall it will read more vivid than the color you picked from a tiny sample. More space- more color. But you will know that you are in the right ball park and can use tools like EasyRGB to discover similar colors that are slighly less saturated. I worked with Miller Paint when I first discovered Devine. They were amazing. Don't know how they are today, as it has been 20 ish years ago. If I were in their service area I would work with them again in a heartbeat. Hope this helps narrow your choices :-)

I feel your pain! I got the Accessible beige sample and almost don't want to try it just go for it. Colors are so weird and can make you feel crazy! At least me:) We have divine white cabs and I feel they change from warm to cool. My husband has his office cabinets painted DW too and they look totally different from our home (actually I think better and his counters are slightly more cool). This is DW next to Nomadic Desert. Have you ever thought of hiring a color expert like Kylie? Maybe for such a large space would be good to get a 2nd set of eyes? Or just go for one and hope for the best. I know I have stressed too much about it:) And no one needs to do that.
