Blue Diamond
What Blue Diamond Actually Looks Like
Blue Diamond 736 reads as a pale, watery blue-green. It sits light on the wall without feeling washed out, carrying just enough color to register as intentional. In bright natural light it leans toward a clean aqua. In lower or north-facing light it can pull greener and feel more muted, almost like sea glass. It is not a bold statement color, but it is not a whisper either. Think calm, considered, and quietly refreshing.
Blue Diamond Undertones
The undertone here is blue-green, and which side dominates depends heavily on your room. Pair it with warm neutrals or wood tones and the green comes forward. Set it next to cool whites or grays and the blue takes over. Because it sits right on that blue-green boundary, it is genuinely sensitive to its surroundings. Soft furnishings, flooring, and even the color of your trim can tip the balance noticeably from one reading to the other.
Where Blue Diamond Works Best
Blue Diamond works well in rooms where you want a sense of ease without going stark. Bedrooms benefit from its calm quality, especially in rooms with moderate to good natural light where the blue-green reads at its freshest. Washrooms and laundry rooms are practical fits too since the color holds up well in smaller spaces without closing them in, and the aqua association with water feels at home there. It would also work in a hallway or a sitting room where you want color presence but not visual weight.
Where to put Blue Diamond
In a bedroom with east or south-facing light, Blue Diamond reads at its clearest and most refreshing. The blue-green quality promotes a calm atmosphere without making the space feel clinical. Keep bedding and textiles in warm whites or natural linens to balance the cool wall color and stop it tipping too green.
A small washroom is a strong candidate for this color. The aqua feel suits a water-adjacent space, and in a tight room with artificial light you will want to check a large sample first since lower-color-temperature bulbs can push it greener. In a brighter bathroom with natural light, it stays lively and fresh.
Laundry rooms often get overlooked, but a color like Blue Diamond makes even a utilitarian space feel considered. It reads cheerful without being loud, and the light LRV keeps the room from feeling dim even when the space has limited windows.
In a hallway with decent through-light, Blue Diamond adds personality without competing with adjacent rooms. Keep trim in a cool or neutral white to let the color do its work cleanly. In a very dark hallway with no natural light, test it carefully because it can lose its brightness and flatten out.
What to Pair With Blue Diamond
Blue Diamond coordinates naturally with whites that either warm it slightly or let its cool side lead. White Dove OC-17 brings a creamy warmth that softens the aqua and keeps the overall feel inviting. Oxford White CC-30 sits cooler and less creamy, giving you a crisper contrast that plays up the blue in the color. White Diamond OC-61 is the coolest option of the three, with faint blue-sparkle qualities that reinforce the color's serene side rather than fighting it. For a more layered look, Horizon OC-53 works as a soft, hazy companion, while Tweed Coat CSP-85 and Flint AF-560 bring in warm-neutral and earthy grounding tones that keep the palette from feeling one-note.

Colors that clash with Blue Diamond
Strong yellow or golden-toned walls, floors, or furnishings in an adjacent space can make Blue Diamond look dull or slightly muddy where the two colors meet. The cool blue-green and warm yellow sit far enough apart on the spectrum to create tension rather than contrast.
Heavy orange-toned wood, think older oak or pine with a warm stain, can make the green side of Blue Diamond look more pronounced and slightly sour. The color is not a bad pairing with wood in general, but orange-based finishes are a difficult match.
If an adjacent room is painted in a blue-gray or slate, the transition from that room into Blue Diamond can feel like a color repetition rather than a shift. The two colors share enough cool-blue DNA to blur into each other rather than giving you a clear change of mood.
Common questions
The LRV is 68.93, which is on the lighter end of the scale. That high reflectivity means it will hold its brightness reasonably well even in rooms without strong natural light. That said, in a truly dark north-facing room with no direct light, the color can lose some of its aqua clarity and read flatter and greener. Always test a large swatch in your actual space before committing.
It depends on your conditions. In bright natural light and next to cool whites it tends to read bluer. In lower light or when surrounded by warm wood tones and earthy neutrals it leans greener. The color genuinely sits on the line between the two, so your room's light exposure and what you put next to it will determine which side shows up more.
It depends on the mood you want. White Dove OC-17 warms the pairing and keeps it inviting. Oxford White CC-30 is a step cooler and crisper, letting the aqua quality lead. White Diamond OC-61 is the coolest option of the three, with a faint blue quality that reinforces the serene feel. Any of these can work well. The choice comes down to whether you want the room to feel warm and soft or clean and airy.
Yes, it is a natural fit. The aqua quality works well in a water-adjacent space, and the high LRV keeps a bathroom from feeling enclosed. In a windowless bathroom, check your lighting temperature because warm artificial light can shift the color greener. In a bathroom with natural light it stays fresh and clear.
