Distance would be a beautiful color for the DR, but I may be biased. Mine is a similar color. Silver, gold, brass and crystal and wood tones, espcially darker tones, all look great against it. Hale Navy is a great color too, but I'm not seeing it in the kitchen with dark wood cabinets (paint the cabinets white and I'd love it, but the counter might need to change too). The FR could take that dark color on the walls, with the vaulted ceiling, light carpet and lots of windows. Am I understanding correctly that these are photos from the listing (looks like and MLS watermark)? And you are moving from another area so you can't go back and check colors? Can your realtor or anyone you know go back and take some photos with the color chips? Would you be willing to have the realtor and a color consultant look at that for you and work with you via photos/videos? My SW store has one or maybe two consultants and I know some folks here have used color consultants via phone and nternet. Maybe they can weigh in on how that could work for you. My biggest concern is the kitchen, and I'm not sure if by painting the trim lighter you mean the baseboards (don't), the trim around the entry door (do), the mantel or something else (like painting the cabinets white?). The issue in the kitchen is the dark wood with a lot of red in it. There also appears to be some warm tones (pinkish beige) in the countertops. If you are going to paint the cabinets white and change the counter, I think you can use those cooler greys in there, but I think you might need a warmer grey in there if all you plan to change is the wall color. If you go with a cooler grey or a blue next to the stained wood, they will accentuate each other -- you will see more of the warm tones in the wood and counters and more blue in your grey. There appears to be some of that going on with the current wall color and the green/grey. You could have similar issues with the brick and mantel in the FR. Collonade is one of the colors I tried in my home and it definitely has more green in it. It has more grey than what is on the walls now, but may not give the look you seem to be after. Can you try Agreeable Gray or Accesible Beige -- possibly Alpaca (all SW) in the kitchen? Requisite Gray looks like another possibility but darker. Mega Greige is warmer (slightly more toward beige) and darker still. I would probably chose one of the lighter shades for the entry and then go a shade darker in the LR, but not too dark so it contrasts with Distance in the DR. The FR could go lighter or darker, but it isn't clear where you can transition between the kitchen/breakfast area (looks like that needs to be the same color) and the FR.

Its not the OP who will see legal issues...its the modular company who had their architect sign off on the plans that will get sued in the end. Even in Yankee Barn attempts to go after the OP, the OP can turn around and go after the modular company. Since it sounded like OP was already planning to change the plans and was in the early stages I doubt Yankee Barn would go after OP. At this point either the plans were changed heavily or OP could hire a contractor to finish off the inside of the house and avoid showing the town building department as much as possible. I doubt Yankee Barns legal team would waste funds to take someone to court over an online discussion board. If OP had to pay for plans in the first place...its highly likely that the modular company contacted Yankee Barns architect and bought them. Its 2018 and with websites like this i doubt a modular company would risk it.

Congratulations on your new home - how exciting! I would not paint the walls grey/blue/green due to the orange/yellow wood. Those colors would look nice in your home but may feel a little old-fashioned to you. In my opinion, grey has been overdone and it's time for something fresher. I would paint both the walls and the wood trim the same soft white to give it a more modern feel. The trim is not very substantial so just paint it out altogether. Bring in color with your furniture or art. When you eventually replace the flooring you can think about changing the trim too. Look at Benjamin Moore OC-117 Simply White, or perhaps OC-118 Snowfall White or OC-149 Decorator's White.

IMO blue/ grays are hard to work with if i have a client that has to paint before a house is completed i highly reccomend a pale grayed green it is much more neutral than gray and seems to work with everything. Sea Salt from Sherwin Williams is a good color it is not the same as BM sea salt.
