No idea. I presumed you tried wedgewood gray?

The pic looks very gray on my computer...like BM pewter 2121-30

It reminds me of BM Coventry Gray.

Thanks all! I did try wedgewood gray but my DH was not a fan. I think I might go with Coventry Gray. So many decisions!!!

On my monitor, I see a much more true gray than the blue Wedgewood Gray. Coventry Gray is a good true gray.

Couple of other thoughts.

By trying colors, are you buying test pots and painting them on a large swath of wall or poster board in your room's light?

A good BM store could help you find a similar gray if you can show them the pic.

Another thought. I used BM Thunder AF685 in my living room. Although the chip itself looks like a gray shaded with brown, it looks very gray (and similar to your inspiration pic) up on the walls in my northern light.

It's really about how a color looks in your light. Good luck!

Looks like downpipe or plummet in Farrow and Ball. The white looks like wimborne white

It is so hard to tell colors on the computer that I can't really say which gray it is.
As Breezy says, it may be Coventry Gray.
You might also try BM Stonington Gray for a pretty
(but not too pastel) gray with a hint of blue in it.

Farrow and Ball's Lamp Room Gray would look beautiful
in a kitchen as traditional and stately as your inspiration kitchen.

BM Silver Fox was my immediate guess.

Having just looked through the BM Color Story deck, there are a lot of greys in there that it could be:
Rainstorm
Barnwood
Wall Street
