The 10 Best Blue-Gray Paint Colours: Calming, Relaxing and Cool

The Top 10 Beautiful Gray-Blue Blend Paint Colours

Blue-green blends have had a good run. And while they’re certainly still running (Forrest Gump style), I’ve been getting a LOT more requests for blue-GRAYS in the last few months.

Why is gray-blue all of a sudden one of the popular kids? Well, I think that psychologically, a lot of us are looking for calm. We’re pining for colours that bring our heart-rates down and help us relax in our homes…which we’re spending an AWFUL lot of time in these days. Gray-blue seems to be a magical blend that hits a certain happy place (not THAT one, you dirty bird). Personally, my happy blend is a mixture of white wine, red wine, and Boom Chicka Pop Popcorn, but each to their own.

The thing to remember with blue-gray is that it’s rarely just blue-gray. Just like gray will have undertones, blue also loves to flex its colourful muscle (which I wrote MORE about HERE if you’re curious). So, even when the blue in your gray is an UNDERTONE, it can also have an undertone of its own tucked inside its deep lil’ pockets.

AND REMEMBER, when it comes to choosing a gray-blue, don’t just choose the one that YOU like, you also need to consider the ones that best suits the products, exposure, and finishings in your room, even if they fall a bit outside of your personal comfort zone.


A blue-gray with green is STILL a cold colour, as blue and green are traditional cool colours, however, green can soften the look of blue. This won’t make it WARMER, but it can look a bit more inviting compared to a colder blue blend (however, that IS open to perception).

  • add even MORE green and you’ll get sage green, which is a COOL green (literally and figuratively)
  • these types of gray-blues are often referred to as beachy, coastal or spa-inspired


A blue-gray with purple tends to look a bit cold, which makes sense as purple is most often viewed as a cool colour. When you add purple to blue (technically you’re adding red, but I’m pretty meat n’ potatoes around here), you’re going to shift your blue, making it look a bit cooler.

  • add ENOUGH purple and you’ll get periwinkle
  • a gray-blue with purple is often seen as more romantic and slightly more traditional than the coastal vibe found in gray-blue-greens

And while these are ALL COLD COLOURS, you can definitely adjust the type of blue you see by choosing which way it leans!

Now, in my experience doing Online Paint Colour Consulting, the requests for a blue-gray with a GREEN undertone greatly outweigh the blue-purple end of things. Why? Well, I think generally, blue with a green undertone is a bit easier to coordinate products and furnishings with, having a bit more flexibility compared to blue-purple undertones. I’ve also found that with blue-purple, the purple seems to take over really quick, whereas the green can seem much more passive when tucked inside of blue.

Now that we have THAT out of the way, let’s check some of these bad-boys out!

1. Benjamin Moore Gibraltar Cliffs 1587

Hands-down, my FAAAVE blue-gray blend. Gibraltar Cliffs is a gorgeous, stormy blend of blue and gray with a minor green backdrop. This is one colour that’s REALLY open to interpretation as I’ve had people say it’s GRAY and others clearly see the blue. So, it will be up to you as to how it sits in your eyes!

See more of this HERE

A bit more about Gibraltar Cliffs…

  • Gibraltar Cliffs has an LRV of 30.63, so while it’s got some depth to it, it’s not a terribly heavy colour. Not sure what LRV is? It could save your paint lovin’ life – Read HERE
  • If you love the idea of blue but aren’t quite ready to commit to it full-time on your walls, Gibraltar could be the answer – makes for a GORGEOUS feature wall!

If you like Gibraltar Cliffs, you might also like…

  • Sherwin Williams African Gray, which calms things down CONSIDERABLY and removes almost all of the green
  • Benjamin Moore Stonybrook, which we’re going to hit next…

2. Benjamin Moore Stonybrook 1566

Stonybrook is definitely a colour ninja. Not that it can go purple, it’s definitely a blue-green blend, but the green can take over OR it can settle back down, leaving more blue on the table (or on the wall, really…)

You might see a bit more of the gray-blue here…

Any colour can change its tune (or tone) based on the exposure of the room, which goes back to one of my most POPULAR blog posts – North, East, South, West: Which Paint Colours is the Best? You may want to brush up on your exposures before finalizing your paint colour choice.

A bit more about Stonybrook…

  • With an LRV of 28.23, Stonybrook sits in the solid medium-toned end of things.
  • Stonybrook is like a darker Mount Saint Anne, which we’re going to touch on shortly. However, as this colour darkens the green starts to rise up more, ALMOST crossing the line between gray-blue with a soft green to being a relatively balanced gray-blue-green blend

If you like Stonybrook, but want to swing things a bit less green, take a look at…

  • Benjamin Moore Shaker Gray. Mmmm, I’ll shake it any day for some Shaker Gray.
  • Benjamin Moore Gibraltar Cliffs, which we talked about earlier. I’d shake it for Gibraltar Cliffs too, but the cliff is pretty high and I don’t want to fall off (once this booty gets a goin’, there’s no stopping it – wink wink).

3. Sherwin Williams Network Gray SW 7073

Network Gray is a really great ‘on the border’ gray. It does have a blue undertone and while this undertone can lean JUST slightly into green, it can also flex the other way, especially if you have north-facing light.

A bit more about Network Gray

  • Network Gray has an LRV of 37, so it’s lighter than Gibraltar, more of a standard medium-depth colour
  • Network Gray really is a gray with undertones, the colour isn’t obvious enough to take over unless you’re sensitive to colour

If you like Network Gray, you might also like…

4. Sherwin Williams Lullaby

While I don’t have photos of this one yet, Lullaby is a GORGEOUS colour that leans MORE on blue and a bit less on gray compared to the others.

A bit more about Lullaby…

  • Lullaby has an LRV of 65, parking it nicely in the light range.

5. Sherwin Williams Jubilee

Jubilee is one of the best blue-gray-purples as the blue still shows up enough to the party without the purple going too dominant.

A bit more about Jubilee

  • Jubilee has an LRV of 45, so just a nice moderate medium-toned paint. If you still haven’t read up on LRV – TWO SLAPS WITH A WET NOODLE (here’s the link)
  • Jubilee has quite a lot of colour in it. Some people would still say it’s gray, while others would say it’s quite clearly a colour

If you like Jubilee, you might also like…

  • Sherwin Williams Uncertain Gray. Uncertain Gray is a bit grayer and slides back to being a blue with a very minor green in it, although in the right light it’s a bit of a swinger and could switch partners, leaning a touch purple
  • Sherwin Williams Let it Rain
  • Benjamin Moore Gray Timber Wolf, which is lighter and softer, but again, watch as it can swing more into purple
  • You’ll also want to compare Jubilee to this NEXT gray-blue blend – STARDEW!

6. Sherwin Williams Stardew

Stardew is flat-out gorgeous. It’s more blue than it is gray and while it’s pretty flexible, it could nod just a wee wink into green…barely.

On a side note, did you know that the photos on my blog are 100% powered by my Online Colour Consulting clients? Thank you all for sending them in! This is also why I might not ALWAYS have photos of just the colour I want to tell you about, but will add them as they come in.

7. Sherwin Williams Tinsmith

Tinsmith is one of the more muted and lighter ones on this page. It’s a light-medium super STORMY gray with a soft blue undertone, it’s definitely a ‘gray’ with blue in it, whereas some on this page will look more blue than gray. And just like Network Gray, you’ll find it to be a BIT of a ninja re: the purple/green factor.

Look how much it changes with lights on!

A bit more about Tinsmith

  • Sherwin Williams Tinsmith has an LRV of 57, so it’s a light depth paint colour, but it’s a HEAVY light, not a fresh bright one
  • Tinsmith has slightly more noticeable undertones than what you’d see in a traditional gray paint colour

Let’s take a quick break to talk about paint samples…

Undoubtedly, you’ll be heading out in the near future to grab paint samples – stop right there! I want you to check out SAMPLIZE. Samplize offers peel and stick paint samples that are more AFFORDABLE, EASIER and more ENVIRONMENTALLY FRIENDLY than traditional paint pots. Here are just a FEW reasons why I recommend Samplize to my clients…

  • Samples arrive ON YOUR DOORSTEP in 1-3 business days, depending on location
  • At $6.99, they’re more affordable than the samples pots/rollers/foam boards that are needing for traditional paint sampling
  • If you keep the samples on their white paper, you can move them around the room

Visit the SAMPLIZE website HERE

If you like Tinsmith, you might also like…

  • Sherwin Williams Silverplate. Still a light-medium gray, but a bit more stormy with less undertone
  • Benjamin Moore Stonington Gray, read its awesome colour review HERE

8. Benjamin Moore Mount Saint Anne

Mount Saint Anne is one of the good ole boys girls. Anne is a soft, medium-toned blue with a good shot of gray in her and a passive green.

A bit more about Mount Saint Anne…

  • MSA has an LRV of 42.28, so she’s a medium depth colour

If you have a room with north-facing light and are finding the gray-blues a wee bit nippy, try choosing one with a BIT more colour to it, like Mount Saint Anne. The increased chroma/colour can help offset the gray light coming in the windows.

If you like Mount Saint Anne, you might also like…

  • Benjamin Moore Beach Glass, the lighter, softer and juuuust slightly greener version
  • Benjamin Moore Adagio, a softer look with a bit more gray and very little green

9. Benjamin Moore Colorado Gray 2136-50

Colorado Gray is the most COLOURFUL gray-blue on the page, making it more of a dominant BLUE-gray. And it does lean into green, not drastically, but enough to be slightly noticeable.

A bit more about Colorado Gray

  • Colorado Gray has an LRV of 44.4, making it a nice moderate, medium-toned colour
  • Colorado IS A BLUE PAINT COLOUR, no foolin’ around with this one thinking it will look gray

10. Sherwin Williams Niebla Azul SW 9137

Niebla Azul is a light-medium depth blue paint colour with an LRV of 53.

A bit more about Niebla Azul

  • With an LRV of 53 and a slightly higher chroma, this is a great colour for a secondary room, but would be too much blue for a ‘whole home‘ application
  • Niebla Azul commits to it’s blue and doesn’t HEAVILY favour blue-purple or blue-green (only MINORLY blue-green)

If you like Niebla Azul, you might also like…

  • Sherwin Williams Jubilee – leans slightly more blue-violet
  • Sherwin Williams Lullaby – similar idea, but lighter

  1. Hi Kylie
    I too am looking for a grey blue to complete my kitchen/family room makeover. I have looked at SW Tinsmith and BM Stonington Grey but also really like SW Zircon and wonder how this colour compares to those.
    Love your posts. I’ve gotten so much great advice from them.

    1. This was an incredibly helpful article. What paint color is in the first photo, the corner of the wall with the circular black mirror and white wainscoting underneath?
      Thank you!

  2. Hi, Kylie – Great article. By the way, I painted the wall behind my bed with Trout Gray and I LOVE it. I also used Trout Gray on a wall with a fireplace, in order to make the fireplace less conspicuous (similar to how you used a dark SW shade – was it Cyberspace? – on the wall with your tv in your prior house, I think).

    1. Post

      Seriously, I love Trout Gray SO MUCH! Which is my passive-aggressive way of saying…SEND PHOTOS! ;). If you want to snap some, you can send them to [email protected] If that’s not your jam, that’s cool too!

  3. Kylie, your site is amazing! Quick question, the Gray 2121-10 (totally agree with your rant!) fireplace pic…what is the coordinating wall color?? And if you were to do it in a dining room as a top/bottom division with a chair rail, do you think the dark would be best on the top or bottom?? My trim is Chatilly Lace 🙂 Thank you so much!!

  4. Under what circumstances would Gray Timberwolf scream purple? If I missed that in your article I apologize! BTW, I’m using Newburyport Blue in my kitchen with oak cabinets, brushed nickel hardware, white subway tile, light countertops and white appliances. Trying to do the best with what we have therefore not replacing or painting the cabinets…but we will be investing in better lighting! I love that blue! So colorful! And we used Icy Moon Drops in our girls’ room and it’s so fun and fresh (like my baby girls)! Thank you for helping us folks that are clueless when it comes to color!

    1. Post

      Well, I find that my clients usually lean into colours with a BIT more gray to them OR a bit more depth. I’m not saying no, but I haven’t come across it before ;).

      1. Hey Kylie,
        Thanks so much for this article! I’m also looking for the paint color in the very first picture but two of my Sherwin Williams paint specialists said it was not Network Gray. 🙁 Any recommendations as to what this color is or is it just distorted blueish in the photo? Network Gray seems to be way more on the “gray” side and not blue side. ?? 🥴 Sorry for the confusion!

        1. Post

          Hi Joanna, well, that was a hands-on project and I can tell you with ALLLL certainty that it was indeed Network Gray! The thing is, every gray has undertones and Network Gray has MORE than usual, so it’s not a great ‘neutral gray’ look and you can definitely see more blue at times. This can also shift depending on your exposure/interior finishes. Grab a paper chip sample of Dorian Gray, which is a more neutral gray (a warm one with its own undertones). This might show you HOW BLUE Network Gray can look!
          I hope that helps :). Let me know!

  5. We used SW misty in our upstairs loft. It is beautiful for that area. It is kind of like the color of faded blue jeans and a bit moody. I tried it downstairs but it looked muddy on every wall I tried.

  6. Hi Kylie,

    I’m reading all your articles for help with choosing my front door color and they have been extremely helpful. I want a blue green door but don’t think the greens work with my pavers which are more icy and I think have more purple. My paint is willow creek, also a purple undertone, and I have red/pink brick for my doorsteps. Should I lean into (see I’m using your phrases!) more of a purple blue? Also I have no direct sunlight (recessed front door faces north-north east) so everything I try in the blue green greys look, well, grey. Any suggestions are very appreciated! Thank you.

    1. Post

      Hi Kiley! I haven’t seen your home, but from the SOUNDS of it, you might check out Benjamin Moore Gray 2121-10 (you need the number to find it). Or it might at least get you on a better track ;).

    Which white colour for trim would you recommend for Colorado Gray in a south facing room ?
    Thanks so much !
