Do you want a light tone or dark? Here is a chart of SW colors, I would choose the top row, second color but that's me. https://westmagnoliacharm.com/blue-gray-paint-colors/blog/

Near neutrals from the Blue Hue Family neighbourhood.

Every grey paint colour belongs to a Hue Family - take your pick!

Don't overlook grays that have a lot of blue in them.

Marylee, on my screen those three grays look pretty neutral to me, i.e., not blue at all.

I used pilgrim haze and it is a silvery blue.

They are very near neutrals. But they still contain enough Chroma, in that when measured, they can be identified as sitting in the Blue Hue Family.

‘Greys’ are colours with very little Chroma. They are just greyed-out, knocked-back colours.

In some lighting they may appear to many as ‘just neutral’. In other light settings, more of their parent Hue maybe discernible. These types of colours are far more affected by light changes than more colourful colours.

If they feel ‘too grey’ for you (really need to see them as real-life paint chips) then you are looking for colours with more Chroma.

Graytint belongs to the Green Hue Family, but can shift more-grey blue in imbalanced lighting

I painted my masterbath Silvermist #1619 from Benjamin Moore at least ten years ago, and I love it as much now as I did then. It's a very, very easy color to live with. I also have a sewing/hobby room and I think this would be ideal for that use. Here's an old thread asking about favorite blue/gray paint colors. You'll see my bedroom and bath just a few posts down (and get lots of other suggestions too!)

Old Blue/Gray Paint Color Thread

Take a look at SW Gray Screen and Network Gray.

I have painted our main bath SW Mount Saint Anne twice, it is very much how you describe the colour you are looking for.

Sherwin Williams Wall Street is a very gray blue. https://www.sherwin-williams.com/homeowners/color/find-and-explore-colors/paint-colors-by-family/SW7665-wall-street

Try BM Wedgewood Gray. I️ have it in my south facing living room and it reads blue.

Thanks so much for all of your recommendations. I decided to try something different and used Intercoastal Gray by Behr. So far, I am loving it. A few years ago, I would have repainted because it has a bit of lavender/purple in it, but I love it. I'll try to get some photos when it's finished.

GF painted her kitchen Mt Ranier Gray by Ben Moore and it reads blue but has a lot of gray in it...it's a lovely color and goes well with her off white cabinetry.

Enjoying this thread- love the colors here.

I had to look up Intercoastal Gray and I think it's beautiful! ( and, it's really nice that Behr includes LRV on the first screen. Talk about handy dandy.

Earlier on my own, just flipping through a SW paint deck that I have, I really was liking North Star ( quite a bit lighter though)

A lot of blues read “baby blue”. SW Copen Blue is blue/green/gray.

I chose a grey color for my master bedroom based on wanting something that was neutral enough to not clash or highlight my orange toned wood trim, and also match with a lot of other wood finishes. I used Sherwin Williams "Grey Screen" which ended up reading a tad blue, particularly when other blue accents are in the room. I like it though, it is neutral enough to make a great background wall color for all kinds of wood furniture in there, bedding and art.
