Thanks for the feedback - which furniture do you think the choc mousse would clash with? Any thoughts are appreciated!

This is what the painter I have recommended as a color

You have a carmel colored couch. Thats the one I would worry about the paint going with. It looks to be good leather, and they are not cheap to replace. Second would be your tan chairs, which usually go with a lot, but, you are trying to choose colors that are too close to them, and they will clash. Thats why I suggested a cream from your rug for the walls. You can choose the blue in your rug for pillows and accents. You need to tie all this together, not pull it all apart.

It's impossible to accurately judge colors from a photo, but just taking a stab here - it would appear that the Chocolate Mousse color is redder than your side chairs, which probably wouldn't look good.

Chocolate Mousse has these characteristics: 78 lightness/10.8 chroma /71.7 YR orange hue family.

Near-neutrals from the orange hue family are notorious for looking "purple" or red-purple. That's probably what would happen next to the chairs.

Also, this paint color is similar in depth of color to your seating pieces, so you'd lose contrast.

I would go for a lighter version of either your couch or your side chairs. You might look at this group of colors, also off the old Ben Moore deck: 1037 Muslin, 1038 Everlasting, and 1039 Stone House. They're gold-based, but lighter and lower chroma (more neutral) than Roxbury Caramel.

If you want a color that's more khaki like your chairs, I'd check out SW 7532 Urban Putty or 6149 Relaxed Khaki.

Finally, it depends on what colors are going on in adjacent spaces; you want a proper flow from one wall color to another. So be sure to consider that when choosing your wall color for the den.

This is super helpful! Thank you!!

just one question before i go to consider those new shades, do either of these two shades ‘fit the bill’ for either of you?

Additionally, the far left swatch is called Harmony

Hi Rebecca, I assume you mean Ben Moore AF-90 Harmony, plus AF-325 Handmade.

I looked up the color data on both of these. Handmade I would steer away from, as it's higher chroma and I'm assuming you want to get away from strong color with this change - is that correct?

The AF-90 Harmony is very similar to the 1038 Everlasting that I mentioned. Nearly identical in Lightness, and same position on the color wheel: at 83, it's on the warm side of yellow.

The difference is that Harmony is a little more chromatic, at 15.5, whereas Everlasting has just a tiny bit less color (chroma) at 14.6.

So we're either both on the right track, or the totally wrong track. ; ) But at least we're together.

Pick up the chips first and check them in your lighting, during the day. Get a sample or two of the most likely candidate(s), and test BIG patches, apart from each other. Testing on a strong lime green will mess with your perception a bit, but if you trap the color near the molding, it helps a little.

Thank you so much!! You are so helpful - I was just looking at your suggestions and I do love Everlasting and Stone House! I will check out your link on painting samples too - thank you ☺️
