Bone Black
What Bone Black Actually Looks Like
Bone Black lands in that interesting middle ground where a color is neither light nor dark. From the RGB values you can see it is a balanced, slightly warm gray, close to the midpoint of the value scale. It reads as a calm, composed neutral with a muted, almost dusty quality. It does not shout. In bright light it can lift toward a soft greige. In dimmer rooms it settles into a more convincing gray with just a whisper of warmth. The name is historically grounded: bone black is an actual pigment made from charred bone, and the color references that tradition rather than delivering a true near-black.
Bone Black Undertones
The RGB values show red and green channels nearly identical at 185 and 184, with blue a touch lower at 174. That gap is small but meaningful. It pulls the color faintly warm, nudging it away from a cool blue-gray and toward a gray with a slight organic, earthy quality. Do not expect a greige with obvious beige; the warmth is subtle. In cool north-facing light the warmth recedes and the color reads closer to a straightforward medium gray.
Where Bone Black Works Best
Because it sits right at the midpoint of the value scale, Bone Black is unusually flexible for trim, walls, or exterior applications. Benjamin Moore lists it for both interior and exterior use. On exterior woodwork it brings a historically appropriate, understated presence. On interior walls it works best in rooms that get decent natural light, since in a very dim room a mid-value warm gray can feel flat. It suits spaces where you want substance without committing to a true dark accent.
Where to put Bone Black
Bone Black was developed as part of the Colonial Williamsburg collection, and exterior use is where its historically grounded, slightly warm gray character reads most authentically. It works as a body color or trim color on traditional architecture and pairs naturally with off-whites and deeper charcoals from the same period palette.
At LRV 47.47, this color absorbs enough light to create a settled, focused atmosphere in a study without making the room feel cave-like. Use it on all four walls in a room with decent windows and keep ceiling and trim in a warm white.
A mid-value warm gray works well in a dining room because candlelight and warm bulbs will bring out the subtle warmth in the color. The color holds its composure without competing with table settings or art.
What to Pair With Bone Black
No coordinating colors are specified in the Benjamin Moore Colonial Williamsburg program listing for this color, so pairing recommendations below are based on general color principle and the character of the color itself.
Colors that clash with Bone Black
The faint warmth in Bone Black will conflict with strongly cool adjacent colors, making both colors look slightly off rather than intentionally contrasted.
A stark cool white paired with a mid-value warm gray can make the gray look dingy by comparison, especially in photographs or in rooms with mixed light sources.
Common questions
The Benjamin Moore code is CW-715. The precise LRV is 47.47, which places it almost exactly in the middle of the value scale from white to black. Hex and RGB values are shown in the color spec block on this page.
Yes. Benjamin Moore lists Bone Black as available in both interior and exterior formulas, which makes sense for a Colonial Williamsburg color intended to be historically accurate on period buildings.
Yes, and this matters at mid-value. In a flat or matte finish the color looks softer and the warmth is more apparent. In an eggshell or satin the slight sheen increases the apparent depth and the color can read a touch darker and more gray. On exterior woodwork in a satin or semi-gloss it will look noticeably richer than the same color in flat.
Despite the name, it is not a dark color. It is a true mid-tone. In a well-lit room it reads as a medium warm gray with presence. It will not create the dramatic moody effect you get from a deep charcoal or near-black. If you want something darker, you need to move to a color with a lower LRV.
