I agree with Alex's definition of an accent wall. I have one in my LR which frames my fireplace and is a focal point for the room. Another rule of thumb is that it is a single wall in a room and not multiple walls. However, the way you are describing just bumping up the intensity of the existing wall color I agree is not really an accent wall. With that in mind, my vote would be for A (but excluding the DR walls). What you have described reminds me a lot of my local Pottery Barn store and it is a very good look and does indeed add visual interest to a large and open floorplan without drawing overmuch attention to itself as would be the case with a true accent wall. You should also take into account the amount of light that your various walls are subject too--since that also has an impact on how the wall colors are perceived. In general the stronger the sunlight a room received, the more washed out a color will appear.

Hello, my home interior walls are SW Silver Strand with white trim. Living Room/Dining Room areas needs helping hands to make them attractive. Leather beige/cream furniture, burgandy wall hangings, black wrought iron and no curtains at the 4 long 120 inch living room windows. Dining room has sliding glass doors that lead onto lanai with burgandy window coverings. All floors will be covered with luxury vinyl planks in the colors you suggest to coordinate with the silver strand walls. Can you help me make these rooms pretty and attractive and at the same time say, welcome? Help me find the right curtains for the windows, the best floor colors for the floors and would love to have an accent wall color. All suggestions appreciated.....and, you cannot hurt my feelings. Thanks bunches and bunches for your helping hands. See photos. Thanks.

I always paint woodwork the same throughout the house. What color did you use? It might be fine with the edge comb gray. Absolutely no accent color on the wall. The room is broken up enough already. For accent color use something like this red…called Hot Apple Spice because you are seeing khaki undertones in the sofa. Keep that greenish tinge when you are looking for throw pillows. etsy.com

@Laurel C thanks for sharing. You and your husband sound so interesting. Average me could never even begin to imagine such a journey. We have had lots of fun with real estate over the years, but our adventures didn't stray too far from home and what we knew. Every now and again we would talk about how it would be fun to move out of comfort zone. We never moved farther away than 100 miles...Boston, and over the Cape Cod Canal. Life has not been boring, but I think both of us have a bit of wanderlust in our genes. My lovely high school nuns were from Louisville . My French teacher would greet us every morning..."Bon Jour, y'all" I am so glad you are near Costco. Try the stuffed peppers.
