I'm afraid I must disagree with the suggestion that green on the walls will tone down the brick. Actually, the opposite is true...colors that are opposites on the color wheel will bring up the color in both...so green makes orange look twice as orange, and yellow makes purple much stronger. We dealt with the same issue by painting our walls a soft neutral, and then putting a four to one mixture of water and paint in a bucket, washing it onto the brick chimney wall with a big paintbrush, and patting it down with a handful of cotton rag. This method works wonderfully to control the look, and keeps the variety among the different bricks, while tying it all into the room in a much more sophisticated way. It took one morning to do the whole thing, and gave the effect more of stone than brick. I wanted the hearth to relate to the dark floor rather than to the wall, because it keeps the brick wall from intruding visually into the room area...so I painted the inside of the firebox and the whole brick hearth flat black. Then I brushed a second coat of semi-gloss black just over the surfaces of the hearth bricks themselves, which made the whole thing settle into the floor. The grout stayed flat and shadowy, the nooks and crannies likewise, and the effect was much more natural than the dustiness of just flat black, or the fakey plasticky-ness of all semigloss. You could do the same thing with a deep tone of your carpet color. I wish I had a photo to show you. It looked wonderful, if I do say so myself!

Green will enhance the color of the cherry not tone it down. Neutral that goes with the other elements in the room works best. It looks on my screen like your walls have slight green hue? Try a more true neutral but one that goes with the other elements in your room. If you do go gray it needs to be a warm greige.

I can try when I get home, but the lighting isn't finished and the one window in there is still blocked off, so I'm not sure the lighting is good enough to show what I'm talking about. My gut feeling is overall it'll be less noticeable when everything is installed like when we've finished other areas, but just don't want to bring out the pink undertone if I can help it. Lisa

Again, there are so many blues and grays out there that will work with all of your colors. I suggest that you go to your favorite paint website (I love Behr and I go there all the time to choose colors for my house) and play with paint colors that you can visually paint in a room (you can choose the room). Once you find something you like, even if it's a couple of colors, I suggest buying paint samples. Once you get the samples, paint a decent sized section on a wall or two and see how it looks during the day and night. Give yourself a couple of days to decide if that is the shade you want. It's what I did when I moved in our house 3 years ago. It's how I found the shade of blue in my dining room and the shade of gray in my living room, which is in the below photo:This is Classic Silver from Behr and it is a true gray. It looks good with everything in my living room, including the wall hanging that is right of my Mom's painting. The wall hanging has a deep green border.
