This is the hood style Hood and two pull out cabinets either side of stainless slide in range would be Silas grey Fridge and drawer microwave Thought of espresso for island but decided Silas grey as DW and apron sink both stainless. Butler pantry not visible from kitchen Will be espresso flanking wine fridge with breadboard back in espresso and a walnut counter top. Want it to feel like an extension of dining room Thinking we can always add a shallow 15" x 3' beverage/ coffee station across from island on bathroom wall in future. Highlighted walls will have some form of a bead n batten wainscoting.

I came across this article from Architectural Digest and I think it answers all your questions. Eider White with Repose Gray with Bright White for ceilings and woodwork and Dovetail for the adjoing room. Kitchen has your colors in reverse, but none the less it is truly professional help from a respected publication: https://www.architecturaldigest.com/gallery/what-not-to-do-with-monochromatic-paint-and-decor

I agree with lynartist. Agreeable and Repose are a lot alike. You don't have know what these numbers mean in order to see that they illustrate how similar the two colors are. If you use just one of those colors throughout the unique light exposure in each room is probably going to make that one color appear slightly different room to room. So, you get flow and continuity because it's the same color but its appearance will shift based on the room's inherent quality of light.

Then go darker - Dovetail is on the same color range. Or go white? But really just shooting fish in a barrel here - best to show us floor finish and exact countertop to best pick.
