Sea Star
What Sea Star Actually Looks Like
Sea Star reads as a muted teal gray, sitting right at the intersection of blue and green without committing fully to either. It is not a bright color. The saturation is restrained, giving it a weathered, coastal quality that feels calm rather than bold. In strong natural light it opens up and leans more distinctly blue-green. In dim or artificial light it can settle into a darker, more neutral gray.
Sea Star Undertones
The color carries both blue and green undertones in roughly equal measure, held together by a gray base that keeps things from reading too saturated. That gray base is what makes it versatile. It prevents the color from looking tropical or cartoonish and keeps it grounded on a wall.
Where Sea Star Works Best
Sea Star suits rooms where you want a cool, settled atmosphere without going fully gray or fully blue. Bedrooms, bathrooms, and hallways are natural fits. It also works in living spaces that get good daylight, where the blue-green character has room to breathe. Avoid very dark rooms with no natural light, where it can turn flat and colorless.
Where to put Sea Star
Sea Star brings a genuinely restful quality to a bedroom. The cool blue-green hue reads quietly in morning light and settles to something almost smoky in the evening. Pair it with warm wood furniture and linen bedding to keep the room from feeling cold.
In a bathroom with good light, Sea Star earns its name. The watery blue-green feels intentional next to white tile and chrome or brushed nickel fixtures. In a windowless bathroom, test a large sample first because it can read noticeably darker and grayer without daylight.
A hallway in Sea Star creates a sense of continuity and calm between rooms. Because it leans gray in lower light, it transitions well alongside warmer rooms without clashing. Keep trim bright white to sharpen the edges and prevent the whole space from feeling murky.
Sea Star works in a living room that gets steady natural light. It gives the space a composed, grounded character without the starkness of a true gray. Warm up the furniture palette with tans, rusts, or natural fibers so the room does not read too cool or clinical.

Colors that clash with Sea Star
Sea Star is a cool color. Placing it directly adjacent to rooms painted in warm yellows or oranges creates a jarring temperature contrast that makes both colors look off.
Trim or built-ins with pink or lavender undertones will pull against Sea Star's blue-green base and make the wall color look muddier than it is.
At an LRV just under 33, Sea Star needs some light to show its color. In a basement or north-facing room with no windows, it can lose its blue-green character entirely and read as a dull medium gray.
Common questions
Sea Star's Benjamin Moore code is 2123-30, its hex is #889E9E, and its precise LRV is 32.99, placing it in the medium-dark range where good lighting makes a real difference.
It depends on your light. In warm afternoon sun it tends to read more green. In cooler north or morning light it pulls bluer. The gray base keeps it from going strongly in either direction most of the time.
Eggshell is the most practical choice for walls. It gives just enough sheen to bring out the color without highlighting imperfections. Use matte if you want the most subdued, flat read, or satin in bathrooms and kitchens where washability matters.
