Color Family
Coastal Plain lives in the green family, but it’s not some punchy, in-your-face green. It leans toward sage, with a warm, mellow tone.
There’s a nature-inspired quality here—think soft moss or pale sage. It sets a relaxed mood, and honestly, it just feels easy to be around.
The muted vibe keeps it from overwhelming a room. You get personality and warmth without the color screaming for attention, so it fits in with both modern and traditional styles.

With an LRV of 37, Coastal Plain sits comfortably in the medium-light zone. It reflects enough light to keep things from feeling gloomy, but it’s not as bright as pale pastels or whites.

Real World Examples Of Coastal Plain by Sherwin Williams SW 6192 In Different Spaces
Coastal Plain fits into all kinds of spaces because it adapts to different light and purposes. It gives color and calm without making things complicated.
Bathrooms
Bathrooms get a spa-like vibe with Coastal Plain—never cold or sterile. The soft green works with white subway tile, marble, and either chrome or brushed nickel fixtures.
In small bathrooms, the mid-range LRV keeps things from feeling cramped. You can paint all the walls or just use it behind the vanity as an accent.
White trim and light wood accents (like bamboo mats or wood shelves) really pull the look together. The yellow undertones warm up under bathroom lights, so the space feels cozy, not clinical. White towels and a little greenery finish it off.
Bedrooms
Coastal Plain makes bedrooms feel restful but not boring. It works on all four walls or just behind the bed if you want a focal point.
Natural light brings out the softer green by day, and lamplight brings out the earthier tones at night. The color never stays exactly the same, which keeps things interesting. Pair it with white or cream bedding for a peaceful look.
Light oak or walnut furniture both look great. Modern, traditional, whatever—this color can handle it. Try linen curtains, a chunky knit throw, or a jute rug for extra coziness. I’d skip super-bright accents, though; they can disrupt the vibe.
Front Doors
A front door in Coastal Plain feels welcoming without being loud. It stands out just enough to catch the eye, but it’s not flashy.
This color looks especially good if your exterior is white, cream, gray, or light stone. It pairs well with brick or wood, and ties in with your landscaping, too.
Brass or bronze handles add warmth, while matte black hardware gives a more modern edge. Keep porch decor simple—maybe a natural doormat and a few potted plants.
Home Offices
Coastal Plain makes a home office feel productive but not sterile. The muted green keeps the space calm, but it’s not so bland you forget it’s there.
In north-facing rooms, it adds warmth where you need it most. Pair with white shelves, light wood desks, and neutral furniture.
The color won’t distract you or strain your eyes during long work sessions. Brass desk lamps or warm lighting can show off the softer side of the green. Stick with simple artwork and white pots for plants if you want to keep things uncluttered.
House Exteriors
Coastal Plain gives exterior walls a subtle, nature-inspired look that doesn’t go out of style. It isn’t bold, but it’s definitely more interesting than basic gray or beige.
You can use it for all your siding or just as an accent. It works well on craftsman homes, cottages, and ranches. The green looks great with stone walkways, wood shingles, and brick.
White trim and a contrasting door (white or dark) look sharp. The color holds up in all kinds of light and doesn’t fade too fast. Landscaping—especially evergreens or flowers—really pops against it. And hey, try it on shutters if you want everything to match up.
Kitchen Cabinets
Painting kitchen cabinets in Coastal Plain gives you a fresh, clean look that bridges modern and classic styles. It works well on lower cabinets with white uppers, or just go all-in and paint everything.
This green pairs nicely with white or light gray counters and both warm or cool backsplashes. Brass or gold hardware brings out the warmth, while chrome or nickel keeps things crisp. Natural wood open shelving or a butcher block island adds some texture.
It hides dirt better than white cabinets but still feels bright. Big kitchens with lots of light or small spaces that need personality—either way, it works. Simple white dishes and baskets make the look feel finished but not fussy.
Living Rooms
Living rooms get a boost of personality from Coastal Plain without losing their relaxed energy. The color makes a nice backdrop, letting your furniture and decor do their thing.
You can paint all the walls or just do an accent. The green fits modern sectionals or traditional sofas. White or cream trim keeps the space crisp.
South-facing rooms show off the warmer side, while north-facing ones lean more gray-green. Add texture with pillows, rugs, and curtains in cream, tan, or even soft terracotta. Wood tables, rattan chairs, or baskets add warmth without clashing.
Coastal Plain by Sherwin Williams SW 6192 Undertones
Coastal Plain has yellow and gray undertones that give it a soft, mossy vibe. These undertones keep the color from feeling too bright or artificial.
The gray keeps things balanced, so the green never gets too bold. It adds a muted, calm quality that makes the color easy to live with.
The yellow undertones add warmth and an earthy, organic feel. In the right light, those yellow notes show up more and make the paint feel inviting.
How the undertones shift:
- Natural daylight will highlight the green and yellow, making the color look lighter and fresher
- Incandescent lighting brings out the yellow-beige, giving the paint a richer, earthier look
- North-facing rooms make the gray undertones more obvious
Unlike greens with blue undertones, Coastal Plain stays warm. It never veers into teal or aqua, so it’s different from colors like Sea Salt or Comfort Gray that feel cooler.
The yellow and gray undertones make Coastal Plain flexible—it fits in both warm and cool rooms. Always test a sample on your wall first. Lighting and nearby colors can really change how it looks.
How Does Lighting Affect Coastal Plain by Sherwin Williams SW 6192?
Coastal Plain’s green-gray tones change with the light. The color can feel cooler or warmer depending on the time of day and your lighting choices.
Natural Lighting
Natural light brings out different sides of Coastal Plain. In north-facing rooms, it looks cooler and more gray-green because the light is softer and less warm. The blue-gray hints show up more.
South-facing rooms get lots of warm light, so Coastal Plain looks lighter and shows off its green side. The color feels fresh and balanced here.
East-facing rooms see the color at its crispest in the morning, then it gets more subdued and gray as the day goes on. West-facing rooms are the opposite—muted in the morning, but the color glows with golden light in the afternoon.
Artificial Lighting
Your choice of bulbs really changes how Coastal Plain looks at night. Warm white bulbs (2700K-3000K) pull out the yellow undertones and make the green feel cozy—great for bedrooms or living rooms.
Cool white or daylight bulbs (4000K-5000K) show off the gray and blue undertones, so the color feels crisper. That’s usually better for kitchens, bathrooms, or workspaces.
LEDs keep the color consistent, while old-school incandescent bulbs add warmth. Dimmer switches are handy if you want to tweak the mood and see the color shift a bit as the evening goes on.
Coastal Plain by Sherwin Williams SW 6192 LRV 37 (Light Reflectance Value)
Coastal Plain comes in with an LRV of 37, landing it right in the medium range. This number gives you a sense of how much light the color will bounce around your room and how it might actually look once it’s up on your walls.
What Is LRV?
LRV means Light Reflectance Value. Basically, it’s a measure of how much light a paint color reflects, running from 0 (pitch black) to 100 (pure white).
Zero means total light absorption, while 100 means total reflection. Most paint colors are somewhere in the middle, just like real life.
Higher LRVs reflect more light, making rooms feel bigger and airier. Lower LRVs soak up more light, giving spaces a cozier, more intimate vibe.
If you know the LRV, you can make smarter choices for your lighting and room size. It’s honestly a handy number to have in your back pocket.
Coastal Plain by Sherwin Williams SW 6192 LRV Range
Coastal Plain sits right in the middle: not too light, not too dark. With an LRV of 37, it absorbs a fair bit of light, but doesn’t drag a room down.
It won’t bounce light around like a bright white, but it doesn’t make a space feel closed in or heavy either. This shade fits best in rooms with good natural light, where it can show off its green notes.
In a north-facing or dim room, you might notice it going a little more muted and gray-green. In a sunny, south-facing spot, it feels fresher and leans into its green side.
Small room? The medium LRV keeps things cozy without making you feel boxed in. In a bigger space, it adds color without taking over the whole vibe.
