Top 29 Blue-Grey Paint Colors by Sherwin-Williams (My Personal Picks)

The Perfect Mix of Cool Calm and Soft Neutrals

Choosing paint sounds simple… until you’re standing in front of a wall of swatches that all somehow look the same. I’ve been there too, and I know how frustrating it can be to pick a color that looks just right in every room and every light.

Blue-grey is the one that almost always saves the day. It’s cool but not cold. Calm but not boring. It works in homes that feel modern, traditional, coastal, or clean farmhouse.

So here it is: my favorite 29 blue-grey colors from Sherwin-Williams. Not just from a designer’s perspective  but from someone who’s stood in your shoes, held up 12 samples, and thought “which one won’t make me regret this in two weeks?”

Why Blue-Grey Paint Works so Well

Blue and grey are both considered cool colors, but together they do something special. Blue brings peace and trust. Grey adds subtlety and softness. It’s no surprise that a study by YouGov found blue is the world’s most popular color across all age groups and genders (source).

Where I use it most:

• Bedrooms: For a relaxed, easy vibe.
• Living rooms: Especially if you want it to feel light but not stark.
• Cabinets: Gorgeous when paired with gold or black hardware.
• Exteriors: Especially those facing lots of sunlight.

I feel the same about blue-grey  it picks up light in ways that make it subtly shift from hour to hour, and season to season.

My Tips for Picking the Right Blue-Grey

Before we jump to the full list, I want to share what I always tell my clients:

 Light Changes Everything.

• North-facing rooms make blue-greys feel cooler and more “stormy.”
• South-facing rooms add a golden glow that can soften or even dull the blue.

 Warm vs. Cool

• Cool blue-greys lean icy or silvery.
• Warm blue-greys may have a hint of green or even purple in them.

 Finishes Matter

• Flat or matte: Best for walls you don’t touch often.
• Eggshell or satin: More durable, adds a slight sheen. My go-to for most living areas.
• Semi-gloss: For trim, doors, or high-traffic zones.

Now, let’s get to what you came here for!

Top 29 Blue-Grey Paint Colors by Sherwin-Williams

Grouped to help you choose easier  based on tone and where I’ve loved using them.

Pale &Amp; Airy Tones

(Best for smaller rooms, ceilings, or anyone wanting light and calm)

1. Misty (SW 6232) This one always feels peaceful. I love it for bedrooms and hallways. Looks soft in every light. 👉 Feels clean without being cold.
2. Olympus White (SW 6253) Very light, almost off-white with a blue wink. Great for modern kitchens or laundry rooms.
3. North Star (SW 6246) Barely-there blue that changes with the light. I’ve used this in nursery designs — it’s calm and dreamy.
4. Rhinestone (SW 7656) Almost like a whisper of color. When clients say “I want just a hint,” this is what I show them.
5. Evening Shadow (SW 7662) Cool and airy with a little more personality. I like this for bathrooms.

Common Mistakes to Avoid With Blue-Grey Paints

I’ve seen so many people fall in love with a swatch… only to hate it once it’s on all four walls. Blue-greys can be tricky if you don’t watch out for these common missteps:

1. Skipping the Sample Test

Please, always test before committing.

What looks like a soft misty grey in the store can turn into a baby boy’s nursery blue at home — or worse, a cold steel wall.

 What I recommend:

• Get sample pots (Sherwin-Williams sells these for ~$9).
• Paint two coats on a large poster board.
• Move it around your room during the day and night.

2. Not Looking at Undertones

Blue-grey shades come with hidden extras: purple, green, and even taupe undertones. And they will show up  especially near wood floors, tiles, or colored upholstery.

3. Ignoring Light Direction

Light can either warm up or cool down your paint. If you skip this step, your wall might end up looking way different than you imagined.

North-facing rooms = cooler, often bring out the blue South-facing rooms = warmer, can neutralize some of the blue East/West = changes through the day (test in morning and afternoon!)

4. Choosing the Wrong Finish

Blue-grey can look chalky or patchy in the wrong sheen.

 Here’s how I decide:

Flat/Matte: Bedrooms, ceilings
Eggshell/Satin: Living rooms, hallways, kitchens
Semi-gloss: Cabinets, trim, doors

Finish affects how the color reads — especially with natural or artificial light bouncing around.

 5. Letting Trends Pick for You

Yes, I know “Repose Gray” and “Silver Strand” are everywhere on Pinterest.

But the trendiest choice isn’t always the right one for your home, lighting, or feeling. Let your gut (and your sample test) decide. The goal isn’t to impress anyone — it’s to feel happy every time you walk in.

Before You Grab a Paintbrush…

Studio Beige Sherwin Williams is the color I come back to again and again — not just because it’s pretty, but because it feels right. It calms the noise. It matches just about anything. And it helps a home feel pulled together without screaming for attention.

But picking the right blue-grey takes more than just liking it in a photo. You have to see it in your own light, next to your own furniture, in the middle of your own life.

Here’s what I always tell my clients and now, I’m telling you:

Test before you paint. Trust your eye, not just the name.Pick the one that makes your whole body feel a little softer when you look at it.
