My ALL TIME favourite B. Moore red is Bonaparte cc-64, which is actually just below the one that was recommended to you. It looks terrific paired with golds such as concord ivory hc-12, when using the red as a focal wall and the other walls in the gold, for example in a living, dining area. I think that this red would be nice with Revere Pewter for a boys room. Let us know what you go with.

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've heard that Chantilly Lace and Decorator's White take on a gray tone, but Simply White and White Dove (not to be confused with Dove White) are best paired with Revere Pewter. I just painted my ceiling Simply White, it's a little brighter than I wanted, so I may end up doing my trim in White Dove.
