I'm actually going to use two of the colors that aren't working for you in my new construction. Shaker Beige in hallways and foyer. And Monroe Bisque in rooms that have our medium colored Maple cabinetry--it definitely has a warm tone to it. I looked at lots & lots of taupe colors. How about Wheeling Neutral HC92? I really liked this one and it seems not too yellow, gold, green, pink. etc. and neither cool or warm. I also liked Manchester Tan but it seems more of a light cool neutral with some gray added. Since you have lots of natural light, this one may be a winner.

My kitchen is BM Pashmina. I prefer warmer tones versus gray. It can be a lot of color but it looks like you have good light so worth a sample! Good luck!

I like the chairs. What I don't think quite works is how you have spaced the furniture, all just too far away from each other. Would you consider trying a new arrangement and positioning the sofa in front of the window with sofa table/lamps behind it. Add soft window treatments to frame the window. Can you return the ottomans for ones with color? Try the bench at the foot of your bed.

It's a really lovely space but you've got very little variation between the counter, the cabinets and the backsplash, as well as a warmer color, which isn't helping your goals. I think that if you are willing to do a color rather than a neutral, then painting the bits of wall you can see in the kitchen in a blue (probably with green undertones) would help. You could also change out the hardware for something chunkier in a cool metal, as well as changing the outlet covers/wallplatess similarly. Painting or staining cabinets is a lot of work so it depends on how much effort/money you want to throw at this. If you were going to change the cabinet color I think for your goals, painting them white, or painting the bottom ones dark blue (and either leaving the top ones, or painting them white) would be helpful. Stain is a bit easier than paint but most stain colors lean warm rather than cool. You could do an espresso stain, which would break up the beige and be somewhat cool-leaning. Given the level of natural light you might find that the kitchen then ends up being quite dark. Some people like this and others don't. If you do paint or stain the cabinets, I would change out the hardware.
