I wouldn't do 3/4 high beadboard in that area for the reasons les mentioned and also because it appears you have 8'h ceilings. It's just not going to look right. If you want the beadboard, make it about 36-42"H and paint it the same color as the trim. Having the trim and BB the same color will help hide the curve in the wall. I can see the problem area you're talking about and it looks like the drywall person built the corners out too far. I'd price out the BB and then have a drywall person give you an estimate to correct the drywall problem. I really don't think it's worth going to the expense of BB to try and hide the curve. Easier solution is to paint the wall a lighter color (with a quality washable paint) and add a runner to take your eye off the wall! Having the wall a darker color than the trim highlights the curve. Keep in mind that in shimming out the BB you'll need to remove the baseboard and shim it also, which could lead to your buying and installing new baseboard in a few areas.

Cutiepie, it could just be my monitor, but while the Frosted Silver looks blue to me, the Moonlight White looks like a very pale yellow, and the Gentle Rain looks like it's veering toward pink. Giving feedback on colors over the internet is a dicey thing, and you're the one seeing the colors as they really look in your house. When I put (virtual) swatches of Frosted Silver up against Gentle Rain, they look very different (but they are both so greyed out that when I look at them separately, I don't see the difference). If you have (or can grab at Home Depot) swatches of the two colors, I think you'll see what I mean. I think a dark color can work even without much natural light as long as you have adequate electric lighting, or light coming from the adjacent rooms. Especially with lots of white trim/doors. My dining room gets very little natural light (lots of windows but the curtains are usually closed because of proximity to the neighbor's house). Because I had lots of white wainscoting, I went with chocolate brown walls, which I love. It's cozy and intimate, not dark and gloomy.

I am a HUGE fan of Timberlane shutters in PA. The quality of these shutters is extraordinary. I have had them on my house now for 16 years - had them painted by my local painter, still look great. My DD got them about 3 years ago and they now offered the color she wanted in a factory paint job. The rep told me that these same shutters had been on the outside of their building in PA (harsh winters there!) now for 19 years and still looked great. One of the things they offer is copper guards that slip right on top of the shutter. Shutters tend to rot from water getting into the seams where the shutter dowels are held. This prevents that from happening. I think this is part of their success. Yes, they are expensive, but they will last for many decades with little if any maintenance required.

This was helpful, thanks all. I was expecting to be led to lighter ”colors” which no one did. I like some of the dark ideas but they might compete with other darker accents. In the end I think I need less color, not more, and I will sample ideas as in the first set of swatches. Thanks again for your time!
