Ah, yes, but WHICH white? They are not all created equal!

As a slightly more functional suggestion, what would you both think of Hamilton Blue? Also a Benjamin Moore color, and also from their historical collection. It might work well since Stonington Grey has a bit of a blue undertone. But it's a fairly masculine color without disrupting the rest of our color scheme too much.

I would keep the inside of the coffers white. The cases, maybe blue?

Though before I committed, I would get a sample and paint a foam board to move around. Make sure that color looks good in our space. Do one for the grey, as well, and make sure they work well together.

I like C2's Tempest, but I don't see anything in BM that's quite the same. Maybe BM Caldwell Green?

What is the dark color your husband would like? Has he given you any names? The room has so many windows and is large. I think it can handle a darker color. Have you purchased furniture for this room? Any rugs?

Do the blue. Most men love blue.

By dark, maybe he wants something with a little more masculine appeal? All of these would be that, but still beautiful...and not necessarily dark!

BM Ashley Gray HC 87. It's a beautiful medium neutral that should pair nicely with Stonington, which has a lot of blue in it.

For more color, like green, look at BM Creekside Green 2141-40

BM Silver Fox 2108-50 is soft and neutral, lighter than Ashley.

BM Thunder AF-65 another soft neutral if Silver Fox is something you like but the tone off in your lighting

BM Chelsea Gray would be stunning against all that white trim and a gorgeous backdrop for artwork...but it's dark.

I realize these aren't blue, but I feel like Stonington has enough blue beneath as far as grays go, that you need to either do a dark navy or forego a lighter blue (but that is only my own personal preference/opinion)

Sherwin-Williams Samovar Silver. Can't really see what it looks like online - you need to get a chip. Would work with a lot of other colors.

For the back of the book cases, you could do something fun. Like paint it orange. Upholster inserts in a pretty patterned fabric. Large-scale print floral wallpaper (removable). All kinds of clever things you can do with the back wall of a book case.

Stonington Gray isn't inherently "blue". If it looks bluish, it's because of the light. Stongington Gray can look "just gray" or even greenish.

Which is why all the color suggestions for a navy, blue-green, green-blue are good. Ideally, you should wait until Stonington goes up before choosing a color for this room. But you can't always do that with new construction.

What fabrics and textiles will go in this room? Those need to be the main consideration in selecting wall color.

i can attest to BM Chelsea Gray., although on the dark side, it is a FAB color!!! with all those windows, that room can definitely handle a color on the dark side.

as stated above, it is a "gorgeous backdrop for art"

we painted our DD's room Chelsea Gray, she sinced moved and wanted to use it in her bedroom.

i am now going to use it in the main bathroom. can't see enough about that color!!!

keep ceiling all one color! we used BM lacey pearl for the ceiling with the chelsea gray walls....

If all the rooms open to each other, too many diffeent colors can be distracting. If you have beautiful details in the molding and architecture let tththethem be the star.

Have you thought about hiring a color consultant? They can help give you a cohesive plan the entire home Doing a design board can be really helpful to see how all your colors, finishes, fabric work together.

is that similar to a designer? I have not thought about it because i know that a designer is sadly out of my price range ;(

Love that Hamilton Blue. Remember you have a lot white and windows in that room. How about Old Blue Jeans, which is slightly lighter? Or Oxford Gray (2128-40)?

Here is another rich blue - November Skies. Love the ceiling treatment.

You should definitely consider keeping the color very light in order to make the room feel spacious and open. Preferably you would want to keep it white or light shades to accomplish this.

You don't have to stick with blues and there's not a rule, but you want to pick colors that transition well from room to room (that doesn't mean match, but complement)

Because Stonington is a a gray, you could go in a lot of different directions, but you don't have to be limited to fully painted walls....you could consider wallpaper (a commitment but a beautiful staement) or wainscot, etc

You can do a wall color to make the statement, or you could go with a white that lets the furniture be the color

Some examples.....

How do you like it? It is fairly dark. Did you paint the back of the shelves?

I like it!

i love it! This photo was taken as it was getting dark out, with all the natural light during the day it looks stunning. i did not paint the back of the shelves. still deciding what to do with that area. We did also paint one of the squares to see how it would look. Torn on how to move forward.

The color is beautiful, looks stunning against all your trim and ceiling detail. Just my opinion but I much prefer your ceiling white (like above photo in original question)

I would leave all bookshelves white...I thought that from the first pic you posted in your question since they are a beautiful component of your room. The glossier finish white of your bookshelves/ base trim/ceiling trim show off their own detail as well as show off - and frame - your wall paint color and beautiful coffered ceiling .

I would leave the ceiling white. It's classic and you'll never tire of it!

In regard to your earlier qx about color consultants. TheThese are professionals who specialize in helping choose the right colors for your hard finishes such as flooring counters tile as well as Furnishings. The cost is surprisingly reasonable ranging from $250 for 1-2 rooms to $800 for an entire house. Since statistics show that almost 50% of paint purchases are made after a color mistake, it can save you a world of headaches! TThTheThey can help you recognize why certain colors don't work in your space and why. You can do a search in Houzz to locate a pro in your area. Many designers include it as a service.

Revere Pewter is a safe choice, each room can always have its own color.

Keep arches the foyer color - the oxford blue in the arches, wall, and ceiling makes the room look like there's entirely too much going on

Revere Pewter and Stonington look nice together. on your swatches...and people have used RP for a long time as a color that works nicely with many colors.....but on your actual walls in your actual house, you need to see that for yourself. Get a sample and paint a posterboard , and then move it around, step back, look at it at different times of day.

I have it here in my house, in a small office (former DR) in the SE corner of the house with 8 ft ceilings and only one window on the back (E) wall.

It looks very different on the entire-first-floor walls of my cottage we built 7 years ago that has 9 ft ceilings and is completely open/completely surrounded by windows/natural light.

It will have its own look in your space, but like I said before it looks like a safe color that would work with Stonington and is an easy color to furnish...but your floors may or may not like it so do that sample.

I would make a very large sample. RP looks greenish to some people in certain light.

Just another thought in looking at the strong/heavy look of your den with those painted ceilings .... your DR across the foyer could handle a stronger color that would balance the foyer/den/dining area if you wanted to consider something like:

I also think a substantial light fixture/chandelier like the photo above would help the painted ceiling in den feel less weighty. Just my two cents....

Either way, buy some posterboards ;)

Library/office is a great color! Subtle color in dining room is fine too if you want to go that route! The grays are only one more suggestion taking your request to 'complement' the other 2 shades/2rooms. Houzz is a great resource...I look to it often when I am indecisive about things.....but this is yours/your husband's house - a beautiful one too - so you should always ultimately do what pleases you/feels right to both of you :)
