I would stay within a shade for the cement gray, do the spaces share a common wall? can you take a photo from the arm chair angle and the couch angle. well just more photos lol. what you really need is an accent color in the room. its all too brown.

Does this pic help?? I desperalty need help w colors for my home.

Also part of my little living room

Not clear how the cement gray works with this - flair is asking for a photo of the next space so we can see / tie them together

Hi, I have a sampling of how cement gray looks with some other BM grays. The Smoke sample looks dark, but in Houzz photos painted this colour it doesn't look as dark.

the colour on the wall in the ref pic would look nice with yr furniture

You have a lovely home but too much brown furniture. The walls aren't a bad color but I feel that maybe a hardwood floor to replace the grey rug would really lighten up the rooms, especially with a nice accent rug to give the room a pop of color.

i like the storm color.....

What colors are in your multi colored chair or on your toss pillows?

BM shaker beige as seen in the ref pic would look nice with yr furniture and carpet and would complement BM cement grey

colours side by side

Try the pale blue from the pillows or from the sky blue in the painting behind the couch. The room could use a lot more color. Try adding solid blue pillows, too. And more lighting, consider picture lights, too. Remove plant from the corner; not much can grow in a dark corner.
