Rosemary SW-6187 is one of those dark greens that looks like it belongs in a room with leather chairs and old books — earthy, warm, and seriously rich. I used it on a built-in bookcase and a powder room, and the pairing questions came up every time I posted a photo. Here’s what actually works with it.
What Is Rosemary SW-6187?
Rosemary is a deep, warm green from Sherwin-Williams with an LRV around 9. That’s dark — almost as dark as some of the popular blacks and navies. It reads as a rich olive green with earthy depth and real warmth. Not bright, not minty, not teal. Think dried herbs and aged leather.
It’s a bold choice that works best in controlled doses or in rooms where you want dramatic impact — accent walls, cabinets, built-ins, front doors, powder rooms. Full rooms of Rosemary need enough light to keep the green visible, or it’ll read as a very dark neutral. The color has been gaining traction with people who want something richer than the muted sage greens that have dominated lately.
What Undertones Does Rosemary Have?
Rosemary is a warm green through and through. The dominant undertone is yellow-green — olive, earthy, herbal. There’s nothing cool, blue, or gray about this color. It’s warm the same way a woolen blanket is warm.
In good light the olive quality is clear. You can see the yellow-green base and the warmth it carries. In dim rooms or at night, the yellow recedes and Rosemary can read as a very dark neutral — almost black-green. It never goes blue or teal. The warmth is baked in. If you want a dark green that feels organic and grounded, the olive undertone is a strength. If you want a cooler, more modern dark green, Rosemary will feel too earthy.
Rosemary vs. Pewter Green — Which Should You Pick?
Pewter Green SW 6208 is the other popular dark green from Sherwin-Williams, and they solve different problems. Both sit at a low LRV — Pewter Green is around 13 — but the undertone split is clear.
Pewter Green runs cooler and grayer with a blue-green quality. It feels more modern and more neutral. Rosemary is warmer and more olive — it feels more traditional and more earthy. I put both up on Paintuma side by side on a real wall photo, and the temperature difference was obvious. Pewter Green looked like a moody teal-gray. Rosemary looked like a rich herb garden at dusk. If your space has warm metals and warm wood, Rosemary fits. If you’re working with cooler finishes and a more contemporary vibe, Pewter Green adapts better.
How Does Rosemary SW-6187 Look in Different Lighting?
Bright south-facing light is where Rosemary really performs. Direct sun brings out the olive-green undertone and shows you all the richness and depth the color has. You can see the green, you can see the warmth, and the walls look alive. This is the best version.
North-facing rooms darken it further. Without direct light, Rosemary can read very close to black — the green disappears and you get a dark, warm neutral. That’s not necessarily bad for a powder room or an accent wall, but you lose what makes the color special. East-facing rooms catch good morning light. West-facing rooms warm up in the evening and the olive glows.
For bulbs, warm LEDs at 2700K to 3000K keep the green visible and the warmth feeling natural. Cool daylight bulbs fight the olive and make it look muddy.
Does Rosemary Work on Exteriors?
Surprisingly well. At LRV 9, you’d expect it to look almost black outside, and in heavy shade it does go very dark. But in direct sunlight, Rosemary opens up and shows its green. You get a rich, warm dark green in sun and a near-black in shade — and that combination actually looks great on a house.
Front doors are an obvious win. Rosemary on a front door against white or cream siding makes a strong statement without being loud. Full exterior siding works on smaller homes and cottages where the dark color creates intimacy. Shutters and garage doors are solid applications too. Same heat-absorption caution as any very dark paint — check your siding manufacturer’s LRV guidelines before doing the full body.
What Colors Go With Rosemary SW-6187?
For trim, Alabaster SW 7008 is a natural partner. The warm white echoes Rosemary’s warm olive base — no temperature conflict. Extra White SW 7006 works if you want a crisper, more defined contrast. Pure White SW 7005 sits between the two.
On walls surrounding a Rosemary accent or cabinet run, warm neutrals pair the most naturally. Accessible Beige SW 7036, Agreeable Gray SW 7029, or Alabaster on the surrounding walls all complement without competing. I slid Rosemary SW-6187 next to several coordinating options on Coloraw to compare, and the warm neutrals looked cohesive every time. For hardware, warm brass is the standout — it picks up the olive undertone and the pairing feels intentional. Matte black works for a more grounded look. Cool silver can clash with the warmth.
What Are the Closest Matches From Other Brands?
Benjamin Moore Tarrytown Green HC-134 is the closest widely cited match. It’s a dark green from the Historical Collection with a similar earthy depth. Tarrytown Green leans slightly more saturated and less olive — a touch more pure green where Rosemary has more yellow-olive character. Side by side you’d spot the difference, but they occupy the same space.
Benjamin Moore Essex Green HC-188 comes up too, but it’s darker and cooler — less warm, less olive. Not the same feel. For Behr, some of their dark greens land in a similar neighborhood, but I haven’t found one that nails Rosemary’s particular warm olive profile. Dark greens with specific undertones are tricky to match across brands. A painted swatch is your best bet for cross-brand matching.
Should You Sample Rosemary Before Buying?
With a color this dark and this warm, sampling is critical. Dark paints amplify surface imperfections and show every roller mark. You need to see how the sheen and the depth interact with your walls and your application technique, not just the color itself.
Paint a big swatch — bigger than a foot square — on two walls. Watch it in different light throughout the day. Pay attention to the difference between the sunny wall and the shaded wall. Dark colors shift more dramatically between lit and unlit surfaces than anything in the neutral range.
For a quick preview, paintcolorvisualizer.com lets you upload a photo of your room and test the color for free. It works for interior and exterior. It’s especially useful with darks because it shows you the visual weight at full scale before you buy gallons.
Bottom line: Rosemary SW-6187 is a warm, olive-toned dark green with real depth and character. Pair it with warm whites and brass, give it enough light to show its green, and it’ll anchor any space it touches.
