Sherwin-Williams Coastal Plain (SW 6192): A Closer Look

Sherwin-Williams Coastal Plain (SW 6192) is a truly captivating, soft green hue, deeply inspired by the tranquility of nature. It exudes a relaxed, almost breezy coastal feel, making it a perfect choice for creating a calm and refreshing atmosphere. This muted, mid-tone green beautifully complements diverse interior styles, from charming beach-style homes and cozy country cottages to any space where you desire a subtle yet impactful pop of color that feels inherently grounded and organic.

Basic Color Profile and Characteristics

Let’s break down the fundamental characteristics of Sherwin-Williams Coastal Plain:

HEX code: #B7C3A6
LRV (Light Reflectance Value): 37
Color family: Mid-tone green with warm, earthy undertones

With an LRV of 37, Coastal Plain sits comfortably in the mid-range. This means it has enough depth to provide a noticeable color on your walls without feeling overwhelmingly dark, while still reflecting a fair amount of light to keep your space feeling open. This inviting shade is proudly part of Sherwin‑Williams’ Coastal Cool palette, a thoughtfully curated collection specifically designed to evoke feelings of peacefulness, renewal, and a breezy elegance. Its balanced nature allows it to function either as a sophisticated neutral backdrop or as a soft, soothing focal point, adapting effortlessly to your specific design aesthetic and the overall mood you wish to create in your space.

Coastal Plain expertly occupies that desirable sweet spot between feeling airy and feeling deeply grounded. It injects a quiet sense of personality and character into a room without ever dominating or overwhelming your walls, allowing your furniture and decor to shine.

Understanding Coastal Plain’s Undertones

The magic of Coastal Plain lies in its subtle yet influential undertones. This shade gracefully carries both yellow and gray undertones, which together contribute to its distinctive mossy, organic quality. These undertones are key to its versatility, preventing the green from appearing overly minty or excessively saturated. Instead, they lend it a nuanced adaptability, allowing it to feel at home in both traditionally cool and warm-toned settings.

In abundant natural daylight, particularly from bright south-facing windows, you’ll observe Coastal Plain revealing a lighter, clearer green tone, often accompanied by a gentle warmth that enhances its organic appeal.
Under the influence of softer white or incandescent artificial lighting, the subtle yellow-beige undertone tends to become more pronounced. This gives the color a richer, more profound earthy appearance, adding depth and coziness to the room.

This chameleon-like quality, where the color shifts subtly with varying light conditions, makes Coastal Plain remarkably adaptable. However, due to this dynamic nature, it is always highly recommended to sample this beautiful paint in your actual space before making a final commitment, especially if your room experiences significant lighting changes throughout the day.

Coastal Plain in Real Spaces: Visualizing Your Home with SW 6192

The true beauty of SW Coastal Plain reveals itself differently depending on the room and the ambient light. Understanding how this versatile shade typically behaves in various settings is crucial for deciding if it’s the perfect fit for your home and lifestyle.

How Coastal Plain Transforms Different Rooms

This soft green-gray paint is widely celebrated for its inherent calm and impeccably balanced tone. Whether applied to interior walls or exterior siding, it consistently imparts a sense of stability and peaceful elegance.

Living Room Elegance

Introducing Coastal Plain into your living room instantly cultivates a soft, approachable, and easygoing atmosphere. Its gentle hue pairs exceptionally well with classic white trim, creating a crisp definition, and looks stunning alongside cozy beige or tan sofas, natural wood furniture, and woven textures. The color subtly enhances the space without ever overpowering it. Instead, it contributes just enough sophisticated character to maintain visual interest while ensuring the room remains invitingly gentle and deeply relaxed, perfect for everyday living and entertaining.

Kitchen and Cabinetry Refresh

Utilizing Coastal Plain on kitchen cabinets offers an amazing transformation, making the space feel instantly clean, fresh, and effortlessly relaxed. It infuses a cool, refreshing vibe that is never stark or cold, but rather inviting. When paired with pristine white counters, elegant gold or silver hardware, and light-toned flooring, this shade maintains a tidy, soft, and utterly pleasant aesthetic. It works equally well in both compact and expansive kitchen layouts, creating a harmonious and uplifting culinary environment.

Serene Bedroom Walls and Accents

This tranquil green-gray color truly shines in bedrooms, where its inherent calmness fosters a quiet, peaceful sanctuary perfect for rest and rejuvenation. Whether used on all four walls or strategically on accent spots, such as behind the bed, it adds a soft, enveloping touch. Complement Coastal Plain with light, airy bedding, warm wooden nightstands, and carefully selected soft lighting to complete a truly peaceful and utterly serene look and feel, promoting ultimate relaxation.

Exterior Siding and Doors Appeal

On home exteriors, Sherwin-Williams Coastal Plain bestows a wonderfully friendly, nature-inspired curb appeal. Its softness is balanced by a distinct presence of color, ensuring it stands out gracefully without being overly bold. It’s an excellent choice for siding, front doors, or shutters. This versatile shade harmonizes beautifully with natural stone paths, crisp white trim, and lush green landscaping, fitting seamlessly into both classic, traditional, and more contemporary home architectural styles.

How Lighting Affects Coastal Plain’s Appearance

The direction and quality of natural light dramatically influence how any paint color, including Coastal Plain, manifests in a room. The same shade can subtly shift its tones depending on the time of day and the room’s orientation.

North-facing rooms: These spaces receive cooler, more indirect light. Consequently, Coastal Plain may appear slightly more muted with a stronger gray-green presence, enhancing its sophisticated depth.
South-facing rooms: Bathed in bright, warm sunlight throughout the day, these rooms can soften Coastal Plain, bringing out its warmer, earthy, and slightly yellow undertones, making it feel more inviting.
East-facing rooms: Morning light, often clear and bright, beautifully enhances Coastal Plain’s fresh, cleaner green side. It can feel exceptionally soft, crisp, and airy during the early hours.
West-facing rooms: As the day progresses into evening, the golden hues of late afternoon and sunset may highlight more of Coastal Plain’s inherent warmth, potentially revealing subtle olive or beige tones within the color.

Given these daily light transformations, it is absolutely essential to test a paint sample on multiple walls within your space. Observe how it behaves in the morning, at noon, and in the evening. This diligent sampling process will provide you with an accurate understanding of how Coastal Plain truly performs under your specific lighting conditions.

Coastal Plain vs. Other Popular Sherwin‑Williams Greens

Sherwin-Williams offers an impressive array of soft green paint colors, and it’s quite common to feel indecisive when faced with so many beautiful options. To help you navigate this choice, let’s explore how Coastal Plain compares to some of the brand’s most frequently discussed and beloved green shades.

Coastal Plain vs. Sea Salt (SW 6204)

Sea Salt (SW 6204, #CBD2C0) holds its reputation as one of Sherwin-Williams’ most perennially popular green-grays. However, it leans significantly cooler and contains noticeably more gray and blue undertones than Coastal Plain. Its higher LRV of 63 indicates it is a much lighter color.

Sea Salt often presents as an ethereal soft gray-blue, especially in low light conditions or north-facing rooms.
In contrast, Coastal Plain consistently retains its greener identity and warmer character, particularly evident under natural light, offering a more saturated yet still muted green.

If your design goal is a truly “barely-there” spa-like green, leaning heavily towards gray and blue, Sea Salt might be your ideal pick. However, if you’re seeking a truer, more discernable green that still maintains a calm, sophisticated softness and earthy warmth, Coastal Plain is undoubtedly a superior choice.

Coastal Plain vs. Comfort Gray (SW 6205)

Comfort Gray (SW 6205, #BDC3B6) is another prominent green-gray, somewhat more saturated than Sea Salt, yet still cooler in tone than Coastal Plain. While sharing a similar color family lineage with Sea Salt, Comfort Gray possesses more pronounced blue undertones and has an LRV of 54, making it lighter than Coastal Plain.

Comfort Gray frequently leans towards a distinct bluish cast, a characteristic that is amplified in cooler lighting environments.
Coastal Plain, on the other hand, steadfastly holds onto its inherent green warmth, projecting a more natural, organic, and earthy ambiance.

If your vision involves a coastal or spa-inspired aesthetic with a noticeable bluish undertone, Comfort Gray would likely be a more fitting option. Conversely, if your preference is for a softer, more grounded, and distinctly green hue, Coastal Plain will deliver a wonderfully relaxed and harmonious feel.

Coastal Plain vs. Evergreen Fog (SW 9130)

Evergreen Fog (SW 9130, #CBD0C2), celebrated as Sherwin-Williams’ 2022 Color of the Year, is a significantly deeper, moodier green characterized by more pronounced gray undertones and a lower LRV of 30.

Evergreen Fog unmistakably reads as a sophisticated, muted sage with a distinctly smoky and sophisticated aura, offering considerable depth.
In contrast, Coastal Plain is notably lighter and feels inherently more refreshing, casual, and breezy, lacking the intensity of Evergreen Fog.

Opt for Evergreen Fog if your design objective is to introduce profound depth, drama, and a touch of organic moodiness into your space. Choose Coastal Plain if your preference leans towards a breezier, lighter green that still injects ample personality and warmth, but with a more understated presence.

Undertone and LRV Comparison Table

For a quick reference, here’s how these popular green shades stack up against each other:

Paint Color	Undertones	LRV	Warm or Cool
Coastal Plain (SW 6192)	Yellow-gray green	37.00	Warm
Sea Salt (SW 6204)	Blue-gray green	63.00	Cool
Comfort Gray (SW 6205)	Blue-gray	54.00	Cool
Evergreen Fog (SW 9130)	Gray-green	30.00	Cool

While each of these Sherwin-Williams greens is adored for its individual charm and unique qualities, their appearance will invariably differ based on the specific lighting conditions within your room. Always make it a priority to sample them side by side in your own space to accurately discern which one harmonizes most perfectly with your home’s unique environment.

Best Color Pairings for Sherwin-Williams Coastal Plain

Sherwin-Williams Coastal Plain is a delightfully soft, earthy green that maintains a fresh feel without ever becoming overwhelming. It performs beautifully across various rooms in the home, but its true potential is unlocked when thoughtfully paired with the right trim, accent colors, and finishes. Here, I’ll share my preferred strategies for constructing a cohesive, relaxed, and utterly inviting palette centered around this versatile shade.

Trim and Ceiling Color Suggestions

The correct white trim is essential for pairing with Coastal Plain; it helps to define the architectural elements of your space and prevents the green from appearing muted or indistinct. These particular white paints offer exceptional complementary qualities:

Pure White (SW 7005, #F8F8F6): This is a beautifully soft, clean white that avoids feeling too stark or clinical. It offers a gentle contrast that perfectly complements Coastal Plain without competing for visual attention, creating a harmonious and balanced look.
Alabaster (SW 7008, #EDEAE0): A truly warm, creamy white that introduces just the right amount of soft contrast. Alabaster helps maintain an overall cozy and inviting feel, especially beneficial in spaces where you want to enhance warmth.
Extra White (SW 7006, #F4F4F4): For those desiring a crisper, more contemporary contrast, this cool-toned, bright white is an excellent choice for trim or ceilings. It provides a sharp, clean edge that highlights the muted green beautifully.

If you plan to paint your ceiling to match your trim, it’s best to stick with one of these suggested whites, applied in a flat or matte finish. This approach ensures the light in the room remains balanced, soft, and avoids any unwanted glare, contributing to the overall serene atmosphere.

Accent Wall and Furniture Colors that Harmonize

Coastal Plain offers remarkable flexibility in your decor choices. You can either lean into a beautifully calm, natural palette or strategically introduce contrasting colors for a touch more personality and visual intrigue.

For a soft, layered, and deeply serene look, consider pairing Coastal Plain with an array of warm whites, gentle tans, delicate clay pinks, or subtle dusty lavenders. These complementary colors thoughtfully add warmth and dimensional richness, proving particularly effective in bedrooms or living areas where an atmosphere of grounding and tranquility is paramount.
If you’re inclined to be bolder and inject more vibrancy, experiment with rich navy blue, sophisticated charcoal gray, timeless aged bronze, or even an earthy deep terracotta. These stronger shades provide a captivating pop against the sage-like backdrop of Coastal Plain, imbuing your space with a more modern, eclectic, or thoughtfully collected aesthetic.

When selecting furniture, pieces crafted from light oak, woven rattan, off-white, or oatmeal-toned upholstery will maintain a wonderfully breezy and light feel. However, don’t shy away from incorporating a vintage wood dresser, a striking navy accent chair, or even a piece of weathered leather furniture. These additions can create a compelling sense of balance and visual interest, anchoring the room.

Hardware and Flooring Compatibility

I’ve observed that Coastal Plain exhibits excellent compatibility with a wide array of finishes. However, selecting the right flooring and hardware can significantly elevate its natural beauty and ensure a cohesive design throughout your home.

For hardware, brushed brass introduces a lovely warmth that exquisitely complements the earthy green tones of Coastal Plain. If your style leans towards something crisper and more contemporary, polished nickel or chrome offers a clean, refined finish. For those who appreciate bold contrast, matte black hardware will make the green truly pop, adding a modern and edgy dimension to your spaces.
When making choices for flooring, light options such as white oak or light maple keep the room feeling fresh, open, and airy. Medium-toned woods like hickory or walnut introduce a grounding warmth and balance to the space. For tile or stone selections, opting for warm grays or soft greiges will beautifully echo Coastal Plain’s undertones, resulting in a seamlessly integrated and cohesive look.

Regardless of your final selections, the golden rule remains: always test all chosen elements together in your space. Coastal Plain is a subtle and nuanced color, and it often reacts to varying light, textures, and adjacent colors in surprisingly delightful ways.

Paint Finish Recommendations for Sherwin-Williams Coastal Plain

From experience, the paint finish you choose is far more than just a matter of durability; it significantly impacts how Coastal Plain appears and feels within your space. Each finish possesses unique light-reflecting properties that can subtly, yet effectively, alter the perceived depth and tone of the color.

Matte Finish: This finish is an excellent choice for low-traffic areas such as ceilings, formal dining rooms, or guest bedrooms. Matte paint is superb at concealing minor wall imperfections and bestows Coastal Plain with a soft, velvety, and deeply sophisticated appearance. In this finish, the green tends to appear more muted and absorbed, particularly in shaded corners or areas with lower light levels, enhancing its tranquil qualities.
Eggshell Finish: A highly versatile option, eggshell is ideal for moderate-traffic areas like living rooms, hallways, and home offices. It features a subtle, gentle sheen that reflects light without drawing undue attention to the wall texture. This finish allows Coastal Plain to maintain its calm, inviting presence while adding just a hint of understated vibrancy and depth.
Satin Finish: Renowned for its durability and ease of cleaning, satin is the perfect finish for high-use or moisture-prone areas such such as kitchens, bathrooms, and laundry rooms. Its noticeable, subtle shine can beautifully highlight Coastal Plain’s yellow or gray undertones, especially under brighter artificial or natural lighting, making the color feel more dynamic and lively.

If you’re deliberating between finishes, always perform a test swatch in various sections of your room. The interplay of lighting and existing wall texture can alter perceptions more than you might anticipate, making the sampling process an invaluable step.

Sampling and Buying Options for Sherwin-Williams Coastal Plain

Before committing to purchasing a full gallon of Sherwin-Williams Coastal Plain, it is an essential and wise step to thoroughly test the color in your actual living space. Factors such as room size, the direction of natural light, and even nearby furniture and decor colors can significantly influence how the paint looks once it is applied to your walls.

Where to Get Peel-and-Stick Samples

The most convenient and mess-free method for trying out Coastal Plain without the hassle of traditional paint cans is by utilizing peel-and-stick samples. These offer a realistic representation of the color on your walls.

Samplize offers high-quality, adhesive swatches featuring real Sherwin-Williams paint. These samples are designed to be easily removable, reusable, and will not cause any damage to your existing wall surfaces, providing a true-to-color preview.
Alternatively, your local hardware stores might carry Coastal Plain in smaller sample pots or as physical color chips for quick visual reference.
Sherwin-Williams stores typically provide complimentary painted sample cards and often sell convenient 8-oz. tester jars, perfect for brushing actual paint onto a section of your walls.

When sampling, affix these swatches to multiple walls within your chosen room and diligently observe them throughout the entire day. This practice will allow you to see precisely how Coastal Plain’s subtle undertones react and shift under varying light conditions, ensuring confidence in your final selection.

Where to Purchase Sherwin-Williams Coastal Plain Paint

Acquiring Sherwin-Williams Coastal Plain paint is straightforward, with both online and in-store options available to suit your convenience.

You can easily place direct orders through Sherwin-Williams.com, with options for convenient in-store pickup or direct home delivery.
Authorized Sherwin-Williams retailers are reliable sources, frequently stocking Coastal Plain in various finishes and container sizes.
Many large-scale hardware stores also have the capability to accurately tint paint using official Sherwin-Williams formulas, ensuring color consistency.
Furthermore, some stores may offer convenient services like curbside pickup or home delivery. It’s always a good practice to verify their specific availability and options in advance.

Paint Equivalents in Other Brands

Should you find yourself without convenient access to a Sherwin-Williams store or if you’re aiming to match Coastal Plain’s aesthetic with another paint brand, I’ve identified a few similar alternatives. It’s important to remember that each paint brand formulates its colors using a unique base and recipe, which means that undertones and overall finish might exhibit slight variations from the original.

Benjamin Moore: For rich, earthy green tones that lean soft and muted, consider trying Saybrook Sage (HC-114, #B9B89A) or Soft Fern (2144-40, #C7C8A3). Both offer a comparable tranquil vibe.
Behr: Explore Nature’s Gift (MQ6-45, #A7B6A0) or Pale Cucumber (PPU9-17, #D6D5BC) for gentle, sage-like greens that evoke a similarly calm and natural presence.

While these suggested shades can certainly get you in the general vicinity of Coastal Plain, it is always highly advisable to sample them side by side in your space. Even minor differences in paint base or sheen can subtly shift how the color is perceived once it’s applied to your wall, making comprehensive sampling paramount for achieving your desired outcome.
