RP contrasts enough with white trim -- it's the light wood furniture and the different undertones that aren't working. Your low contrast art adds to the effect. If the furniture stays, I'd look at the RP for the hall and more color in the DR. RP would go great with eggplant if you are considering that direction. The eggplant would also look good with the teal glass in your cabinet. The new photo with the test swatch of RP also shows some Asian china pieces. This grey was one I mentioned earlier (evening dove) and it would look great with the orange/paprika color as well as the dark blue in those. You can see the pairing with peachy and orange tones in the pillows and flowers. Might be easier for DH to handle a deeper grey too. Some guys can't deal with anything resembling purple (you could tell him it's warm or fruity cocoa -- LOL). I think it would also transition well with RP in the entry (look at the ceiling -- a similar idea). Looking at RP on the BM website, they show it with mink and dalton blue-- that goes to a darker grey brown (almost a slightly greyed cocoa) and a pale grey blue (that could go on the ceiling if you get adventurous). Your crystal chandelier (see it in the reflection) would be very pretty against any of these darker colors. Have we confused you more? Will the RP work in the entry so the painter can keep painting? LOL

I have revere pewter in my kitchen and in my bedroom (trim in both rooms is also Mascarpone) and those two rooms couldn't be any farther from formal. And I do think it works really well with Edgecomb Gray. I can't seem to get into Photobucket right now, but you can see a couple pics of the kitchen at the link below. (Note that the cabinets are not Mascarpone but (most of) the trim and the ceilings are). Here is a link that might be useful: Revere Pewter/mascarpone kitchen

I see brown/green undertones in Revere Pewter; I see gray/brown undertones in Light Pewter Revere Pewter is a beautiful wall color. However, like any paint color, it will be affected by natural light. I have it in my living room/dining, which get east, north and south light and it Is perfect thought the day. You have very little natural light in the basement room, so going light isn’t always the answer. If you have a dark room where you need to have lights on all the time, do something deeper which works with the lighting you have. My experience is darker makes a space look bigger because the corner shadows aren’t as obvious.

A mini buffet of possibilities. No way to know if the Lowe's version of the colors is accurate without measuring them - could be spot on, might be miles off. Existing wall color is strong. It's going to influence how you're seeing new swatches If it's just one coat, it's not enough. Need two coats for proper film thickness thus color rendering. Yes, it could be the light and other stuff too. Colors influence each other. The color relationship of anything "orange" in nearby context of lower chroma, near neutral colors, like Revere Pewter and Colonnade Gray, from this hue family can make them look blue/purple/purple-blue. Home brand BenM and SW versions of Revere Pewter and Colonnade Gray are nearly identical. Biggest difference is Chroma: Colonnade is slightly less colorful, more gray than Revere Pewter - most people would probably not even notice a difference.
