Is the carpet already installed? These are all neutrals, although the carpet has much more yellow undertone than, especially, the wall color. I believe the sofa works with either one, but the carpet and wall clash a bit.

I agree with post above. I'd do a different color carpet. Look at a more grieve tone or ivory color for carpet. Carpet has too much yellow tan. You want a grey beige or ivory carpet.

The carpet and wall do not go together. I'm not a huge fan of the wall and sofa colors together, but they can work, and I think the sofa color is better with the wall color than the carpet. The carpet is much too yellow and, for me, would be better if lighter or darker than the other elements.

Doesn't work. Carpet is too gold.

No, carpet is not installed. My only concern is that the room will look too cold if I go with a gray toned carpet.

Looks like the carpet comes in 15 colors, which can be seen HERE

Sorry, although I am copying the web page address, it won't take you to that type of rug.

Summer Fog is the lightest gray tone -

Have you ordered the sofa yet? I see that the Pottery Barn sofas can be covered in many neutral fabrics. Perhaps there's another color that would work? PB sofas and fabrics

While this isn't a picture of a nicely furnished room, the colors are similar to your choices. I looks fine to me and will work even better if you pick up the caramel color of your carpet in some accents...draperies, pillows, etc.

I like it. The carpet looks very much like sisal, which is used as a neutral with all colors.

Sisal was exactly what I was looking for and was hoping it would be neutral enough for our color scheme.

I'm with fun and dee. I think it looks fine. I think if you go with a cool carpet, it will look very blah and uninviting. Add warm wood tones and greens.
