On the Cambria website, they list complementary colors for Brittanicca Warm quartz. They are Benjamin Moore paints and when you click on each swatch, it will tell you the name and number of the paint chip. A visualizer is also located there. https://www.cambriausa.com/designs/design-palette/#!/designDetails/brittaniccawarm

I might consult w an interior designer. The shapes are unique . The space is large . there are likely some opportunities at the dining zone . Continuing w changes without a cohesive plan is often not the best w a space like this.

No one can tell you whether that color will work in your room. People can tell you if they like it in their house, but that doesn't really tell you anything. Get a sample from Samplize.com or paint a sample board that you can move around the room to get the effect of different types of light at different times of day. Be sure to look at the board against the other surfaces in the room at the same angle as the cabinets. For instance, don't lay the sample down on the counter to look at it. If you're doing the painting yourself, be sure to research the correct (very time consuming) way to paint cabinets as the finish will not last if it isn't done right. The door style of your cabinets is very dated. Did you look into cabinet refacing?

IMO you are doing this backwards. Wall color last choice , Counters after kitchen design and cabinets are chosen You cannot choose colors with no lighting in place You do not mention flooring which BTW needs to bechosen before any of these things are decided . I think you need a ID to help and honestly 20' high ceilings are horrible for lighting , sound control and huge $$$$ for heating and cooling for no purpose . Too late now to fix that but slow down these other things until the space is at least lit . IMO cabinet color trumps wall color for sure Lovely looking home why fake plastic stone ?
