Aquarium Blue
What Aquarium Blue Actually Looks Like
Aquarium Blue sits right in the middle of the value scale, bright enough to feel fresh but saturated enough to have real presence on a wall. Think of a clear shallow bay on a sunny afternoon, that particular blue that is neither green nor grey but holds its own identity. It reads as a clean, cool blue in most conditions, shifting slightly softer in overcast light and a touch more vibrant when direct sun hits the wall.
Aquarium Blue Undertones
The color carries subtle cyan leanings that keep it from drifting into a flat, chalky blue. There is very little green and very little grey in it under most lighting conditions, which makes it read as a fairly pure, honest blue. In rooms with warm incandescent lighting it can settle into a slightly more muted, tranquil tone, but it does not shift dramatically toward any one undertone the way a more complex blue might.
Where Aquarium Blue Works Best
Because its LRV lands near the midpoint, Aquarium Blue works on both full walls and as an accent without overwhelming or disappearing. It suits spaces where you want a sense of calm and openness. Bathrooms, bedrooms, and covered porches are natural fits. It also holds up well on exterior shutters or front doors where you want a distinctly blue statement that is not navy and not baby blue.
Where to put Aquarium Blue
Aquarium Blue on bedroom walls creates a restful, cool atmosphere without feeling cold or clinical. Keep bedding and textiles in warm whites and natural linens to balance the coolness of the blue and add depth to the room.
In a bathroom, especially one with natural light and white fixtures, this color reads clean and spa-like. It complements chrome and brushed nickel hardware particularly well, and the mid-tone saturation holds up against the bright reflections common in wet rooms.
As an exterior color on shutters, a front door, or a coastal cottage body, Aquarium Blue reads cheerful and distinctive in full sun without veering toward the predictable navy territory. It pairs naturally with white trim and weathered wood details.
In a shaded porch or sunroom with indirect light, the color holds its brightness better than pale blues do, which often wash out or turn grey. It keeps the space feeling like an extension of the outdoors.

Common questions
The Benjamin Moore color code is 2058-50 and the LRV is 47.73, placing it solidly in the mid-tone range. It reflects a moderate amount of light, so it works in rooms with decent natural light but will feel a bit heavier in rooms with very little light.
Yes, it is available in both interior and exterior Benjamin Moore formulas, which makes it versatile for indoor walls as well as exterior applications like shutters, doors, or siding.
Under most natural light it stays a fairly clean blue with a hint of cyan. In rooms with heavy warm artificial lighting it can settle slightly and lose some of its brightness, but it does not typically shift strongly toward green or grey the way a more complex blue-green would.
Eggshell is a reliable choice for living spaces and bedrooms because it is easy to clean and avoids the flat appearance that can make mid-tone colors look chalky. In bathrooms or kitchens, satin provides extra moisture resistance while still showing the color accurately.
