What color would you suggest for an accent wall in a living room

Taupe

Put in some color. Coordinate with the brick. Some brick is redish, some is brownish. Take a photo of the brick on your phone and take it with you to the paint store.

Pick out a few of samples swatches of what you think best matches your brick...then pick some colors that look good with that color.

With a redish brick, you might want to use a seafoam. Or a moss green (very muddy looking green).

With a grayish brick, you will want something warmer like a light yellow (nothing near lemon yellow). Try a peachish color.

Once you have taken the sample swatches home and think you have the right color, buy the color you like and a set of paper that you paint to use as samples and tape it up against the brick...then set back and look at it for a while.

Forest green,rust, or a burgandy

Any color that coordinates with the rest of your room. If you are undecided, look in your closet and you will see a few colors that seem to stand out. Those are the colors you are most comfortable living with and you can use one of them as an accent wall.

Grays or blues always tie in colors nicely 👍 hope it turns out beautifully for you.
