Deep Sea
What Deep Sea Actually Looks Like
Deep Sea 623 reads as a saturated teal-green, sitting somewhere between a forest green and a true teal. It carries real depth, the kind that makes a room feel considered and grounded rather than loud. In strong natural light it opens up and shows its blue-green balance clearly. In low light or north-facing rooms it pulls darker and greener, reading almost like a deep jade.
Deep Sea Undertones
The color balances blue and green in roughly equal measure, with the green edge becoming more dominant in dim or artificial light. There is no meaningful yellow or gray pull here. What you get is a cool, watery depth that stays true across most conditions, though it can lean slightly more teal in warm incandescent light.
Where Deep Sea Works Best
Deep Sea works well on a single statement wall, on cabinetry, or as a full-room color in spaces where you want intimacy and atmosphere. It suits dining rooms, home offices, libraries, and powder rooms especially well. Because its LRV is low, it absorbs light rather than reflecting it, so smaller spaces feel intentionally cocooning rather than accidentally dark when you commit to it fully.
Where to put Deep Sea
Deep Sea on all four walls in a dining room creates exactly the kind of enclosure that makes evening meals feel more intentional. Pair it with warm candlelight and a wood table and the color comes alive in a way that flat daytime photos never capture.
A north or east-facing home office in Deep Sea feels focused and calm without being sterile. The color recedes visually, which keeps the room from feeling cluttered, and the green undertone is easier on the eyes during long screen sessions than a cooler blue would be.
Small square footage is no obstacle here. Going all-in with Deep Sea in a powder room, including ceiling, gives you a jewel-box effect that works precisely because the space is contained. Warm brass fixtures and a light mirror frame keep it from feeling heavy.
Deep Sea on lower cabinets paired with a warm white or off-white upper cabinet is a grounded, cohesive look. The color holds up well next to natural stone counters with warm veining, and it gives kitchens a sense of permanence that lighter greens rarely achieve.
What to Pair With Deep Sea
No formal coordinating colors are listed in our database for Deep Sea 623, but the color pairs naturally with warm off-whites and creamy trims to balance its cool depth. Natural wood tones, warm brass or aged brass hardware, and terracotta or rust accents all play well against it. A soft linen or warm sand on adjacent walls keeps the palette from feeling cold.

Colors that clash with Deep Sea
Pairing Deep Sea with a cool blue-gray on an adjacent wall flattens both colors. They compete without contrast, and the result reads as monotonous rather than cohesive.
Cool chrome fixtures pull the blue in Deep Sea forward aggressively, making the overall palette feel cold and clinical rather than rich.
A stark, cool bright white trim next to Deep Sea creates a harsh contrast that makes the color look heavier and more blue than it actually is.
Common questions
The precise LRV is 14.54, which puts it firmly in the dark range. That is not a problem if you use it with intention. Spaces with good artificial lighting, warm-toned fixtures, and light-reflective surfaces like mirrors or light wood floors handle it well. If your room has very little light of any kind, going full-room may feel oppressive, and a single accent wall or cabinetry application will be more livable.
Matte or eggshell finishes let the depth of the color read as intended and avoid any glare that would interrupt the moody quality. In kitchens or bathrooms where you need scrubability, a satin finish works well without dramatically changing the character of the color.
It depends on your light. In warm incandescent or candlelight it tends to read more green and even slightly olive at the edges. In cool daylight or north-facing light it pulls toward a truer teal and reads more blue. Both readings are intentional-looking, just different moods.
