How to Choose the Best Blue Paint Colour

How to Choose the Blue That’s Right For You! 

Are you hunting for the best blue and not just any hue will do? Then you’ve come to the right place!

Blue is a popular paint pick for MANY reasons. It’s calming, classic, coastal, country – subtle, striking and sensual, but the one thing it isn’t? Easy to pick.

And while I’ve written a blog post about the best blue and blue-green paint colours, we need to have a lil’ chat before you whip out your paintbrush. Why? Because while they may seem simple, all blues are NOT created equal…

True Blue

Short of going ‘primary blue’, it can be hard to peg down a true-blue, particularly once you start mixing in gray.

A colour like Newburyport Blue is more likely to give a ‘true-blue vibe’ without going right into the primary range.

Blue with purple undertones

These are blues that lean slightly more toward purple, without committing all the way. These blues often feel a bit cooler than neutral or softer blues. Technically, these are blues with a touch of red in them, and you know how technical I am (wink wink).

In our last home (above), it was a toss-up as to whether our guests thought the paint colour was blue, blue-purple or gray!

Blue with green undertones

Not I’m not going to say that blue/greens are WARM, but they are definitely a bit softer and more inviting looking than blue-purple colours. Technically, these are blues with a touch of yellow in them.

In the above 2 photos of Silver Marlin, things look pretty darned green in spots!  However, this is a combination of lighting and exposure, as Silver Marlin is a beautiful blend of blue, green and gray!

And why does all of this matter? Because you want to make sure that you pick the type of blue that you like and avoid the ones you don’t. If you don’t like purple, there are a whole WHACK of blues that you’ll want to avoid, blues that you might not have known lean to the purple side if I hadn’t warned you – same thing for green.

And how you do figure out what type of blue you like?

  1. Ask the paint store which side of the blue-scale your fave sits on
  2. Compare. Pick your FAVE blue or two, and then pick up the colour chips directly to the left and right (trusting that your paint store arranges them this way). This will REALLY help to show you how the undertones shift from one to another. If they aren’t arranged that way, just grab 4 or 5 blues that you generally like and compare them to each other, this might help you see the shift in undertones

The above photo shows 3 of the more popular blue choices.

LEFT: Blue-Purple. This has colours such as Windy Blue, Bracing Blue and Indigo Batik on it.

CENTER: Blue (wink of green). Definitely a popular strip, including the colours Languid Blue, Tempe Star and Whirlpool. As this strip gets darker, the green comes up more.

RIGHT: Blue-Green. The TOP blue strip these days, including hits like Tradewind, Rain and Moody Blue.

And of course, for each one of those colour strips, there are MORE comparables that take things more purple/blue/green – it just depends on which direction you’re heading in!

Blue and north-facing rooms

If you are wanting to paint your north-facing room a beautiful blue, you need to tread carefully. Northern exposure is a cool gray/blue light. Adding blue to the walls will only compound the ‘cool look’ of the room and northern light also enhances cool colours slightly.

If you’ve fallen in love with a more cool-toned blue, you’ll need to do some serious interior work with lighting, accents and texture to add some balance to the space.

However, if you are seeing what I’m explaining and are worried about that cool edge, consider a blue leans into green/gray, so that it’s a bit softer looking.

Blue and south-facing rooms

Unlike a north-facing room, a southern room just loooooves blue. Why? South-facing light is warm/yellow and painting a southern room a warm colour only packs on the heat! By painting the walls a cool blue tone, you’ll help to balance out the warm sun rays and add some serious colour balance to the space.

However, it’s important that you really LOVE blue, as in the evening, you won’t have that warm sunshine to balance things and will have to rely on your interior lighting to add the balance.

Blue and Light Bulbs

Warm temperature light bulbs: When there isn’t any daylight, you might find that warm bulbs (particularly old-school bulbs) can cast a yellow/gold glow on the walls. When this mixes with blue, it can create a kind of blue/green blend.

Daylight light bulbs: While personally, I find daylight bulbs a bit too crisp for everyday living, they can be nice in a bathroom.

Daylight bulbs will really show your blue at its most true, but keep in mind that it isn’t a warm, friendly-looking light. I’ve found that men often prefer daylight bulbs, whereas women often like the softness of a warmer light.

Cold temperature light bulbs: There is not a single room that I would recommend these for – nadda.

What are the best trim colours for blue paint?

There are 3 ways to paint your trim when you’re using blue.

  1. Cool white
  2. White
  3. Warm white

White: Choosing a simple white is often the safest bet when you’re painting with blue, but it ALL depends on your décor style and other features such as any white cabinets/existing whites

Warm white: A warm white will slightly contrast with the blue, creating a really pretty combo as long as you don’t go TOO warm on the white, subtle and simple is best!

Cool white: Cool whites can keep up the crisp, clean, cool vibe of your blues

  1. I love the look of Benjamin Moore Stonybrook! Would it tend to go more green or blue with northwest light?

  2. Hi there ! Great timing on this e-newsletter as I’m literally at the point of choosing a lovely blue to carry throughout my home. Can you tell me what paint colour was shown in the picture just under the three whites please ? It’s absolutely gorgeous. I’m assuming that the paint colour in the hallway would be something like a BM Navajo White or the sort, right ? It appears to be a bit more on the creamy side than the painted trim. I’m utterly in love with that picture ! Thanks for your input.

      Hi Christianne, that was SW Wall Street, super gorgeous, eh?! And that hallway is SW Wool Skein which I just did a colour review on last week!

  3. Hi, Can you tell me the difference between BM Tranquility and SW comfort grey? Thinking of painting our master bedroom one of these colors. Thank you!

    1. Post

      Hi Wendy, they are SO similar, Comfort Gray leans just a wink more green, but really it would be hard to really clarify the exact difference. Normal BM or SW colours are usually made up of 3-4 colours, whereas BM’s AFfinity line can have 7-8, meaning they are far more complex and prone to change throughout the day – and Tranquility is one of those!


  4. Hi Kylie, Love your website!! You are so talented!! I am looking for a soft blue (LRV 60s) paint color with no green undertones for a west facing master bedroom. Our furniture is medium brown sleigh bed style and our linens are white. Do you think BM Beacon Gray would work? Any other thoughts? Many thanks!

  5. Hi Kylie,
    I am in Australia and embarking on colour for a new home. I have a few hurdlles to conquer (slate floors). Are you able to advise on an e design course or are yhe ptoducts too different here?

    1. Post

      Hi Natasha! I think the problem I came across with Australia before was that you only had CIL dulux paint. If you happen to have a Benjamin Moore or Sherwin Williams, I can definitely help, and understand that the exposure are reversed compared to where I live 😉 We also use a lot of slate up here in Canada, so I’m familiar with many of them…

  6. Any suggestions for a gray blue for living room dining room, kitchen and family room, open floor plan.same color, thank you.leaning toward gray

  7. Hi Kylie: I’d very much like a consultation but just wanted to first check which paint companies you use. My painter has a strong preference for Dulux and I didn’t know if you worked with their palette or now. Thanks very much

    1. Post

      Hi Patti! Unfortunately I just use SW and BM. I’ve tried doing it with Dulux but just found their ranges too limiting!

  8. Hi Kylie, whenever we have a psinting job in front of us, I look to your website. Great info and insight!
    We are thinking of painting SW tradewind for our exterior front door and shutters. For the body of the house, what neutral colors complement tradewind? Whites/off whites/beiges? Thanks!

  9. Have you ever used SW Mild Blue? Wondering what your opinion is on it as a nursery color with white trim and ceilings. We don’t want something too bold or gray that looks gloomy. Hoping for a nice peaceful, blue/gray that looks relaxing!

  10. I really love love your blogs and videos! With that said, I have a bedroom facing South South West. Room size 10×12 with one tall window mostly facing South West with oak trees outside. This room is connected to another room with a bathroom between. These room do not face each other but you can see them both when your in the bathroom. The wall color in the other bedroom is a BM Manchester Tan and the hallway leading to these two rooms are BM Bennington Gray (a designer helped with this many year ago). I need to refresh this current bedroom and the bathroom that join the two rooms together.

    All the colors mentioned are definitely on the warm side but I do want to incorporate some coolness to the bathroom and current room having it all make sense and so there still is a good flow.

    The bathroom is very small with one window above the toilet facing the west only. The midday sun is over the house and there are trees in the neighbors yard. This bathroom does see both rooms. I would like to lighten it up with some softness and character. I was looking at SW Lullaby and SW North Star and SW Upward. I don’t want a pure blue room totally but don’t mind the undertones. It can look like a light blue but something pretty and soft with shade and sun.

    The connecting bedroom, I am struggling with. I definitely do not want creamy or green. Green comes in very strong when room in shaded from the trees outside. I need the color to flow to the hallway (BM Bennington Gray). I can’t have the color to close to the hallway color, its too much. So need more a neutral with a coolness perhaps to blend with bathroom hallway. Not asking for much am I, haha. I really need help. I have watched the videos and read your blogs and keep getting paint swatchs and putting them on white background but am feeling I am not getting any closer. Oh, I only have a ceiling fan with a light kit in this room with warm light. when there is shade, there is shade in both rooms.

    I am praying you can help with suggestions on both rooms. The trims are a crisp white, extra white.

    Thank you so much.

  11. A couple years ago when we bought our house, I could swear I read a post where you described a light blue as…if light blue could be navy blue… but I can’t find it again. Am I crazy?
