Deep Sea Green
What Deep Sea Green Actually Looks Like
On the wall, Deep Sea Green reads very dark, closer to charcoal or near-black than to any recognizable teal. In most interior lighting conditions that cool blue-green quality stays quietly in the background. Step into direct daylight or flip on a warm-white bulb and the teal emerges clearly, giving the color a dual personality depending on when and where you look at it.
Deep Sea Green Undertones
The undertone is a cool blue-green, distinctly teal in character. It does not surface under flat or dim light, which is why the color can surprise you on the wall after you approved a fan deck chip in bright sunlight. Warm incandescent or LED bulbs in the 2700K range coax the teal out more than cool daylight fluorescents do. Adjacent white trim, light wood floors, and pale stone surfaces all act like mirrors and can pick up and reflect that teal cast back into the room.
Where Deep Sea Green Works Best
This color earns its place in rooms that are meant to feel enveloping and intimate. Low natural light is not a problem you fix with this color, it is a feature you lean into. Powder rooms, home bars, moody home offices, and primary bedroom accent walls are all natural fits. It works well on cabinetry, kitchen islands, and bathroom vanities where a dark saturated finish reads as intentional. Front doors and exterior trim are strong applications, especially on homes with light siding where the contrast does the work. Avoid it in rooms where you need to feel energized or where north-facing light is your only source, unless you want something that reads essentially black all day.
Where to put Deep Sea Green
A small powder room is the ideal first use for a color this dark. Four walls in Deep Sea Green with white trim and a warm vanity light will feel intentional and dramatic without overwhelming a space you only spend a few minutes in at a time.
On lower cabinets or an island, Deep Sea Green gives you the moody contrast of a near-black finish with the payoff of a teal reveal when sunlight hits it during the day. Pair with unlacquered brass hardware and a light countertop to keep the palette from closing in.
Exterior light is where this color performs best. Direct sun brings out the full blue-green, and on a shaded porch it holds a sophisticated near-black that reads as deliberate and confident. Use a satin or semi-gloss finish to maximize that color shift.
If you want a room that signals focus and containment, this color delivers it. Keep one wall lighter or use open shelving to break up the depth, and rely on warm task lighting to bring the teal character into the room during evening work hours.
A single wall behind the bed in Deep Sea Green creates a backdrop that feels grounded without requiring you to commit all four walls to a very dark color. Natural linen bedding and warm wood tones balance the coolness of the undertone.
What to Pair With Deep Sea Green
No coordinating colors are listed in our database for Deep Sea Green 735. Build your palette around it by treating the color as your anchor and pulling trims, textiles, and accents from what is already in the room. Warm brass or aged bronze hardware pulls the teal out. Natural oak or walnut floors ground it without fighting it. Crisp white trim sharpens the contrast and keeps it from feeling heavy.

Colors that clash with Deep Sea Green
When you pair Deep Sea Green with a cool gray trim, both colors pull in the same blue direction and the contrast you need to define the room disappears. The walls can feel dingy rather than dramatic.
Brushed nickel and cool chrome can make the blue-green undertone feel cold and flat in low light, pushing the whole room toward feeling washed out and institutional.
White oak with a gray or ashy finish, or pale gray tile, will amplify the cool undertone and make a dark room feel heavier and harder to warm up.
Common questions
The LRV is 8.9, which places it near the very dark end of the scale. For reference, true black is 0 and pure white is 100. At this level, the color will absorb most of the light in a room rather than reflect it, which is why it feels enveloping and why testing it in your specific room and lighting is essential before painting a full wall.
In most everyday interior lighting it reads close to near-black with only a hint of color depth. The teal character becomes visible in direct natural daylight or under warm incandescent and warm LED bulbs. If your room gets direct sun at any point during the day, you will see the blue-green. In a north-facing room with no direct sun, expect it to read very dark with minimal color identity.
For walls, eggshell gives you just enough sheen to bring out the depth without making imperfections obvious. For cabinetry and doors, satin or semi-gloss adds durability and amplifies that teal-to-near-black shift as light moves across the surface during the day. Flat finish tends to flatten the color and push it toward a more uniform near-black, so only use it if that is the effect you want.
Paint a large sample, at least twelve by twelve inches, on the actual wall you plan to paint. Live with it for two to three days and observe it in morning light, afternoon light, and under your artificial lighting at night. Also hold it next to your trim color and your floor material, since both will reflect the teal undertone back into the room and affect how you read the overall palette.
Yes, it is available in both interior and exterior Benjamin Moore formulations, which makes it a practical choice for projects like front doors or exterior trim where you want to carry the color through from inside to outside.
