Chantilly Lace has more gray and Simple White has more yellow. They are close to the same light value, so the combination may make the trim color look grungy. If you want the walls to stay that light, you can use the Chantilly Lace on the walls in a matte finish, and on the trim with some sheen. I would look for a slightly deeper color for the walls so you have some contrast to your trim- toward a light sand color or even a white with a tint of blue or green. You have to try the samples in your own light to see what works. Don't forget to consider the flooring color, which will have a big impact on how the walls look.

Or you can go even darker in some rooms if you get a lot of light.

Thanks so much! I love these sample pictures. The first picture is my favourite I even have the spindle chairs. I have been looking at coastal pale floors that are in style but what I really love is the floors in the first picture.

Catherine, your question made me think of this blog featuring a lake house with quite a bit of blue and white. In this case they used Extra White from SW for much of the interior. It's a lovely home, inside and out.

Thanks so much wonderful pictures for inspiration!

Using a light beige on the walls gives you a calming neutral backdrop for your blue and green furnishings and accents.

Love the light beige walls in calidesign's photo.

This link shows the basement in the same home I posted above. Pretty sure the wall color is SW Agreeable Gray.

I agree the light beige really is nice. Thanks to both of you.

IMO beige and blue not working in my head. Why not just keep the same Chantilly everywhere it is a nice white and in a matte finsish will look different that the cabinets and trim. Make sure all your lighting is LED in 4000k too before doing anything else.

I started the thread because they are finishing the framing this week so still not to late to change the Chantilly lace colour on the cabinets etc. But based on everyone’s input keeping Chantilly seems a good choice but stick with a slightly cool white even sticking with Chantilly for the walls. The blues (like a Chinese blue & white vase) and greens I like are bold not pastels so I think this works.
