Sherwin Williams Halcyon Green (SW 6213): A Bold Review

Sherwin-Williams Halcyon Green is a soft, muted blend of blue and green that designers have relied on for years, and it’s easy to see why.

It brings to mind quiet coastal towns, breezy Southern porches, and the relaxed charm of vintage interiors. I’ve used Halcyon Green in many client projects, and it keeps winning me over with how well it works in almost any room.

Here’s what makes Halcyon Green one of my go-to colors, from its undertones and LRV to the best rooms and pairings.

Understanding Halcyon Green: A Perfect Balance

1. What Is Halcyon Green?

Halcyon Green (SW 6213) is a soothing blend of blue and green with subtle gray undertones. Its muted appearance gives it a calm, balanced feel, making it a lovely choice for spaces where you want a little color without overwhelming the room.

At first glance, Halcyon Green may look more blue than green. However, its green undertones add warmth and an earthy touch, keeping the shade from feeling too cool or stark. If you prefer something earthier, Sherwin-Williams sage green paint colors offer softer alternatives.

What makes Halcyon Green stand out is its understated character. Unlike brighter shades, it feels gentle and relaxed, allowing it to complement a wide range of interior styles, from traditional to modern.

Note: I once used Halcyon Green on a client’s bathroom vanity, and it added just the right amount of personality without overpowering the space.

2. Light Reflectance Value (LRV) of Halcyon Green

Halcyon Green has a Light Reflectance Value (LRV) of 39, placing it in the mid-range category. LRV measures how much light a color reflects on a scale of 0 to 100. Lower values indicate darker shades, while higher values represent lighter ones.

With an LRV of 39, Halcyon Green adds depth and character without necessarily making a room feel dark or cramped. Its appearance depends on natural lighting and surrounding colors.

3. Halcyon Green Hex Code and RGB Values

If you’re planning a room digitally, Halcyon Green’s hex code is #9BAAA2 and its RGB value is 155, 170, 162. These values help you preview the color in design apps, mood boards and online room visualizers, and they’re handy when you’re trying to match fabrics, tiles or decor to your paint.

Keep in mind that screens show colors differently depending on brightness and display settings. Use these values for planning, but always check a physical paint sample on your wall before you buy.

4. Is Halcyon Green Warm or Cool?

Halcyon Green is a cool blue-green. Its green and gray undertones keep it from feeling icy, but it still leans cool. You’ll probably notice this most in north-facing rooms, where the light is already cool.

If you want it to feel cozier, balance it with warm elements. Warm white bulbs, natural wood tones, and cream or beige textiles all soften its coolness and make the room feel more inviting.

How Lighting Influences Halcyon Green

If there’s one thing I always warn people about with Halcyon Green, it’s lighting. I’ve seen the same shade feel completely different from one room to the next, so knowing your light makes all the difference.

Lighting can change how Halcyon Green looks throughout the day. I recommend testing large samples under natural and artificial light before painting. Check different walls, compare nearby finishes, and observe how its blue-green undertones shift.

Lighting or Test	Effect on Halcyon Green	What to Do
North-facing light	Highlights cooler blue tones.	Expect a calm, muted look.
South-facing light	Enhances warmer green tones.	Check in bright sunlight.
East-facing light	Creates a soft morning glow.	Test in the morning.
West-facing light	Adds warmth and richness.	Check in late afternoon.
Warm bulbs	Bring out green undertones.	Test for a cozy feel.
Cool bulbs	Emphasize blue undertones.	Check for a crisp look.
Layered lighting	Adds depth to the color.	Test with multiple lights on.
Sample placement	Light and surroundings affect appearance.	Test different walls, away from white trim initially.
Time and finishes	Color shifts with light and nearby materials.	Check morning, afternoon, and night; compare flooring, cabinets, and fabrics.

Best Applications for Halcyon Green

Halcyon Green is flexible enough for many spaces, but a few rooms really bring out its best side. Here’s where it shines most, along with simple ideas to help it look polished and feel right at home:

1. Living Rooms

In living rooms, Halcyon Green works well on a main wall, an accent wall, or built-ins. It gives the space color and depth while staying quiet enough for a room where you relax, host guests, and spend most of your evenings.

Its muted tones pair easily with different furniture styles and decor accents. Add cream or beige throw pillows, wooden coffee tables, and metallic accents to create a balanced, cohesive look.

Note: I once used Halcyon Green behind their bookcase, and it made the books and decor stand out beautifully.

2. Kitchens

Kitchens are where Halcyon Green often gets the most attention, especially on cabinets and islands. Among the many green paint colors for kitchen cabinets, it brings a muted blue-green look that works beautifully beside stone, tile, and metal finishes.

Its muted tones offer a sophisticated alternative to traditional white or gray cabinets. Pair Halcyon Green with white quartz countertops, brass hardware, and subway tile backsplashes for a coastal-chic feel.

3. Bedrooms

In bedrooms, Halcyon Green works on all four walls or just behind the headboard. Its soft, low-contrast tone suits a room you use to wind down, and it never feels overwhelming as the first thing you see each morning.

Its soothing qualities help create a calm, peaceful atmosphere. Combine it with crisp white bedding, soft gray rugs, and natural wood furniture for a harmonious look.

4. Bathrooms

Bathrooms are often all white and gray, and Halcyon Green adds color without breaking that clean feel. It pairs naturally with water, stone and soft lighting, helping a small room feel fresh and spa-like rather than plain or clinical.

Halcyon Green works well on vanity cabinets, accent walls, or wainscoting. Pair it with marble countertops, brushed nickel fixtures, and soft white towels for an elegant touch.

Using Halcyon Green Outdoors

Halcyon Green brings a soft, welcoming touch to home exteriors. I think it works especially well on exterior walls, porch ceilings, and front doors. Its muted blue-green tones complement natural materials, neutral siding, and contrasting hardware.

Outdoor Area	Why It Works	Best Pairings
Exterior walls	Creates a soft, classic look.	White trim, charcoal gray, stone, and brick.
Porch ceilings	A subtle alternative to haint blue.	White or cream walls and railings.
Front doors	Adds color without overwhelming.	White, cream, or gray siding, red brick, and brass or matte black hardware.

Colors Similar to Halcyon Green

If you like Halcyon Green (LRV 39) but want something lighter or from another brand, a few shades come close. Most of the difference comes down to how light or dark each one reads, so my first advice is always to test them in your own light before deciding.

1. Sea Salt

Sea Salt (SW 6204) is the shade I hear compared with Halcyon Green most often. With an LRV of 63, it’s much lighter and airier, and it leans more green-gray than blue-green. My rule of thumb: choose Sea Salt if you want the whole room to feel soft and open, and Halcyon Green if you want the color to actually be noticed.

• Choose Sea Salt: For whole rooms, smaller spaces, or rooms with little natural light.

• Choose Halcyon Green: For cabinets, accent walls, or rooms where you want deeper color.

2. Rainwashed

Rainwashed (SW 6211) sits on the same Sherwin-Williams color strip as Halcyon Green, so the two share a similar blue-green character. With an LRV of 59, it’s the lighter, brighter version, and it’s the first shade I’d try if your Halcyon Green sample looks too heavy in your room.

• Choose Rainwashed: When you love the look but your room feels too dark for a mid-tone.

• Choose Halcyon Green: When Rainwashed looks too pale and you want more depth.

Another shade worth comparing is Sherwin-Williams Coastal Plain, which offers a warmer, more noticeably green alternative to Halcyon Green’s muted blue-green appearance.

3. Benjamin Moore Alternatives to Halcyon Green

There’s no exact Benjamin Moore version of Halcyon Green, though color-matching tools list Greyhound as one of the closest options. If you’re set on this exact look, I’d skip the near matches and have your paint store color-match the code instead.

• Closest Benjamin Moore option: Greyhound, commonly listed as a near match.

• Exact match option: Ask a paint store about matching SW 6213 in a Benjamin Moore or another manufacturer’s paint. Keep in mind that the result may not look identical.

• Before you buy: Compare samples side by side, since no near match is perfect.

Perfect Color Pairings for Halcyon Green

Halcyon Green is easy to pair because its gray undertone keeps it calm and balanced. I prefer it with soft neutrals for a quiet, relaxed look, and with deeper or warmer shades when a room needs more contrast and energy.

1. Neutral Companions

Soft neutrals let Halcyon Green stay the star of the room while keeping the space light. Whenever I’m unsure what to pair it with, a clean white or a light gray is where I start, because they make the blue-green look crisp and intentional.

Sherwin-Williams Pure White (SW 7005) works well on trim, ceilings, and moldings without feeling stark. Repose Gray (SW 7015) is a soft, light gray that pairs nicely with Halcyon Green on walls in nearby rooms.

2. Bold Accents

A bolder accent creates contrast and makes Halcyon Green feel richer. I’d use these in smaller doses, like on a door, an island or a single piece of furniture, so they support the main color instead of competing with it.

Use Naval (SW 6244), a deep navy blue, for a polished look on doors or kitchen islands. Copper Pot, a warm terracotta shade, works beautifully on furniture or smaller accents, balancing the color’s cool undertones.

3. Best Metal Finishes and Hardware

Metal finishes can quietly change how Halcyon Green feels, especially in kitchens and bathrooms. My favorite is warm brass, which softens its coolness, but darker finishes work well if you want a more modern look.

Metal finishes can change how Halcyon Green feels, especially in kitchens and bathrooms. Brass and gold add warmth and classic elegance, while copper complements earthy decor. For a more modern look, matte black hardware creates a stronger contrast with the soft blue-green walls.

Expert Tips for Using Halcyon Green

These are the small details I always check before using Halcyon Green, since they’re easy to overlook but make a big difference to the final look.

• Choose the Right Finish: Use matte or eggshell on walls, and satin or semi-gloss on cabinets and trim for durability.

• Coordinate with Flooring: Natural wood or soft gray floors keep the space cohesive and airy.

• Add Natural Textures: Wood, stone, wicker and earthy textiles bring out the color’s warmer side.

• Watch Surrounding Colors: Darker neighbors bring out its blue, while warmer shades highlight its green.

• Mix Styles Freely: It suits classic furniture and sleek modern decor equally well.

• Try It in Unexpected Spaces: A laundry room, pantry or mudroom adds charm to areas that are often overlooked.

• Paint a Piece of Furniture: A dresser, bookcase, or side table brings the color into a room without touching the walls.

Sherwin-Williams Halcyon Green is a calm, muted blue-green that has stayed a favorite in coastal and traditional homes for years.

Whether you’re updating your interiors, refreshing your exterior, or simply trying something new, this shade gives you plenty of ways to bring soft color into your home.

It’s the kind of color that feels quiet at first and becomes more interesting as you notice how it changes with the light. For me, that’s a big part of its charm.

The best way to know if it’s right for you is to see it on your own walls, so order a sample and let your light decide.
