What Color Is Sea Serpent by Sherwin Williams SW 7615?
Sea Serpent blends blue, gray, and a dash of green undertones. It’s deep and moody, with a low LRV that gives it drama without losing versatility.
Color Family
Sea Serpent sits in the blue family, but it’s not your classic bright or primary blue. It leans more toward a blue-gray base, with hints of green depending on the light.
Natural daylight makes it look like a deep navy with a softer, muted edge. Under warm artificial light, you might catch the green undertone peeking through, adding a slightly earthy vibe.
This mix helps Sea Serpent fit in both modern and traditional spaces. It’s got navy’s depth without the harshness, and the gray keeps it from feeling too much.
Color Codes (Hex, RGB, LRV)
Here’s the technical side, in case you like the details. These numbers help you match it with other colors or use it for digital design.
- Hex Code: #3E4A56
- RGB: (62, 74, 86)
- Light Reflectance Value (LRV): 7
The LRV of 7 means Sea Serpent absorbs most light, so it’s going to look dark on walls. In a small room, you’ll probably want to balance it with lighter trim or furnishings.
These codes also come in handy for coordinating with soft whites, muted greens, or warm metallics. Use them to make sure your paint, fabrics, or finishes actually work together.
Sea Serpent by Sherwin Williams SW 7615 Undertones
Sea Serpent isn’t just a flat navy. It brings blue-gray tones and a little green that keeps things from getting too stark.
The undertones shift with the light. In bright natural light, the blue stands out. In dim or artificial light, the gray and green take over.
You could say it lands somewhere between navy, teal, and charcoal. That balance makes it pretty flexible for lots of styles.
Here’s a quick breakdown:
| Undertone | Effect in Space |
|---|---|
| Blue | Adds richness and depth |
| Gray | Grounds the color, keeps it neutral |
| Green | Brings a subtle warmth and softness |
If you put it with crisp whites, the blue pops. Next to warm wood or copper, the green sneaks out a bit more.
This shifting quality gives Sea Serpent its personality and makes it feel different as the light changes.
How Does Lighting Affect Sea Serpent by Sherwin Williams SW 7615?
This color shifts a lot depending on the type and strength of light. Sometimes it’s softer, sometimes it gets deep and moody. The amount of natural or artificial light in your space really decides whether Sea Serpent feels more blue, gray, or even a touch green.
Natural Lighting
In bright natural light, Sea Serpent often looks lighter and more blue. South-facing rooms with steady daylight soften the color and keep it from feeling heavy.
In north-facing rooms, cooler light pushes the shade darker and more gray. That’s when you might notice the green undertones showing up.
Morning light brings out a fresher blue, while late afternoon casts a warmer glow that softens things a bit. If you want to see how it changes, try painting a sample on a few different walls or use a light box to mimic daylight shifts.
Artificial Lighting
Under artificial light, Sea Serpent usually deepens and gets more dramatic. Warm bulbs like soft white or incandescent highlight the blue-gray balance and make the room feel cozy, but not heavy.
Cooler bulbs—think daylight LEDs—bring out the gray and green undertones. That can make the color feel sharper or more modern, but also a bit darker.
Lamp and overhead fixture placement matters, too. Direct lighting will brighten the paint, while indirect keeps it muted and rich. Try different bulbs before you commit—seriously, it’s worth it.
Sea Serpent by Sherwin Williams SW 7615 LRV 7 (Light Reflectance Value)
This color reflects very little light, so it ends up looking deep and bold on walls or cabinets. Understanding LRV helps you decide if it’s right for your space and lighting.
What Is LRV?
LRV stands for Light Reflectance Value. It’s a measure of how much visible light a paint color bounces back. The scale goes from 0 (pure black) to 100 (pure white).
High LRV colors reflect more light and feel brighter. Low LRV colors soak up light and look darker.
You can use LRV to guess how a color will behave in a room. For example:
- High LRV (70–100): bright, airy colors
- Mid LRV (30–69): balanced, versatile tones
- Low LRV (0–29): rich, dark shades
Knowing the number gives you a sense of how the color will actually look on your walls.
Sea Serpent by Sherwin Williams SW 7615 LRV Range
Sea Serpent sits at an LRV of 7, so it’s definitely in the very dark range. It absorbs most light, giving the color a strong, moody vibe.
In daylight, it reads as a deep navy with a little gray. Under warm artificial light, you might catch those green undertones.
With such a low LRV, you’ll want to balance it out with lighter trim, furniture, or textiles. Pair it with soft whites, creams, or light woods to keep things from feeling too heavy.
On an accent wall or cabinetry, the low reflectance creates a striking contrast against brighter surfaces, making the space feel sharper and more polished.
Sea Serpent by Sherwin Williams SW 7615 Coordinating Colors
Pairing Sea Serpent with the right colors really helps balance its deep blue vibe. Light neutrals can soften it, while darker shades add more depth and drama.
Snowbound SW 7004
Snowbound SW 7004 makes a great trim or wall color to lighten up Sea Serpent. This cool white has subtle undertones that shift with the light, sometimes going a bit warm or gray. That flexibility makes it a solid choice for modern or classic rooms.
Snowbound keeps Sea Serpent from overwhelming the space and creates a clean frame that shows off the blue. Together, they balance each other—depth from Sea Serpent, freshness from Snowbound. If you want to see how Snowbound SW 7004 adapts in different rooms, it’s worth checking out.
Agreeable Gray SW 7029
For a softer contrast, Agreeable Gray SW 7029 is a go-to. This greige blends gray and beige, so it’s warmer than a standard gray but neutral enough to handle bold colors. It helps transition Sea Serpent into spaces with wood, natural textures, or sheepskin accents.
Using Agreeable Gray on big walls and Sea Serpent for accents gives you a cozy but refined look. The warmth in Agreeable Gray keeps the deep blue from feeling too cold. If you’re after a versatile neutral that balances bold tones, give Agreeable Gray SW 7029 a look.
Inkwell SW 6992
If you want a dramatic, moody palette, Inkwell SW 6992 is a strong partner for Sea Serpent. Inkwell is an almost-black blue with serious depth, darker and more intense than Sea Serpent. Used together, they create a layered, monochromatic effect.
You might put Inkwell on cabinets, doors, or an accent wall, with Sea Serpent on larger areas. This combo works best in rooms with lots of natural light, so it doesn’t get too closed-in.
Adding lighter touches like white trim, metallic finishes, or soft textures helps balance the dark tones. The result is a bold, modern look that feels intentional and a bit sophisticated.
Trim Colors for Sea Serpent by Sherwin Williams SW 7615
Pairing Sea Serpent with the right trim color is the trick to making that dark blue pop. Crisp whites with different undertones can nudge the mood from soft and welcoming to sharp and modern.
Pure White SW 7005
Honestly, you just can’t go wrong with Pure White SW 7005 if you want trim that’s clean but doesn’t scream “hospital white.” There’s a hint of warmth tucked in, so it never feels cold next to the deep blue of Sea Serpent.
That touch of softness helps it work for both modern and traditional rooms. Pure White gives your trim a crisp look, but without the harshness you sometimes get from a really bright, cool white.
It brings out the richness of Sea Serpent and keeps everything feeling balanced. If you need a trim color that adapts to different lighting, Pure White SW 7005 is about as reliable as they come.
This shade keeps bold wall colors grounded and gives rooms a polished, finished vibe.
Snowbound SW 7004
Snowbound SW 7004 leans a bit cooler than Pure White, with a subtle gray undertone running through it. That makes it a great pick if you want softer contrast—less sharp, but still bright enough to frame Sea Serpent in a nice way.
The gray in Snowbound ties together spaces with cool accents like brushed nickel or stainless steel. It keeps the trim from looking creamy, which can sometimes fight with deep blues.
Snowbound feels right at home in bedrooms or living rooms when you want a calm, cohesive look. It lets Sea Serpent stay the star, keeping trim smooth and understated.
High Reflective White SW 7757
Need maximum contrast? High Reflective White SW 7757 is as bright as Sherwin-Williams gets—no real undertones, just pure, sharp white next to dark blue.
It gives trim a crisp, modern edge, making moldings, doors, and ceilings pop. The depth of Sea Serpent gets emphasized, especially in contemporary spaces or rooms with lots of light.
But heads up: High Reflective White can feel a bit much in dim spaces. You’ll want plenty of natural light to balance out the bold contrast.
For exteriors, it creates a classic, striking look when you pair it with Sea Serpent siding. It’s a little dramatic, but sometimes that’s what you’re after.
Real World Examples of Sea Serpent by Sherwin Williams SW 7615 in Different Spaces
This deep, cool blue works for both small accents and big statements. You can use it to create contrast, highlight details, or just bring some cozy, modern vibes to your home.
Bathrooms
Sea Serpent adds depth to bathrooms without making them feel boxed in. When you put it next to white tile or marble countertops, you get a crisp, clean contrast that looks pretty sharp.
Try it on vanity cabinets if you want them to stand out, while keeping the walls light. If you’re in the mood for something bolder, paint the walls Sea Serpent and use brass or matte black fixtures for balance.
Smaller bathrooms do best with this color in moderation—maybe just an accent wall or shelving. Sea Serpent also pairs really well with natural wood, which adds a little warmth to a space that can feel chilly.
Bedrooms
In bedrooms, Sea Serpent sets a calm, restful mood. With a low Light Reflectance Value (about 7), it soaks up light and makes the space feel cozy.
Go all-in and paint every wall for drama, or just do a single wall behind the bed for a focal point. Soft white bedding and light wood furniture help keep things from getting too heavy.
If you’re working on a nursery, Sea Serpent looks great on an accent wall behind the crib. Throw in a white dresser and neutral textiles for balance. It’s a color that grows with your kid, so you won’t have to repaint every couple of years.
Front Doors
A Sea Serpent front door gives your home a modern, timeless vibe. It stands out against light siding—think white, beige, or gray.
On brick exteriors, the color creates a rich contrast and boosts curb appeal. Add matte black hardware for a sleek finish.
Since it’s a dark shade, it hides dirt and scuffs better than lighter colors. That’s a win for busy entryways.
Home Offices
Sea Serpent just works in home offices when you want focus and calm. The cool undertones cut down on visual clutter and give you a clean backdrop for getting things done.
Paint built-in shelves or a desk wall in this color to anchor the space. Light trim and neutral floors help the room feel open, not boxed in.
For a two-tone look, pair Sea Serpent with a lighter neutral like Shoji White up top. That way, you keep things balanced and avoid making the room too dark—especially during long workdays.
Houses
On exteriors, Sea Serpent comes off as a sophisticated dark blue-gray. It looks great on siding, especially with crisp white trim.
For a more modern vibe, try it with black windows and natural wood accents. You get a style that’s both current and classic.
Because it doesn’t reflect much light, it can look almost black in the shade. But in bright sun, the blue stands out more. That versatility makes it a solid pick for all sorts of climates and lighting.
Kitchen Cabinets
People love Sea Serpent for kitchen cabinets—it brings contrast without being too in-your-face. On lower cabinets, it pairs nicely with white uppers and a light backsplash.
Paint the island Sea Serpent to make it the kitchen’s centerpiece. Brass or gold hardware adds warmth and keeps the space from feeling chilly.
In smaller kitchens, just use it on the island or one section. A Sea Serpent island with white cabinets around it keeps things bright but still adds some depth.
Living Rooms
Sea Serpent in living rooms creates a cozy backdrop, whether your style is modern or traditional. It looks especially nice with warm leather or light linen fabrics.
Try it on built-ins, an accent wall, or even the fireplace to give the room some character. Light rugs and neutral sofas keep the space from feeling too dark.
If you want that layered, lived-in look, combine Sea Serpent with wood coffee tables and soft white curtains. It’s a nice way to make the room inviting without losing depth.

Sea Serpent’s gray undertone makes it easier to pair with soft whites and warm woods. Indigo Batik, though, brings more energy into a room.
In natural light, Indigo Batik brightens up, while Sea Serpent stays deep and shadowy. For smaller spaces, Indigo Batik might help keep things from feeling too tight.
Sea Serpent by Sherwin Williams SW 7615 vs Loyal Blue SW 6510
Loyal Blue SW 6510 is a strong, saturated blue with barely any gray. It feels fresher and more vibrant—almost like a royal blue next to Sea Serpent’s stormy navy-gray.
Loyal Blue really grabs attention, so it’s awesome as an accent. Sea Serpent is quieter and more sophisticated, so it works better on big walls or even outside.

Sea Serpent by Sherwin Williams SW 7615 vs Dress Blues SW 9176

Charcoal Blue SW 2739 sits closer to a true navy, but it’s a bit darker and more charcoal-like. Compared to Sea Serpent, it feels heavier and more dramatic, for sure.
Sea Serpent’s gray undertones make it easier to live with day-to-day, while Charcoal Blue can be intense or even formal. If you want a statement color, Charcoal Blue is up to the task.
