Seaside Blue
What Seaside Blue Actually Looks Like
Seaside Blue 2054-50 reads as a clear, medium-toned aqua. It sits comfortably between blue and green without committing fully to either, giving it that open-water quality that feels fresh without being loud. It is not a pale whisper of a color and not a deep saturated statement either. It lands in the middle, bright enough to energize a room but light enough to stay easy to live with.
Seaside Blue Undertones
The color carries green-leaning undertones that push it toward teal in certain lights. In warm afternoon sun it can feel more purely blue. In cooler north-facing or overcast light, the green pull becomes more noticeable and the color reads closer to aqua or soft teal. The undertone is relatively transparent, meaning what you see on the chip is close to what you get on the wall, though the green component will shift depending on what you place next to it.
Where Seaside Blue Works Best
Seaside Blue works well in rooms where you want an active, cheerful atmosphere without going dark. Bathrooms and laundry rooms are natural fits because the color echoes water and feels clean. It also holds up in kitchens, especially on an island or lower cabinets where you want color without overwhelming the space. On an exterior, it reads as a confident coastal choice for siding or shutters. Because its LRV sits near the midpoint, it provides enough depth to feel intentional on large surfaces.
Where to put Seaside Blue
A full bathroom in Seaside Blue feels like a clean refresh every time you walk in. Keep fixtures white and hardware brushed nickel or chrome to let the aqua do its work without competition.
Use it on a kitchen island or lower cabinets against white or light wood uppers. The color adds personality without making the space feel smaller, and it holds up under the warm task lighting most kitchens run.
On siding or shutters it reads as a classic coastal blue that works on cape-style houses or bungalows. Pair with crisp white trim to keep it grounded and avoid letting the green undertone drift toward anything yellow in your surroundings.
A hardworking utility space gets a real lift from this color. It makes a functional room feel intentional rather than forgotten, and you are not worried about it being too precious in a space that takes a beating.

Common questions
The LRV is 47.43, which puts it squarely in the middle range, neither light nor dark. A small room will read as colorful and active rather than airy. If you want the space to feel larger, consider it on an accent wall only, or choose a lighter aqua for full coverage.
It can, but the green undertone will become more prominent in cool north light, pushing the color toward teal. Sample it in that light specifically before committing, and make sure you are comfortable with the teal direction.
Eggshell is a reliable choice for most living spaces and bedrooms because it gives a slight sheen that helps the color stay lively without showing every imperfection. Use satin or semi-gloss in bathrooms and kitchens where moisture and cleaning are factors.
