What kind of saturation are you looking at? and what is the lighting like in the room?

On the north corner but lots of windows. I do want as dark as I can go and warm and rich !!

I love dark brown and think it is so underused and underrated!

Aktillery, a commenter here, painted her living room in SW Brainstorm Bronze, and it's stunning. She has a row of doors and windows and high wood ceilings.

Check out BM Tarpley Brown also

SW Status Bronze

Really like them both. I always go with Benjamin Moore but certainly would lean towards the status bronze.

We have used BM Middlebury Brown in our master bedroom for the past 11 years (3 different homes). Love it.

Yes, Middlebury Brown is another I was going to suggest. Didn't seem quite as warm as the Tarpley

Agree. I really like Tarpley as well.

Benjamin Moore Mink!

Beautiful, dark rich brown.

I love Aktillery's brown walls and recently saw a neighbor who had painted all the walls on her first floor a dark brown that was gorgeous -- but they both have white trim. Is your wood trim the more typical dark trim? Are you sure you want brown on brown on brown? Or brown on brown on orange?

If you want layers of brown, keep in mind the reds and oranges in your wood trim and the terracotta floor. They are all going to have to compliment each other without bringing out anything you don't want to see in the others. I think you could have a challenge pulling that off.

If you're going with dark brown walls, I agree w/lascatx, definitely paint your trim and crown moulding white or cream.

If you don't want to paint the trim, look at a mid tone or lighter shade.

My dining room is dark brown--Behr Wild Horse (I was paying attention when you said you wanted to use BM, but I'm going somewhere here.)

Not as sophisticated as the browns Tribbix suggested, but I was going for "Hershey Bar" and I'm happy with it.

The thing is, I tried out a bunch of browns. I tend to use a process of elimination--at various times of day I evaluate the samples and at each point eliminate my least favorite. Usually there's a clear winner. With the dark browns I got down to about 5 and didn't really have a preference. Any of them would have been fine, and I picked Wild Horse out of the 5 more or less at random. So my point is that, for me at least, there was a lot more margin for error in choosing a dark brown than, say, a blue. An I think more margin with dark colors than with light colors (light colors seem to be more chameleons with changes in the light.

What color is your wood trim? That would seem to be the wild card in this. I have white trim, so it wasn't an issue for me. I can definitely foresee limitations for you trying to pick a brown that works with your trim.

Looks like you want a darker brown than I have but we went with a SW Hopsack on the walls and SW Pro Classic White on the wainscot and coffered ceiling. I thought it was too dark at first but was convinced(ok pursuaded) to try it and we love it!!

Thank you for all the suggestions! The trim is pine with very few knots stained Early American. Not going to go white or cream as the rustic feel of the room is what I like but may have to consider mid tone. I do my own painting and never afraid to try something and change my mind! Not after the whole room is done of course. I do have to be careful with the terra cotta floor.
