Nautilus
What Nautilus Actually Looks Like
Nautilus is a clear, saturated blue with a definite teal lean. Think of a swimming pool catching afternoon sky, not the deep ocean. It reads confident without being loud, sitting right in that sweet spot between aqua and true blue. At LRV 41.8, it has enough depth to anchor a wall but enough brightness to keep a room feeling open. In natural daylight it sparkles with energy. Under warm incandescent light it softens and pulls slightly greener. Cool LED light pushes it bluer and crisper. North-facing rooms will emphasize its cooler side, while south-facing light warms it up and brings out the teal character.
Nautilus Undertones
The primary undertone is blue, plain and simple. But there is a secondary teal quality that shows up in certain light, especially warm afternoon sun or rooms with a lot of natural wood. Some designers read it as a clean tropical blue, while others insist they see green creeping in. Both camps are right, it just depends on the light and surroundings. What you will not find here is gray or purple. Nautilus stays clean and chromatic. If you put it next to a true teal, it looks bluer. Put it next to a pure blue, and the teal surfaces. That chameleon quality is actually one of its strengths.
Where Nautilus Works Best
Nautilus works well across a range of applications. It is saturated enough for an accent wall in a living room but friendly enough for an all-walls treatment in a bathroom or bedroom. On exteriors, it makes a lively front door or shutter color, especially against white or warm gray siding. It is a natural fit for coastal, midcentury, and transitional styles. Because of its medium depth at LRV 41.8, it pairs well with both light and dark trim without looking washed out or overpowering. Use it on cabinetry in a bathroom for a fresh, spa-like feel. For kids' rooms or playrooms, it brings energy without the intensity of a navy or cobalt.
Where to put Nautilus
Nautilus turns a bedroom into a restful retreat without putting it to sleep. Use it on all four walls and pair with warm white bedding and natural wood nightstands. The blue-teal tone is calming but has enough life to keep the room from feeling cold. If the room is small, stick to one accent wall behind the headboard and paint the remaining walls in a warm white.
This color was practically made for bathrooms. Against white tile and chrome fixtures, Nautilus reads fresh and clean. On a vanity, it adds personality without overwhelming a small space. Pair it with brass hardware if you want a warmer, more collected look. The color holds up well in the high humidity and variable lighting typical of bathrooms.
In a living room, Nautilus works best as an accent wall or on built-in shelving. It gives the room a focal point and plays nicely with neutral upholstery in warm taupes, creams, or even charcoal. Full room coverage can work in a space with plenty of natural light and warm wood floors to balance the cool tone.
If you want impact without commitment, a single Nautilus accent wall delivers. It is saturated enough to read as intentional but not so dark that it closes in the room. Try it behind a dining table, a fireplace, or as a backdrop for open shelving. Keep the other walls in a warm white or very pale blue for contrast.
Nautilus is a bold exterior choice that pays off, especially on a front door, shutters, or as a body color on a beach house. Expect it to look a touch lighter and cooler in direct sunlight than it does on the swatch. Pair with crisp white trim and a warm neutral like a sandy beige for the remaining surfaces.
What to Pair With Nautilus
Nautilus looks best when its cool energy is balanced by warmth or grounded by a neutral. Greek Villa (SW 7551) is your go-to trim color here, a creamy warm white that softens the blue without competing. Sky High (SW 6504) works as a lighter companion on ceilings or upper walls if you want a tonal blue scheme. Cityscape (SW 7067), a mid-tone cool gray, is the anchor, great for an adjacent hallway, lower cabinets, or furniture pieces that need to tie the palette together.

A warm creamy white like Greek Villa (SW 7551) is a reliable trim partner. It softens the cool blue without looking stark. Bright pure white trim also works but will make the contrast sharper and more modern.
