We had the same issue, as well, when we moved into our new home 6 months ago. I felt pretty overwhelmed by it and although I got so much good advice and help here when I posted a question about it, I just could not visualize the finished product alone. I ended up hiring a Benjamin Moore color consultant to come to my home to meet with me for an hour....she ended up staying an hour and 20 min and it cost $112...money WELL spent because I really did not know about undertones and which white to use for trim (who knew there were SO many?!) and flow and where to start/stop a color in such an open space, etc We used one color for our 2 story foyer, the stairway/catwalk area which opens to the back of the house, and the 2 story great room or family room, whatever...we elected to do this because visually when you walk in to the house from the foyer, you can see the stair/catwalk and over into the family room...I am happy with how that turned out. Our kitchen/morning room is adjacent to family room too, and we painted those one color... Our dining and living rooms are in the front of the house on either side of the foyer and they are each painted their own color So we used 4 colors in the big open space but they are complimentary and they flow well from one area to the other...Truthfully, I am still a little bit on the fence about the kitchen/morning room color. Great color although I NEVER would have chosen it myself, works very very well with the finishes in the kitchen, LOVE it in the kitchen itself, but not sure about it in the morning room....maybe too dark, not sure. But its paint and I can change it down the line if I want to. The biggest thing I learned is that really there are no hard and fast rules. Yes, there are things to consider, lots of things. But if YOU like the color then go for it.

Take a look at SW Repose Gray, Mindful Gray and Dorian Gray. They are in the greige family but have a hint of green. With your honey oak cabinets and green countertops I think you would like any of them. The Repose is lightest. We have used it in two bedrooms, a hall and home office. It works great with gray carpet, wood trim and white trim. Good luck and let us know what you decide and for sure show us before and after pics!

The blue and green and brown are going...once 2 walls separating kitchen are gone it will all be open. It's gonna be a large space and new color will have to go down hallway too. Not sure what will look best with the carpet, trim and kitchen cabs. Go all one color? Go a darker hue of same color around cabinets/foyer? Do an accent wall? Keep it simple and just paint same color for everything?

Picture of the kitchen too - visible from the dining room and living room... I don’t really like any any of the colors in the kitchen right now. Definitely not my “style”. Im hoping to tackling painting the cabinets and changing out the countertops to white, maybe making the island a different color like navy or blueish grey, but trying to take baby steps and pick out new floors and wall colors first. Huge props to professional designers and their talents, because just picking out a paint color has me paralyzed ... I can’t even imagine how I’m going to pick out flooring or colors for the kitchen next Very overwhelming 🥺😩
