Copper Mine
What Copper Mine Actually Looks Like
Copper Mine is a dark, saturated terracotta with the warmth of aged copper and fired clay. It reads as a deep red-brown in most light, somewhere between a brick red and a dark rust. It is not a true red and not a true brown. It sits in that specific territory where warm orange-red meets dark earth, and it carries real depth because of its low reflectance. In a dim room it can feel almost chocolatey. In strong direct sun it brightens toward a burnished copper tone.
Copper Mine Undertones
The dominant pull is warm orange-red, the signature of terracotta. There is enough brown in the mix to keep it grounded rather than fiery. You will not see significant pink or purple movement. In cooler or north-facing light the brown component strengthens and the color reads darker and more muted. In warm incandescent or afternoon light the orange-red comes forward and the color feels more energized.
Where Copper Mine Works Best
Because the LRV is very low, Copper Mine absorbs a lot of light. That makes it well suited to accent walls, powder rooms, dining rooms, and intimate spaces where you want the color to do real work. It is a committed choice for a full room. If you use it on four walls in a small space, commit to warm lighting so the color stays lively rather than closing in. It works beautifully on exterior doors and shutters, where the deep copper tone reads as distinctive without being garish. On large open-plan walls it can feel heavy unless the ceiling and trim stay light.
Where to put Copper Mine
A dining room is one of the strongest use cases for Copper Mine. Low LRV colors create intimacy around a table, and candlelight or warm pendant lighting will pull the copper and orange-red tones forward beautifully. Keep the ceiling a warm off-white to prevent the space from feeling like a cave.
Small square footage lets you commit fully to a bold, dark color without it feeling oppressive. In a powder room, Copper Mine becomes a statement. Brass or unlacquered bronze fixtures reinforce the warm metal reference in the name.
On a front door or shutters against a cream, sand, or warm gray body, Copper Mine reads as confident and grounded. It weathers the shift between overcast and sunny days better than brighter reds because the brown base keeps it from looking harsh in flat light.
If you want a room that feels focused and cocooning, Copper Mine on three or four walls with warm wood shelving and leather or linen furniture does the job. Plan your lighting carefully since the low reflectance means you will need adequate warm artificial light to work comfortably.

Colors that clash with Copper Mine
Copper Mine's warm orange-red undertone will fight with cool grays or blue-grays in an adjacent or open-plan space. The contrast is not complementary, it just looks unresolved.
Stark, bright white trim next to Copper Mine can make the wall color look muddy or overly dark by contrast. The cool brightness of a true white fights the warmth of the copper-red.
With an LRV just under 11, Copper Mine reflects very little light back into a space. In a room without natural light and with only overhead fluorescent or cool LED fixtures, the color can look flat and brownish rather than rich.
Common questions
The LRV is 10.92, which is quite low. Colors below about 15 absorb significantly more light than they reflect. In practical terms, Copper Mine will make a room feel smaller and more enclosed, which is an asset in intimate spaces but something to plan around in rooms that already lack natural light.
An eggshell finish is the most practical choice for most interior walls. It gives a slight sheen that helps the color stay lively without highlighting surface imperfections. Matte works in low-traffic rooms if you want maximum depth. Use a satin or semi-gloss on trim to create a clear separation.
Yes. Benjamin Moore offers it in both interior and exterior formulations, which is what makes it a solid candidate for front doors, shutters, and exterior accents as well as interior spaces.
Brass, unlacquered bronze, and aged copper are the most natural partners given the color's name and character. Matte black also works well if you want contrast. Avoid cool chrome or brushed nickel, which will fight the warm tone.
Sherwin-Williams Fired Brick (SW 6335) is in similar deep terracotta-red territory and is worth sampling side by side. Color behavior depends on your specific light and finish, so always test both in your actual space before committing.
