A: Thank you for your question and we would love to provide you with some suggestions!
Firstly, I would add an area rug that has an accent color. I would select an accent color that would also be included in a piece of art on the fireplace tile or other adjacent wall, table runner, accessories on the table.
You could also introduce a different finish in the room (dining pendant, accessories on table top, artwork frame). This could additionally add some warmth to the space.
Lastly if you introduce a warm accent color that is included in art, area rug, accessories, you can keep the walls neutral or lighter. Here are some great neutral wall colors: Neutral ground, Amazing Gray, Agreeable Gray by Sherwin Williams, Light Pewter, Revere Pewter, White Dove, Chantilly Lace, Decorators White by Benjamin Moore
