My personal favorite is Soft Chamois, OC-13.

Linen White, Maritime White or maybe Navajo White?

The Dune white you mentioned, may be perfect for your needs. The winter white has a grayed out tone to it, and others mentioned here appear pretty yellow to me, except for the soft chamois, which looks like a light beige to me.

I agree with @kandrewspa. I’ve got BM Soft Chamois in our guest bedroom and it looks like it’s going to be great in the space when our house is finally finished and we get flooring & furniture in. This is a south facing room, FYI.

Thanks everyone! I tested my fan deck swatches in the room. Soft Chamois is worth trying. It does look very beige in A C's photo, but it's going much grayer in my room. Worth seeing what it does in a larger sample. The other colors are nice but either too yellow or too beige for what I'm after.

Interesting that you’d like a gray color palette because I’m actually planning to use gray décor in this room. The headboard is gray fabric and I’m using a pale yellow, blue & gray comforter with it. Here’s my very rough mood board. I think the wall color does well with the gray.

That is a beautiful mood board! I love the mix of gray with the warm woods and the gold tones of the bedspread and rug. While I personally love gray, I won't do it here. I'm thinking that the seeming shifts between khaki and gray might make Soft Chamois a great true neutral--worth seeing how it appears in a larger sample.

Also look at Sculptor Clay from Behr... BM should be able to match it. A neutral I found on here, a go-to color for some decorator I don't remember.

I have winter white in a condo. Kind of blah.
From hextoral.com ...SC darker but richer. Kind of a chameleon color.

Thanks! Looking at that comparison, Soft Chamois is more what I'm after. But I'll pick up a swatch of Scuptor's Clay. You never know what something will do in your own space.

Yes, def different, darker... has to work with your overall vision! It's pretty neutral though.
