Open Seas
What Open Seas Actually Looks Like
Open Seas reads as a mid-tone coastal blue that sits comfortably between a classic blue and a soft teal. It has enough color saturation to make a statement without overwhelming a room, landing in that sweet spot where blue feels both calming and interesting. In person it looks like the color of water on a clear but overcast day. Not pastel, not dark, just solidly in the middle of the blue spectrum with a noticeable cool lean.
Open Seas Undertones
The primary undertone here is blue, but you will also pick up on a teal or blue-green quality that keeps it from reading as a straight denim or nautical blue. Some designers see more green in it than others, especially in north-facing rooms where cool light amplifies the teal side. In south-facing rooms with warm afternoon sun, it can shift slightly warmer and look more like a straightforward sky blue. The cool undertone is consistent regardless of light, so if you are looking for a blue that leans warm or has any gray softness to it, this is not it. Open Seas commits to being blue, with just enough green mixed in to give it personality.
Where Open Seas Works Best
Open Seas works well as a full-room wall color in bedrooms and bathrooms where you want that coastal, spa-like quality without going too pale or too dramatic. With an LRV of 39.1, it absorbs a moderate amount of light, so it reads best in rooms with decent natural light or good overhead lighting. It is a strong choice for an accent wall in a living room, especially paired with lighter neutrals on the remaining walls. On exteriors, it makes a striking front door or shutter color, and it can work as a full body color on coastal or cottage-style homes. For bathrooms, it pairs naturally with white tile and chrome fixtures. In bedrooms, it creates a restful backdrop without feeling too dark or heavy.
Where to put Open Seas
Open Seas on all four walls creates the kind of restful blue envelope that helps a bedroom feel like a retreat. Pair it with Dover White on the trim and ceiling. Add warm linen bedding and natural wood furniture to keep the room from feeling too cold. The LRV of 39.1 means it will not make a bedroom feel cave-like, but you will want good window light or warm-toned lamps to balance the cool lean at night.
This is one of those blues that was practically made for bathrooms. Use it on the walls with white subway tile and brushed nickel hardware. The teal undertone picks up beautifully against white fixtures and gives the space a clean, collected feel. In a windowless bathroom, make sure you have bright white lighting so the color does not read too dark or too green.
In a living room, consider Open Seas on an accent wall or fireplace surround rather than all four walls. It has enough saturation that a full room can feel intense depending on the size and light. Pair it with a warm creamy white on the surrounding walls, and bring in warm metals like brass or gold to play against the cool tones. A jute rug and leather furniture ground the blue nicely.
Open Seas makes an excellent accent wall color because it is bold enough to anchor a space but not so dark that it swallows light. Try it behind a bed headboard, behind open shelving, or on a dining room feature wall. Keep the adjacent walls in a warm white to let it take center stage.
On an exterior, Open Seas reads as a classic coastal blue. It works well as a front door color against a white or light gray body. As a full body color, it suits cottage and beach-style homes, especially when paired with crisp white trim. Keep in mind that exterior light will make it look slightly lighter and more saturated than your swatch suggests.
What to Pair With Open Seas
Open Seas pairs beautifully with warm whites that take the edge off its cool blue lean. Dover White (SW 6385) is the go-to trim companion here. Its creamy warmth prevents the blue from feeling sterile or icy. You can build a layered palette by adding warm wood tones and soft sandy neutrals alongside these two.

Colors that clash with Open Seas
In north-facing rooms or spaces with limited natural light, the cool blue and teal undertones intensify. The room can feel chilly or even slightly institutional.
Open Seas has real color presence. Pairing it with other saturated hues like coral, bright yellow, or kelly green can create visual tension that feels busy rather than intentional.
Some people expect it to read as a blue-gray, but it does not have enough gray to qualify. If you are looking for a blue-gray, this will look too saturated and too blue on your walls.
Common questions
Open Seas has an LRV of 39.1, placing it squarely in the medium range. It reflects a moderate amount of light, so it will not brighten a dark room the way a light blue would, but it also will not make a well-lit room feel heavy.
It reads primarily as blue with a secondary teal or blue-green undertone. The balance shifts depending on your light. In warm, south-facing light it looks more purely blue. In cooler light it picks up more teal. Most people see it as blue first, teal second.
Dover White (SW 6385) is the recommended trim pairing. Its warm, creamy tone balances the cool blue without the stark contrast of a bright white. If you prefer a crisper look, a clean white trim works too, but it will emphasize the coolness.
Yes. Open Seas works well on exteriors, especially for coastal or cottage-style homes. Expect it to look slightly lighter and more vivid outside than it does on an interior swatch, since direct sunlight amplifies both brightness and saturation.
