Casco Bay
What Casco Bay Actually Looks Like
Casco Bay is a rich, saturated teal that sits squarely between blue and green. It reads as a deep sea color, the kind that evokes cool saltwater and aged patina copper. It is dark enough to feel grounding on a wall but has enough green-blue complexity to stay interesting. In bright natural light it opens up and shows its full teal character. In low or artificial light it can read almost like a deep forest green, or shift toward a muted navy depending on the light source.
Casco Bay Undertones
The color carries both blue and green undertones in close balance. Neither dominates cleanly. In warm incandescent light the green side can come forward. In cooler daylight the blue reads more clearly. There is no significant gray or brown pull, which keeps it feeling clean rather than muddy.
Where Casco Bay Works Best
Casco Bay works well anywhere you want a color with real depth and presence. It is a strong candidate for a front door, where its intensity reads as confident and distinctive without being aggressive. On interior walls it suits spaces where you want to create atmosphere, a home office, a dining room, a library, or a powder room. Because its LRV is low, it absorbs light, so it is better suited to rooms where you want enclosure and mood rather than brightness. It can also work beautifully on cabinetry, built-ins, or exterior trim.
Where to put Casco Bay
A dining room in Casco Bay creates an intimate, enveloping atmosphere that works well for evening meals. Candlelight or warm pendant lighting will shift it slightly toward green and add warmth. Pair with natural wood furniture and brass fixtures to keep the space from feeling cold.
On a front door, Casco Bay reads as a confident, saturated teal that stands apart from standard navy or black doors. It suits both traditional and transitional exteriors. A semi-gloss or gloss finish will add depth and make the color pop against brick, gray siding, or white trim.
The depth of this color makes a home office feel focused and settled. It reduces visual distraction and gives the space a sense of purpose. Use adequate task lighting since the low LRV means the room will not reflect much light back on its own.
A powder room is a low-commitment way to try a dark teal at full saturation. The small scale makes the intensity feel intentional rather than overwhelming. Warm metals and a statement mirror finish the look well.
Casco Bay on kitchen island cabinetry or living room built-ins adds a layer of color without committing entire walls. It pairs well with warm white upper cabinets and brass or unlacquered brass pulls.
What to Pair With Casco Bay
No coordinating colors are specified in our database for Casco Bay 2051-30, but the color pairs naturally with warm off-whites, aged brass or unlacquered brass hardware, natural wood tones, and warm terracotta or rust accents.

Colors that clash with Casco Bay
Placing Casco Bay adjacent to a cool blue-gray in an open floor plan can make both colors compete and feel disconnected, since neither provides the warm contrast the other needs.
Chrome fixtures or cool silver hardware can pull Casco Bay in a harsh, cold direction, emphasizing any blue in the teal and stripping out warmth.
Because this color has a low LRV, it absorbs a significant amount of light. In a windowless or very small room, it can make the space feel noticeably darker and more compressed than intended.
Common questions

It sits close to the middle of the blue-green range. In warm light it tends to read greener. In cool daylight the blue comes through more clearly. You will see both depending on your light source and time of day.
An eggshell finish works well for most interior wall applications. It provides a slight sheen that helps the depth of the color read without highlighting imperfections. For cabinetry or a front door, move to a semi-gloss or gloss to make the color more durable and vivid.
Yes. Benjamin Moore lists it as available in exterior formulas. It works particularly well on front doors and shutters. On full exterior siding it makes a bold statement, best suited to homes where you want clear, confident color rather than something recessive.
For a color this dark, a tinted primer is strongly recommended. Ask your paint desk to tint the primer toward the color. It reduces the number of finish coats needed for full, even coverage.
