Poseidon
What Poseidon Actually Looks Like
Poseidon is a saturated, medium-depth teal that sits right at the intersection of blue and green. It reads bright and clean in most light, closer to a true turquoise than a muted spa tone. In strong natural light it leans more green. In low light or north-facing rooms it pulls toward a deeper, cooler blue-green. It is not a whisper color. It makes a statement the moment it goes on the wall.
Poseidon Undertones
The dominant read is blue-green with a cool, slightly aquatic quality. There is no gray or brown softening this one. It is a clean, high-chroma teal, which means warm-toned surfaces nearby, like honey wood floors or brass hardware, will pop against it, while cool whites and silvers will feel cohesive.
Where Poseidon Works Best
Poseidon works best where you want the color to be the point. An accent wall, a powder room, a home office, a mudroom, or a kitchen island are all natural fits. It is also a bold exterior choice on front doors, shutters, or a coastal-style home body where the surrounding landscape includes sand, driftwood tones, or deep greens. In a large open room painted on all four walls it will dominate, so consider your furniture and floor tones carefully before committing.
Where to put Poseidon
A small, windowless powder room is one of the best places to commit to Poseidon. With no natural light to complicate things and only a small square footage to cover, you can lean into the full saturation. Pair it with a warm white trim and brass or unlacquered fixtures for contrast that feels intentional.
On cabinetry, Poseidon reads clean and graphic. It works especially well against white or off-white perimeter cabinets and a light stone countertop. In a semi-gloss or satin finish the color gains depth and becomes easier to wipe clean, which matters in a kitchen.
In a home office with decent east or west light, Poseidon provides real visual energy without feeling chaotic. It reads more green-teal in morning light and shifts slightly cooler in the afternoon. Keep the rest of the room neutral so the walls do the work.
On an exterior with white trim and natural wood accents, Poseidon earns its place. It suits cedar shingles, whitewashed siding as a trim companion, and landscapes with a lot of natural green. In direct sun it can read quite bright, so test a large swatch on the actual facade before committing.
A single accent wall in Poseidon can anchor a living room or bedroom without overwhelming the space. It works best on the wall behind a sofa or bed rather than a fireplace wall, where art and objects tend to compete. Keep the remaining walls a warm white or light neutral.
What to Pair With Poseidon
No Benjamin Moore coordinating colors are paired in our database for Poseidon 664, but the color gives you strong direction on its own. It plays well with warm whites, natural wood, aged brass, and deep navy or charcoal. Crisp off-whites keep it from feeling heavy, and natural linen or rattan textures balance its intensity.

Colors that clash with Poseidon
If adjacent rooms are painted in cool blue-grays, Poseidon can create a jarring color collision in open floor plans. The hues compete rather than flow.
A bright bluish white on trim will flatten Poseidon and make the combination feel cold rather than crisp.
Because Poseidon has no warm or pink undertone, purple accessories tend to look discordant rather than complementary.
Common questions
Poseidon's Benjamin Moore color code is 664. The LRV is 31.43, placing it in the medium-depth range, which means it reads as a true mid-tone color rather than a light or dark. Hex and RGB values render in the color swatch above.
It depends on how you want the room to feel. In north light, Poseidon will pull toward a deeper, cooler blue-green and lose some of its bright turquoise pop. That can actually be a beautiful effect in a smaller room like a powder room or reading nook, but in a larger north-facing living space it may feel colder than you expect. Test a large swatch and live with it through a full day before deciding.
For walls, an eggshell finish gives you a subtle sheen that lets the color breathe without the reflectivity of a satin. For trim, go semi-gloss regardless of which white you choose. On cabinetry, satin or semi-gloss both work and hold up better to cleaning.
Yes, and it is one of the strongest uses of the color. A front door in Poseidon against white or off-white siding and natural wood reads confident and welcoming. In direct sun it will look brighter and more green-leaning, so if you want the deeper teal quality to come through, an east or north-facing door will serve you better.
Warm wood tones, think honey oak, walnut, or teak, pair naturally with Poseidon because the warmth of the wood anchors the cool intensity of the teal. Cooler or gray-washed wood can make the combination feel flat. If your floors are a cooler gray-brown, bring in warmer accents through textiles and hardware to bridge the gap.
