Tricorn Black: Undertones, Best Rooms & Pairings

Hold a fan deck of "blacks" up to a window and watch what happens: hardly any of them are actually black. They split into camps. Warm browns. Cool blues. Soft charcoals that quietly turn gray on a sunny wall. Sherwin-Williams Tricorn Black (SW 6258) is the rare exception. With a Light Reflectance Value of 3 and a digital hex of #2F2F30, it is the SW deck's true, undertone-free black, the one designers reach for indoors when they want a wall, a cabinet, or a built-in to read as uncompromising black and stay that way from morning light to lamplight.

This page covers Tricorn Black inside the home: on accent walls, cabinetry, trim, doors, and ceilings, plus how it behaves under real interior light and what to pair it with. Choosing it for siding, shutters, or a front door seen from the street is a different decision (sun load, fade, vinyl warranties), and we cover that separately in the Tricorn Black SW 6258 exterior guide. The two are complementary: this one owns the indoor story, that one owns the facade.

Tricorn Black SW 6258 at a glance

Here are the numbers that actually drive the decision. They come straight from the Sherwin-Williams digital color library and design swatch.

• SW code: 6258.
• LRV (Light Reflectance Value): 3. For context, a pure builder white sits near 90 and a soft "black" like Iron Ore is around 6. At LRV 3, Tricorn reflects almost no light, which is what makes it read as true black rather than charcoal.
• Hex approximation: #2F2F30. RGB roughly 47, 47, 48. Notice the three channels are nearly identical, that near-equal red, green, and blue is the mathematical signature of a neutral with no color bias.
• Undertone: none worth naming. No warm brown, no cool blue, no green-gray drift. This is the single reason it is specified so often indoors.
• Tint base: ultra-deep (extra-deep) base only. No light or medium base will ever reach LRV 3, so a "Tricorn Black" mixed into the wrong base will come out a flat dark gray.

For where Tricorn fits among neutrals and how the LRV scale works in general, the interior paint color families guide maps the full range from whites to true blacks. And if you are still narrowing your palette, the best interior paint colors for 2026 roundup shows where black accents land this year.

Does Tricorn Black really have no undertone?

Practically, yes, and that is unusual. Every other near-black you will compare it to leans somewhere, and that matters indoors, where one wall is lit by cool daylight and warm lamplight in the same hour.

A black with a warm base (think Iron Ore) picks up the brown and looks almost espresso under 2700K bulbs, while a cool-based black (Benjamin Moore Wrought Iron) can flash blue-charcoal under north light. Tricorn does neither. Because its red, green, and blue values are so close, there is no dominant channel for the room's light to amplify, so it stays black under warm powder-room sconces and in a north-facing study at noon alike.

The one caveat: at LRV 3 the wall has almost nothing to reflect, so what you mostly see is the sheen, not the hue. In flat or matte, Tricorn reads as a deep, light-absorbing void (dramatic and modern). In satin or semi-gloss it picks up window reflections and edges, which can make the same paint feel a half-shade lighter and far glossier.

Best rooms for Tricorn Black indoors

Black is a confidence color, not a fill color: the goal is rarely "paint the whole room" but to anchor a space or make one feature disappear into drama. Here is where Tricorn earns its keep, from most forgiving to boldest.

Home office and study (the safest big win)

A single Tricorn accent wall behind a desk reads as focused and editorial, and it makes brass hardware, walnut furniture, and framed art pop. Because an office is usually a smaller, lower-traffic room with at least one window, you get the drama of black without the cave feeling.

Powder room (small, windowless, high-impact)

A powder room is the designer's favorite place to be bold, because no one spends an hour in it. Tricorn on all four walls, often up onto the ceiling, turns a forgettable half-bath into the most memorable room in the house. Pair it with a white or marble vanity, a large mirror to bounce light, and warm metallic fixtures, and choose a satin or semi-gloss that wipes clean in a wet room.

Cabinetry, islands, and built-ins

Tricorn is a staple for a kitchen island base, a butler's pantry, lower cabinets under lighter uppers, and floor-to-ceiling library shelving, almost always in a satin or semi-gloss for a durable, furniture-grade finish. Against white countertops and warm wood floors, black lowers read as grounded and expensive, not heavy.

Interior doors and trim

Painting interior doors (or a window sash) Tricorn while keeping walls light is a high-style, low-commitment move. Black doors with black hardware against off-white walls is one of the most-saved looks of the last few years, and the natural entry point if you want black but cannot commit to a whole wall.

Ceilings and moody bedrooms (advanced)

A Tricorn ceiling in a den, library, or primary bedroom feels cocooning and luxurious. Whole-room black is the boldest option and works best in spaces you want intimate at night, not bright in the morning, with ample artificial light because the walls give almost none back.

Wherever you use it, budget realistically: deep tint bases need more coats and tinted primer, which nudges up paint and labor. The interior house painting cost guide breaks down why a saturated black room costs more than a standard off-white repaint.

Trim, wall, and decor pairings

Because Tricorn is neutral, it plays well with almost anything, but a few pairings are reliably flattering and worth specifying by name:

• Crispest contrast trim: Sherwin-Williams Pure White (SW 7005). A clean white that makes black doors and accent walls read sharp and architectural without going cold.
• Softer, warmer companion white: Sherwin-Williams Alabaster (SW 7008, LRV 82). For a black-and-warm-white scheme that feels cozier than stark. See how Alabaster itself shifts by room in our Alabaster north-facing undertones guide.
• Greige walls with black accents: pair Tricorn doors or built-ins with Repose Gray or Agreeable Gray walls for a layered neutral scheme that is warmer than black-and-white alone.
• Warm-beige envelope: a black island or pantry against Accessible Beige walls grounds an open kitchen beautifully.
• Color, not just neutrals: Tricorn flatters muted greens and blues. A black accent next to a soft sage like Sea Salt reads modern and calm rather than harsh.
• Metals and wood: brass and aged gold are the classic warm counterpoints, matte black hardware doubles down on the look, and warm oak or walnut floors keep a black room from feeling cold.

Tricorn Black vs other interior blacks

"Just pick a black" is a trap, because the near-blacks read very differently on a real wall. Here is how Tricorn stacks up against the blacks people most often cross-shop indoors:

LRV and undertone values per Sherwin-Williams, Benjamin Moore, and Behr published color data; undertone notes reflect designer consensus (The Spruce, designer references). Values are approximate and shift with finish and light.

So here is the call in one breath. Reach for Tricorn when you want true black with zero drift. Switch to Iron Ore when "black" feels too hard and a warm soft-black is closer to what you pictured. And go Benjamin Moore only if you already buy that brand. For a fuller head-to-head, see our Sherwin-Williams vs Benjamin Moore interior comparison. For the SW line as a whole, the Sherwin-Williams interior paint colors 2026 guide is the hub that ties these profiles together.

How to test Tricorn Black before you commit

Sampling a black is trickier than sampling a white. The differences between near-blacks are subtle, and bad lighting washes them out in seconds. Stick to four rules and the test holds up:

• Never judge from a fan-deck chip. A 1-inch chip surrounded by white paper looks lighter than a rolled wall. Use a 12-inch peel-and-stick sample or paint a large poster board.
• Test the finish you will actually use. The same Tricorn in flat versus satin looks like two different colors, so sample your chosen sheen, not whatever the store had.
• Look at it morning, midday, and night. Black shifts most between bright daylight and lamplight, so view the swatch around 9 a.m., 2 p.m., and again under your evening bulbs.
• Place it next to the trim and floor. Black always reads in contrast, so tape the swatch beside your real white trim and on a board near the floor.

The fastest no-paint option is digital: upload a real photo of your room into our interior paint visualizer and apply Tricorn Black (plus Iron Ore for the warm-black comparison) to one wall, judging it against your own trim and light first.
