Could you post a pic of the wall/room (from farther back), to get an overall feel? Gray might be tricky with the carpet color.....it also might be difficult finding a gray that works next to the tan (if you are only painting that one wall). The ones you have look too blue/purple. Maybe a darker greige would work.

I like the current wall colour, but if I had to choose, I would go with the middle one, as it is warm, hence goes better with yellow.

One more picture, from farther back, as requested.

Hi, Steve--

Totally agree with carriebear28 and akawnik that the middle tone ties best to your great current stonework and is saturated enough to pop against your whit moldings.

One thing to consider would also be the possibility of updating the sconce style to something more in keeping with a darker wall tone. Oil-rubbed bronze lanterns, maybe.

Thanks for the comments so far. The darker tone is SW griffin (SW7026) - I had assumed it was too purple-ish.

I like the middle one.....it is a warmer, almost brownish gray. Or maybe I should say grayish brown.

I would check out SW Elephant Ear; it is another gray with warmer tones to it. But lighter than griffin. Your top and bottom samples are too blue.....I would stick with warmer grays and greiges.

Another option to consider is to paint that wall a lighter color. I do like the color on your wall now, but it does kind of blend all together with the stone.

Steve, I would paint the wall the same light color of mantel. Is it white?

No accent wall. You are way overthinking this. Any of those paints are going to make your room too dark.

If you want to paint something the middle color then the paint the TV cabinet. The white really jumps out.

Add art over the mantel instead of mirror that reflects your ceiling fan : (

I think you're looking at the fireplace area and thinking what can I do to give this some interest and spark. But the answer isn't an accent wall it's art instead of a mirror that looks like a rectangle of white.

Yes, the mantel is a white/cream color as well as the baseboard and TV stand.

I agree with most of the posters, in that these paint choice are way too dark and not the right tone to compliment your tan fireplace. If you hate the current tan wall paint that actually goes well with the FP, then I would choose a light griege that works well with Tan. Try Lambs Ear by Valspar (Ace). Wallpaper is an option, but not my favorite to go alongside the FP.

The mirror needs to go, and art put in its place, like others mentioned. I would also paint the tv console the same cream color as the mantel. The white seems a bit stark and out of place, unless you go really light on the walls. The current sconces are okay. I would update, once you get everything else is taken care of. That's an easy DIY change.

These are close to your swatches. Is this what you are after? If you are only painting a accent wall, then you need to keep in mind the paint color next to it as well. You might benefit from a designer visiting your home. Some charge by the hour or 2, which is very reasonable and saves you time and money at the end.
