I like how the wood cabinets break up all the painted walls, so I wouldn't paint, but I can see how it would be a more cohesive look to have them the same as the doors and trim out in your home.

You've selected 1) Vapor Trails 2) misty meadows..... i added 5 to the way left. Nimbus gray, first snow, silver mist, solitude, baby breath........ Quiet moments is the one just to the left of the first one you chose. I don't think it shows up here well..... Thoughts as to if you would change or would still be inclined to go with one of the first 2....?

I like a lot of light as well. I think everything is well lit except for your family room. Definitely not enough light in there (especially if you want the option of a brightly lit space. There is no center lighting and everything has been arrange around the edges of the room. IMO, what you have is a HUGE span with zero lighting which is not at all adequate. Some people prefer room edge lighting and that’s what they’ll recommend. But if you like a lot of light, I don’t think the way your designer set things up will satisfy that need. If it was my home, even though the ceilings are only 8 feet, I would want a center fixture (small chandelier or semi flush)...something pretty. If you are not sure about your furniture placement they can always install the box with lots of extra wire looped in the ceiling so you can adjust it later. Just take pics of your ceiling joists when it’s all opened up (if it is opened up) so you know where everything is located. Makes it easier later. You’ll have a little sheetrock repair, but completely manageable. I would add more cans/wafers around the center of the room and put them on a dimmer. You can always turn them off or dim them if it’s too much light, but if there’s nothing there, you’re stuck with a dark room and no real way to fix it (other than having your electrician return and hack up your ceiling). I’m not a fan of LED, but some people love it. Just make sure you like the type of light they put out before you bite the bullet on them.

You could start with a professional colorist or start at a BM or SW store; I have met some paint folks who were genius with color. Our local Lowe's had a guy; really miss him. You can work with a color wheel, but I think that will confuse you by providing too much info. If you look through a paint store's color cards that feature colors you like and varying shades of them on the same card, you can take them home where the LED lighting will give you a better feel for how each works in situ. I suggest you each go to the store separately and select your paint color cards. Sit down and discuss, justifying your choices and see if you can narrow the cards down to 2-3 for each of you. Then you can order larger samples from www.samplize.com so you can see them on different walls in each room, in different lighting and weather conditions (sunrise, sunset, nighttime, mid-day, raining, sunny, gray) to nail down how they will work in your room, with your lighting. You can also acquire info on other colors, not on the cards, that are designed to work with them in a complimentary way. Now, part of selecting color (really the last step in most decor projects) is to consider your fabrics/textiles, which can't be changed as easily as paint can be. If you have your rugs, upholstery, art already it will be easier to do. If starting from scratch, you'll need to start mood boards for the furniture you plan to purchase. Do you have samples of the flooring you've chosen? That's part of your "board" too. It will be easier to make decisions on the individual rooms if the flooring is already installed. Placing the color cards with the board will help focus in on the best color for your place, and it may not be the one you have in mind right now. Be sure to take a cushion or matching pillow from the navy sofa with you as you shop for color and other fabrics/textiles. Big job but worth taking your time!
