I know exactly how you feel. I love this kitchen But I bought a mid century modern and the rest of the house is in these colors That room would stick out like a sore thumb and would not create a feeling of harmony. I am guessing that you picked Swiss Coffee trim because it works with your color scheme and that you wanted a softer look. If you look at m paint choices, I do have more color than most people, but when you look at a fan deck those teal blue greens that you are seeing are BM Quiet Moments, Beach Glass and Stoneybrook. I actually traded Beach Glass out for SW Silver Strand. Beach Glass had a powdery blue tone in mid afternoon sun so I needed something with just a touch more color/less gray (Chroma). I also tested Quietude, but it was just a hair too brilliant to go with the rest of my home. Colors always look more colorful on 400 square feet of wall then they do on a 1" square fan deck swatch or even a 1' painted sample. If I were you, before making any more decisions, decide on a whole home color palette. Take samples of everything you have already picked (flooring, cabinets, counters), things that you are bringing with you that you love and are not willing to part with and pick colors that work with those things. Looking at colors in natural daylight is the best way to see any hidden undertones and will get you close to where you want to be. You can tweak as you go along, but you know what the look and feel will be for the entire home. I always pick my "Colors" first, then a neutral that works with my colors, then a white that works with my neutral and colors for doors and trim. I generally paint the main part of my home with the neutral and do bedrooms, bathrooms, laundry (any room with a door) with my colors. I use the neutrals in the bedrooms/bathrooms and use the colors in furnishings and accents and art in my neutral rooms. My rule of thumb is to have 60% neutral/40% color and 10% accent color. The brightest colors that I think would work well with your white and give you a softer, but similar feel would be Rainwashed, Quietude, Tradewind, Rain.

IMO a very pure white .

I wouldn't assume that the cabinet maker's Swiss Coffee will be a match to a BenM Swiss Coffee paint chip. I'd want to see a sample first. Because the color appearance depends a great deal on the product. They maybe using a Swiss Coffee chip as the target, but oftentimes it can't be matched exactly. Plus, cabinet products are higher sheen and that shifts color appearance a smidge darker. Swiss Coffee has a healthy bump of Chroma (colorfulness). So much so that I wouldn't categorize it as an off-white. It's a color. That's how I'd treat Swiss Coffee depending on what the cabinet maker's sample looked like. Reframing it that way opens up the idea of using a more neutral white on trim and doors. Like Super White or Chantilly Lace.

I want to use Ultra pure white behr time color, so I can have some contrast but want to make sure the color hue family wont be off? Not off at all. Plenty of contrast in general but most importantly in terms of Chroma. Honestly, there aren't many colors Ultra Pure White doesn't work with because of its high Value and low Chroma. In a word, nuance. When we consider a color's lightness and colorfulness at the same time, that's called nuance and I think it's what makes UPW such a pretty color of white. Every brand (I think) has a color named Swiss Coffee. IMO, BEHRs is the prettiest. It's right on the edge of being an off-white and a light near neutral. I have a post about it here. https://thelandofcolor.com/swiss-coffee-12-by-behr/
