Loch Blue
What Loch Blue Actually Looks Like
Loch Blue is a rich, saturated teal that sits right at the intersection of blue and green. Think deep lake water on an overcast day. It reads decidedly bold on the wall, with an LRV of 15.6 that keeps it in solidly deep territory without tipping into navy darkness. In strong natural light, the green side of this color opens up and it can feel almost jewel-like. In dim or north-facing rooms, it shifts cooler and moodier, leaning more toward a classic deep blue. It is not a color that hides. Even on a small accent wall, it announces itself.
Loch Blue Undertones
The dominant undertone here is teal, that blue-green push that separates Loch Blue from a straight navy or a standard medium blue. You will also catch a cool, slightly gray quality in lower light, which keeps it from reading too tropical or too saturated. Some designers see the green undertone as the defining characteristic, while others read it as primarily blue with a secondary green lean. That split is worth noting because it means Loch Blue can play differently depending on the light in your space and what you pair it with. Warm wood tones tend to bring the teal forward, while cooler grays in furniture or flooring emphasize its blue side.
Where Loch Blue Works Best
Loch Blue works well on accent walls, front doors, exterior shutters, cabinetry, and built-in bookcases. Its depth makes it a strong candidate for a powder room or home office where you want color to envelop the space without feeling oppressive. On exteriors, it reads as a handsome, classic hue, especially on doors and trim details against lighter siding. Because of its LRV of 15.6, it will absorb a fair amount of light, so pair it with good lighting if you are using it on all four walls. On lower cabinets in a kitchen, it adds serious drama while keeping uppers light.
Where to put Loch Blue
Loch Blue on a headboard wall creates a cocoon-like atmosphere that is deeply calming without feeling dark. Keep bedding in warm whites and natural linens. A table lamp with a warm bulb will pull out the teal undertone and soften the mood at night.
This is one of the best uses for Loch Blue. A single wall in a living room or dining room gives you the drama of a deep color without overwhelming the space. Frame it with lighter walls in a warm off-white and let the accent wall do the heavy lifting.
In a living room, Loch Blue works as a full-room color if you have ample natural light and tall ceilings. Ground the space with a warm-toned rug and lighter upholstery. If your room runs small or dark, use it on a single wall or the built-ins instead.
On a front door, Loch Blue is a confident choice that reads as classic and a little unexpected. On shutters or exterior trim, it pairs well with warm gray or cream siding. It holds up nicely in direct sun, though it will read slightly lighter outdoors than on the swatch.
What to Pair With Loch Blue
Oyster White (SW 7637) is the coordinating trim pick for good reason. Its warm, slightly creamy tone balances the cool depth of Loch Blue without creating too stark a contrast. Brass and gold hardware play beautifully here, echoing the warmth of Oyster White while letting Loch Blue stay the star.

Colors that clash with Loch Blue
Pairing Loch Blue with a cool gray LVP or tile can make the whole room feel flat and cold. The blue-on-gray combo drains energy from the color.
A very stark, cool white trim next to Loch Blue creates a jarring contrast that can make the blue look almost artificial.
While teal and orange are technically complementary, a saturated coral throw or orange accent can create a busy, competing visual that distracts from both colors.
Common questions
Loch Blue has an LRV of 15.6, which places it firmly in the deep range. It will absorb a significant amount of light, so plan for adequate lighting in rooms where you use it on multiple walls.
It sits at the teal intersection. In warm, bright light, the green leans forward. In cooler or dimmer light, the blue dominates. Most people read it as a teal, which is accurate. If you are hoping for a straight blue, this is not it.
Oyster White (SW 7637) is the go-to coordinating trim. Its warm, creamy base softens the contrast. Avoid very cool, stark whites, which can make the pairing feel sterile.
Yes, but with intention. In a powder room or small office, it can create a dramatic, enveloping feel that actually makes the space feel intentional rather than cramped. Add warm lighting and keep the ceiling light.
