I'm more concerned that anything that isn't matte will show the unevenness in the wall that you talk about and make it stand out. I've had this argument with DH and the architect over the years and I've folded and gone with matte for the very reasons they state....no lap marks, reduces the impact of imperfections in the walls.... The only way I know to avoid lap marks is to paint it once and paint it well...it's when you go back over stuff to catch those areas where it's thin or didn't cover completely that you really see the sheen build up and it shows. I don't see a pic of the room.

Got a sample of Quietude and love the color on the poster board but now already know the ceiling must be white and we will hire a professional to paint the room and cut it in. Could someone please suggest the best SW white for both the trim, doors and ceiling to compliment the Quietude.

oh yes, they can't play with the paint unless they have certain amount of it..you need to make a separate sample. lots of money in our case, yes. (our GC included 3 samples per room; but we needed more..)) we have a main space (entry, living, dining, kitchen, corridor)-that's one color plus one corresponding ceiling color then a family room: another color plus ceiling color then two kids/guest baths-two different colors plus two ceiling colors, accordingly then four bedrooms-4 colors plus 4 ceiling colors then a master bath -yet another wall color plus a ceiling color it sounds like a mishmash but it's not. I put all the samples together(they were on paper), and moved them around the house..and stared at them for a day or two. to see whether they flow and work with each other they did because of the light changing throughout the day, some of them read as very close colors sometimes. Interestingly, I do remember every name of every paint. Working on them so hard. But I have it on a list too the problem with tweaking the formula-harder to match within X years if you don't remember the color, yet still like the paint. You can ask though to open an account in the store so they put your custom colors in their system. Affinity is great quality..used it in some rooms in our previous place. The one we've got now-should be cool too but they bought a lower-grade paint. I don't think it's on our GC (he's an extremely transparent guy, and he'd give us a choice) rather think it's on the painting sub. We figured it out by pure chance and it was too late by then. Let me tell you-the difference in how it holds is striking. I'm livid sometimes thinking about it. Actually my husband wanted to repaint with higher quality paints everything before moving in..but it would mean another couple of thousands probably more..and we had to move fast, and I was tired as hell.

I don't know anything about your house or the décor so it is very hard to give any kind of advice, but I am wondering why shiplap? Sometimes when I read a post like yours I think that you may be trying too hard to be different. I like a bit of a surprise, like colored ceilings or trim or both. Like using bolder colors and more color, but I generally try to keep the design elements simple and let the color be the star. Is the shiplap going to compete with the color? More isn't always better, sometimes it is just more.
