Benjamin Moore Sea Pearl OC-19: Cool-Gray Off-White

Benjamin Moore Sea Pearl (OC-19), spelled Seapearl on the maker's own site, is one of those off-whites that quietly does a lot of work without ever announcing itself. It is not a stark white, not a greige, and not a cream. Benjamin Moore sums it up in one line: "Cool gray undertones freshen up this shade of white." Homeowners search for it because a designer specified it, or because they swatched a wall of bright whites and Seapearl was the one that felt calm instead of clinical. The question that drives every search is the same: is it warm or cool, and what undertone is hiding in it. The answer depends on your light and your trim; here is how a color with these published numbers behaves on interior walls.

Quick orientation first. The Benjamin Moore Seapearl OC-19 color page gives an LRV of 76.43 and a screen value of #E7E4D9 (RGB 231, 228, 217). That places it in light off-white territory: high enough to keep a room bright and open, but well short of a bright white, so it reads as a finished wall color rather than a primer. The undertone is the interesting part: the maker calls it cool gray, while the screen value is close to neutral with only a faint warm base. That combination is why Seapearl reads as a soft, slightly grayed white rather than a cream. This profile is one stop in our wider Benjamin Moore interior paint colors guide, and it sits comfortably alongside the softer picks in our off-white paint colors guide.

Sea Pearl at a glance: the numbers that matter

Before opinions, here are the verifiable specs straight from the Benjamin Moore color library. These are the values you can take to a paint counter:

The takeaway from those numbers: Seapearl is a true off-white, not a white-white and not a greige in disguise. At LRV 76.43 it bounces a lot of light, so a small or low-light room still feels open, yet it stops short of the glare of a bright white in the high 80s. The undertone is the whole identity: a cool gray that keeps it fresh rather than creamy, sitting on a near-neutral base that stops it from looking icy. Understand that balance and Seapearl is one of the more livable off-whites in the collection.

Is Sea Pearl warm or cool? The undertone, decoded

Benjamin Moore's answer is cool: its description credits Seapearl with cool gray undertones. Earlier versions of this page called it warm, and that was wrong. Anyone bracing for a buttery cream will be surprised by how clean it stays; anyone expecting a stark blue-white will find it softer than that. Here is what is happening underneath the surface.

The published screen value tells the rest of the story: red, green and blue sit within fourteen points of each other (231, 228, 217), which is what a near-neutral pale off-white looks like, with blue slightly lowest. So the gray is the dominant impression, and the faint warm base keeps it from turning steely. In cool or indirect light the gray side steps forward and Seapearl reads quieter and a little grayer. In bright, warm light it softens and can look faintly warmer. This is why the same gallon can look crisp and fresh in a north bedroom and softer in a sunny kitchen: the light is pulling different threads of the same color.

Watch out for one quirk that trips up a lot of shoppers. Sea Pearl can look almost flat-white on a tiny fan-deck chip, which leads people to assume it is a plain bright white. On a full wall, especially next to a crisp white trim, the gray depth shows up clearly and the contrast surprises them. Always judge Sea Pearl as a rolled wall, never as a two-inch chip held in your hand.

Best rooms for Sea Pearl

Soft and forgiving, Seapearl is the off-white you reach for when you want a room to feel calm and finished rather than bright and busy. It is a whole-home candidate because it is light enough to keep rooms open while the gray keeps it from looking stark. Here is where it consistently earns its keep:

Living rooms and open-plan main floors

This is Sea Pearl's sweet spot. In a living room with decent light it reads as a soft, quiet backdrop that lets wood tones, brass, and natural fabrics carry the warmth without competing with them. Because it shifts gently with the light, an open-plan space painted entirely in Sea Pearl feels cohesive but never monotonous. If you want to see how it sits among other soft picks, our white living room paint ideas for 2026 is a useful map.

Bedrooms aiming for calm and restful

In a bedroom the soft gray reads soothing rather than stark, the kind of color that makes a room feel like a quiet place to land. It pairs well with linen, oatmeal, and pale wood, which add the warmth the wall itself does not, and it avoids the glare a bright white can bring under lamps at night. If a restful bedroom is your project, our guide to calming master bedroom paint colors shows how warm off-whites sit next to other quiet picks.

Kitchens and cabinetry

Seapearl works on cabinets that should read soft rather than stark. On uppers and islands it gives a not-quite-white look that sits well with warm metals and butcher block, while staying lighter and cleaner than a true cream. For more on coordinating it with backsplash and counters, see our white kitchen paint ideas for 2026.

Where to think twice

A small, dim, north-facing room with only cool LED light is where Seapearl can lose its charm. There the cool gray dominates and the wall can read flat and slightly dull. If that room needs warmth, lean into 2700K bulbs or pick a frankly warmer white such as Bone White instead. Seapearl gives its best in rooms with at least some natural light.

Trim, ceiling, and decor pairings

A soft off-white like Seapearl lives or dies on what sits next to it. Choose the trim well and it looks intentional and layered; choose it badly and the wall can look like it needs a second coat.

• Soft white trim (cleanest contrast): BM White Dove (OC-17, LRV 83.16) is the classic pairing. It sits about seven points above Seapearl and reads as a clean, soft white, giving a gentle step-up without a jarring line. This is the safe, cohesive pick for most homes, and its details live in our White Dove OC-17 review.
• Same color, different sheen (seamless look): running Seapearl on both walls and trim, eggshell on walls and satin on trim, gives a soft monochrome envelope that feels calm. Best for serene bedrooms and reading rooms.
• Use with care: a very bright trim white near LRV 90 makes a much stronger step (about fourteen points) and can make Seapearl walls look dingy by comparison. Sample it against the wall before committing.
• Ceilings: a soft white (often the trim color) keeps the room bright. Seapearl itself can go on the ceiling in a small space for a cocooning, no-line effect. If you want the opposite, a ceiling that lifts, Benjamin Moore Distant Gray OC-68 stays on the cool side (Benjamin Moore calls it a bright white with a hint of blue) and adds about twelve points of reflectance (LRV 88.14), so it brightens overhead without switching to a warm undertone.
• Floors and decor: warm oak, rattan, brass, linen, and unlacquered hardware bring the warmth that Seapearl leaves out, and keep a cool-gray off-white from feeling cold. Very cool gray flooring plus cool lighting can make the whole room read chilly; balance it with warm textiles.

For contrast and a bit of grounding, a soft black or deep olive on a door, an island, or built-ins reads tailored and modern against the pale walls. If you want to step down to a slightly deeper neutral as a sibling color (LRV 68.64, warm gray undertones), its closest greige relative is covered in our Benjamin Moore Pale Oak OC-20 review.

Sea Pearl vs the off-whites people confuse it with

Seapearl is often named as a twin of Bone White, and Benjamin Moore's pages say otherwise: Seapearl OC-19 (LRV 76.43) has "cool gray undertones", Bone White OC-143 (72.13) is "a gentle buff hue"; one is cool, the other warm. Our Bone White review puts the two side by side with White Sand and Baby Fawn.

Almost every Sea Pearl search ends in a side-by-side with another Benjamin Moore off-white. These are the ones that matter most indoors, and getting the difference straight saves you a wasted sample pot:

• vs BM Bone White (OC-143): the one people mix up most, often under the wrong number OC-15. Bone White (LRV 72.13) is "a gentle buff hue" in Benjamin Moore's words: four points deeper and clearly warmer. Seapearl is the lighter, cooler of the two. Choose Bone White when you want a warm, cream-leaning off-white; choose Seapearl when you want a white that stays fresh and slightly gray.
• vs BM Maritime White (OC-5): Maritime White (LRV 71.6) is "a sophisticated off-white with muted beige tones", about five points deeper than Seapearl and warmer. Pick Maritime White when you want a soft beige-leaning off-white; pick Seapearl when you want the lighter, cooler white.
• vs BM Pale Oak (OC-20): Pale Oak (LRV 68.64) is the next step down, a light greige with warm gray undertones rather than an off-white. It carries more gray and more visible color, so it reads as a pale neutral wall, while Seapearl still passes as a white at a glance.
• vs BM Cloud White (OC-130): the one to check when the room is short on daylight. Cloud White (LRV 85.05) sits about nine points higher and Benjamin Moore describes it as soft and balanced, so it gains reflectance without Seapearl's cool gray. That is what a dim north room lacks, and it is why Seapearl can go flat there while holding up well in a brighter space. Our Cloud White OC-130 review has the full profile.

Spelling note: sea pearl benjamin moore, BM Sea Pearl, and Benjamin Moore Sea Pearl OC-19 all point to this same off-white, which Benjamin Moore spells Seapearl and also lists under the classic number 961.

How to test Sea Pearl before you commit

A tiny fan-deck chip is the number-one reason people misjudge a soft off-white: it flattens Seapearl into a generic white and hides the gray that shows up at full scale. Two better methods:

• Paint a large swatch: roll a 12-by-12-inch sample (or a peel-and-stick sample) on two different walls and check it mid-morning, mid-afternoon, and at night under your normal bulbs. Watch specifically for how gray it goes in your coolest corner and how soft it goes in your sunniest spot; those two extremes tell you the whole story.
• Preview it digitally first: upload a real photo of your room and apply Seapearl, plus two warmer, slightly deeper alternatives such as Bone White and Maritime White, before you buy any samples, narrowing three contenders to the one worth painting. Pricing context for the full repaint is in our interior house painting cost guide for 2026.
