A Crisp Coastal Color Palette: Benjamin Moore Chantilly Lace, Horizon Gray & Hale Navy

There is something about a coastal-inspired home that just feels good. The light, the calm, the way every room makes you want to put on linen and pour a cup of tea. And while you might think the secret is a beachfront view (helpful but not essential), the real magic is almost always the colour palette.

Today’s combination is a quiet showstopper: Benjamin Moore’s Chantilly Lace, Horizon Gray, and Hale Navy. Three colours that, together, capture everything we love about coastal style. Fresh and breezy without being too literal. Sophisticated without being precious. Calm without being boring.

Whether your version of “coastal” is a Hamptons-style home, a New England cottage, a Cornish seaside escape, or just a city flat that dreams of the sea, this trio works beautifully.

Coastal Color Palette

So, why do these three play so well together, and how to put them to work in your own space?

Chantilly Lace (OC-65)

Think of Chantilly Lace as the clean, crisp white you have been searching for. It is bright, fresh, and slightly cool, with a tiny whisper of grey that keeps it from feeling stark or sterile.

It is classified as a cool white with subtle gray undertones, which prevent the color from appearing overly stark. In coastal interiors, this is exactly the white you want. It bounces light around like it is paid commission, and it makes every other colour in the room look better.

Use it on walls, ceilings, trim, doors, and even cabinets. It is one of those rare whites that works almost everywhere.

Horizon Gray (2141-50)

Now this is where it gets interesting. Horizon Gray sounds straightforward, but it is actually one of those beautifully complex paint colours. It is gray with just a hint of green, a muted shade that evokes a misty harbour setting, adding a welcome dose of tranquility to any room.

That faint green in the grey is what makes it sing for coastal palettes. It calls to mind sea fog, weathered driftwood, and those soft grey-green stones you find in tide pools.

It is a medium-toned colour with an LRV of around 50, so it has enough depth to feel grounded but enough lightness to keep a space feeling airy. Use it as your “second wall colour” when you want a soft, sophisticated alternative to white.

Hale Navy (HC-154)

The undisputed star of countless coastal interiors, Hale Navy is a rich, classic, deeply confident navy blue. Not too purple, not too black, not too bright. It is the colour of a clear evening sky over the water, or the hull of a beautifully kept sailing boat.

This is your drama. Your contrast. The colour that takes a soft, breezy room and gives it backbone.

Use it sparingly and it sings. Use it everywhere and it can swallow a room, so be intentional.

Why This Palette Works for Coastal

Coastal style is often misunderstood as a heap of nautical clichés: anchors, lighthouses, fish-print cushions, and the world’s saddest “Live Laugh Love” sign with a starfish on it.

The actual look is much quieter. It is about light, air, natural materials, and a colour palette that echoes what you see when you look out at the water.

That is exactly what this trio delivers;

• Chantilly Lace mimics sea foam, bleached shells, and bright morning light.
• Horizon Gray captures driftwood, sea mist, and the soft grey-green of beach grass.
• Hale Navy is the deep water and the sky just after sunset.

Put them together and you get a colour story that feels truly seaside, without needing a single nautical print to make the point.

How to Use the Three Together

It’s important to note that you should always buy samples and use them in your home. The above image shows the paints I sampled in my kitchen, which is north-facing, but gets lots of natural light with a skylight and wall-to-wall bifold doors.

But look at how different the colors are from the dollops I’ve saved from Benjamin Moore’s website. Horizon Gray reads much more gray on my screen and Hale Navy looks more charcoal black.

In real life, Horizon Gray leans more towards sage green and Hale Navy has a wonderful blue undertone. So ALWAYS check!

How to use:

The trick with any three-colour palette is figuring out the proportions. A useful starting point is the classic 60-30-10 split:

• 60% Chantilly Lace for your walls, trim, and ceiling. Let this be the background hum of the room.
• 30% Horizon Gray for a feature wall, larger pieces of furniture, kitchen islands, or all the walls in a more intimate space.
• 10% Hale Navy for accents: a front door, kitchen cabinets, built-in bookshelves, a powder room ceiling, an upholstered headboard.

You can flex these proportions depending on the room and how much drama you want. A bright sunroom might go heavier on Chantilly Lace, while a moody library leans into the Hale Navy.

Room-By-Room Ideas

Kitchen

Paint the trim, doors and windows in Chantilly Lace, then make the island a showstopper in Hale Navy (and the cabinets if you want to go totally bold). Tie it all together with Horizon Gray on the walls.

Add chrome or nickel hardware, silver pendants above the island and warm wood tones for instant coastal kitchen magic. You can grab a stainless steel, chrome, brass, or custom range hood from CopperSmith®, which will work perfectly in your coastal kitchen.

Living Room

Chantilly Lace on the ceiling, trim and windows, Horizon Gray on the walls, and Hale Navy on the built-ins. I would also go for a dark navy blue on a single armchair to bring it altogether and gray sofas.

The result is layered, grown-up, and very inviting.

Bedroom

Use Horizon Gray on the walls for a soft, peaceful backdrop, Chantilly Lace on the trim and ceiling, and Hale Navy as your accent through bedding, lampshades, or an upholstered headboard.

Throw in some natural linen and a jute rug and you are basically in a luxury hotel.

Bathroom

Horizon Gray on the walls with Chantilly Lace on the trim and doors. Add a Hale Navy vanity with chrome taps to bring the whole palette together.

Finish with a gray bath mat, wood flooring and crisp white towels for a fresh look – finishing with some ocean-inspired artwork.

Front Door

A Navy front door on a house with Horizon Gray siding or shingles and Chantilly Lace trim is a beautiful palette and coastal cottage perfection! Or go with Hale Navy walls, Horizon Gray front door and Chantilly Lace trim.

Materials That Complement This Palette

Paint colour alone does not create a coastal feel. You need the right textures and materials to back it up.

With this palette, lean into natural wood in pale or weathered finishes, plenty of linen in cream and oatmeal, woven baskets and rattan accents, brass hardware and lighting, honed marble or stone for countertops, and chunky sisal or jute rugs for that organic, beachy texture.

Avoid anything too glossy, too synthetic, or too matchy-matchy. Coastal style loves a slightly weathered, slightly imperfect feel.

A Few Final Tips

Always order sample pots and test them on different walls before committing. Light changes everything, especially with colours like Horizon Gray that have subtle undertones. North-facing rooms will pull cooler, south-facing rooms warmer.

Use the same white throughout your home for trim and ceilings to keep things cohesive. Chantilly Lace is a brilliant whole-house white for this reason.

And do not be afraid of the navy. It feels intimidating in a tin but transformative on a wall.

This is a palette that does not chase trends, does not date, and just gets better the longer you live with it. Crisp, calm, and coastal in the best possible way.
