to lighten but keep with the warm tone of your kitchen, I'd sample BM Dove Wing.

What color white is the paint you have now in the living room?

although your image includes Christmas decor, Have you tried the two chairs facing the windows/tree instead of a clear shot through the room? a cozier conversation arrangement.

No more blue in the north facing room. Working from Edgecomb Gray, north light, you have the color I am suggesting to you in the art.

Purple in north light is so delicious. And this one, is a relative of Edgecomb Gray.

I would just use Edgecomb Gray again for continuity. Or look at Soft Chamois. It's lighter, but complementary.

Not a Pro here, but I like Lyn’ suggestion. I realize that paint colors look different in different environments, orientations, etc., but Edgecomb Gray turned violet in my home, but maybe that works for you. it wasn’t the look we were going for.

Go to BM web site for Edgecomb Gray and check coordinating colors...

Are you sure you want White Dove? It's very dingy. I used it on my walls (south west) and it was horrible. I ended up painting over them w/Simply White. Trim too.

You can use just about the same coordinating colors as you would white dove. It's just that Simply White doesn't come off as dingy.

Here's what she says about Simply White:

THE BEST ROOMS FOR SIMPLY WHITE

• If you’re looking for
• and have northern light, it can be a fabulous choice, offering some balance to cool northern exposure.
• Simply White can add energy to flat east-facing afternoon light or west-facing morning light.
• Simply White does its best work when it’s the only white paint color in the room (whether you have it on one surface or 3+).
• It can be pretty with some light shades of blues or green paint colors, and even some purples. Make sure these aren’t TRUE colors and have a bit (or more) of gray in them. Whereas a color like White Dove offers a slightly softer white contrast, Simply White has a bit more energy.

BM White Dove is definitely not dingy in my FL house. Some times of day, on certain walls, I think it looks a little too lemony-sunshine! My trim is BM Chantilly Lace.

OP will need to test in her own space!

she said the room was northern exposure and doesn't get a ton of light. dingy. lol

Well, most of her kitchen is White Dove (cabinets), so she should have a good idea how it will look in her space!

I feel like the art is so clean compared to the rest of the room so I would probably look for an area carpet first that adds more blues and greens then use either Edgecombe gray or a soft green on the walls.
