Jet Blue
What Jet Blue Actually Looks Like
Jet Blue CC-870 reads as a deep, dark navy blue with noticeable gray in its composition. It sits well below mid-tone, so it absorbs a significant amount of light and creates a serious, enveloping quality on walls. In bright rooms or direct sunlight it shows its blue character clearly. In low or north-facing light it can read almost like a charcoal or near-black, with just enough blue to keep it from feeling purely neutral.
Jet Blue Undertones
The hex and RGB values place this color firmly in blue-gray territory. The gray component is real and consistent, which keeps the color from feeling purely cool or purely nautical. It does not pull green or purple in most conditions. The gray softens it slightly compared to a true cobalt or royal navy, giving it a more restrained, muted quality overall.
Where Jet Blue Works Best
Because the LRV is very low, this color changes a room dramatically. It suits spaces where you want full commitment to a dark, atmospheric look. Accent walls are a natural fit. Rooms with ample natural light can handle it on all four walls without feeling oppressive. Small spaces with little light can feel very closed in, so consider that tradeoff honestly before going wall to wall in a tight powder room or windowless hallway.
Where to put Jet Blue
On all four walls in a living room with good south or west light, Jet Blue creates a cocooning quality that works well in the evening and holds its color character during the day. Keep trim white and bring in warm textures like wool, leather, or wood to balance the coolness.
A dark, focused color like this suits a dedicated home office where concentration matters more than openness. Pair it with a warm wood desk and warm-toned lighting. Avoid relying on overhead cool-white LEDs, which push the blue toward a starker, harder feel.
In a bedroom Jet Blue encourages a restful, low-stimulation environment. It works on all walls if the room gets decent natural light during the day. Use warm bedding, natural fibers, and incandescent or warm LED bulbs at night to keep the room feeling inviting rather than cold.
A formal or semi-formal dining room is one of the strongest applications. Candlelight and warm pendant lighting make the dark blue walls glow at night. The gray undertone keeps it grounded so the room feels sophisticated without being overly trendy.
Benjamin Moore lists this color as available for exterior use. On an exterior it reads as a classic deep navy. It suits traditional, craftsman, and coastal architecture well. White trim is the straightforward choice. Consider the roof and hardscape colors carefully, as a very dark wall color amplifies mismatches in the surrounding palette.
What to Pair With Jet Blue
No formal coordinating palette is listed for this color, but a few general directions work well given its blue-gray depth. Crisp whites with no yellow pull let the dark navy read clearly without muddying. Warm wood tones and natural linen fabrics break up the coolness without fighting it. Brass and warm gold hardware reads sharp against it. Soft warm off-whites on trim keep the contrast high without going stark.
Colors that clash with Jet Blue
Pairing Jet Blue walls with cool blue-gray tile or cool gray hardwood can flatten the whole room into a single cold, undifferentiated tone with no visual contrast.
High-kelvin cool-white bulbs push Jet Blue toward a harder, harsher blue and strip the gray warmth out of it, making the room feel clinical rather than atmospheric.
Choosing trim in a dark brown or charcoal that is close in value to Jet Blue reduces contrast at the edges of the wall and makes the architecture of the room disappear.
Common questions
The LRV is 8.37, which is very low. Colors below 10 absorb the majority of light in a room. That means Jet Blue will make a space feel smaller and darker, which can be exactly the intimate, enveloping effect you want, but it also means rooms with limited natural light need thoughtful layering of warm artificial light to avoid feeling dim.
Yes. Benjamin Moore offers this color for both interior and exterior applications.
For living areas and bedrooms, an eggshell balances durability with a low-sheen look that suits a deep color like this. In a dining room where you want a little more drama, matte or flat finish deepens the color further. Save satin or semi-gloss for trim, where the contrast in sheen against a flat or eggshell wall adds definition.
Sherwin-Williams Naval SW 6244 is a widely recognized deep navy in a similar dark blue-gray range and is a reasonable starting point if you are comparing across brands. Always sample both on your actual walls before deciding, since lighting conditions in your specific room will show differences that color chips cannot.
