Hidden Sapphire CSP-690 by Benjamin Moore

If you’re looking for a paint color that brings depth, sophistication, and a touch of serenity to your home, Benjamin Moore’s *Hidden Sapphire* (CSP-690) might just be your perfect match. This deep blue hue, with its rich, ocean-like quality, has a way of transforming spaces into calming retreats while still making a bold statement. Whether you’re considering it for a living room, bedroom, or even a home office, this color has the versatility to adapt to your vision—but let’s dive deeper into what makes it so special.

First, let’s talk about the color itself. *Hidden Sapphire* is a dark blue with an LRV (Light Reflectance Value) of just 6.21%, meaning it absorbs light rather than reflecting it. This gives it an almost mysterious depth, like the quiet stillness of deep water. In natural light, it feels vibrant and alive, while in dimmer settings, it takes on a moodier, more dramatic presence. That adaptability makes it a fantastic choice for rooms with varying light conditions—just be mindful that in smaller spaces, it can feel a bit cozy (which some love) or slightly closed-in (which others might want to balance with lighter accents).

One of the standout features of this paint is its ease of application. Whether you’re a DIY beginner or a seasoned pro, you’ll appreciate how smoothly it rolls on, with excellent coverage in just one or two coats. The finish options—matte, satin, or semi-gloss—give you flexibility depending on the look and durability you need. If you’re using it in a high-traffic area like a hallway or living room, a satin or semi-gloss finish will hold up better to scrubbing and daily wear. Just keep in mind that higher-gloss finishes can show fingerprints more easily, so factor that into your decision.

Now, let’s talk about pairing *Hidden Sapphire* with other colors. Its cool undertones make it a natural companion for crisp whites like *White Dove* or *Pure White* on trim and ceilings—this contrast keeps the space feeling fresh and intentional. If you want to warm it up a bit, try pairing it with earthy neutrals or even a soft blush (its complementary hue is a subtle red, which can create a striking balance). For a more monochromatic look, layer it with lighter blues from the same family, like *2055-20* or *2058-30*, to add dimension without overwhelming the space.

Where does this color shine the brightest? Think accent walls in a home office for a focused, serene vibe, or full-room applications in a bedroom where you want to create a cocoon-like retreat. It also works beautifully in dining rooms, especially when paired with warm wood tones and metallic accents for a touch of elegance. And if you’re going for a modern farmhouse or coastal look, *Hidden Sapphire* fits right in—its deep blue tone evokes the ocean, making it a natural fit for beachy or nautical themes, while its richness keeps it grounded in more traditional or industrial settings.

A few practical tips: always test the color in your space before committing. Paint a large swatch and observe it at different times of day to see how the light plays with its undertones. If you’re worried about it feeling too dark, consider using it on lower wainscoting or cabinetry instead of full walls. And don’t forget lighting—strategic lamps or sconces can enhance its depth and keep the room from feeling too shadowy.

One of the best things about *Hidden Sapphire* is its durability. This isn’t just a pretty color—it’s also low-VOC, eco-friendly, and resistant to fading, so it’ll stay vibrant for years. Touch-ups are a breeze, and its stain-resistant quality means it can handle the occasional splash or scuff without losing its charm.

So, is *Hidden Sapphire* right for your home? If you love moody, cool tones that bring a sense of calm and sophistication, absolutely. It’s a color that works hard to create atmosphere while being surprisingly easy to live with. Whether you’re going for a dramatic statement or a subtle backdrop, this deep blue has the versatility to deliver. Just remember: great design is about how a color makes you feel. If walking into a room painted this shade feels like a deep breath of calm, you’ve found your match.

At the end of the day, paint is one of the most transformative tools in home design, and *Hidden Sapphire* is a standout choice for anyone looking to infuse their space with depth, tranquility, and a touch of timeless elegance. So grab a sample, see how it looks in your light, and get ready to fall in love with your walls all over again.

Understanding Color Properties and Interior Design Tips

Hue refers to a specific position on the color wheel, measured in degrees from 0 to 360. Each degree represents a different pure color:

• 0° represents red
• 120° represents green
• 240° represents blue

Saturation describes the intensity or purity of a color and is expressed as a percentage:

• At 0%, the color appears completely desaturated—essentially a shade of gray
• At 100%, the color is at its most vivid and vibrant

Lightness indicates how light or dark a color is, also expressed as a percentage:

• 0% lightness results in black
• 100% lightness results in white

Using Warm Colors in Interior Design

Warm hues—such as reds, oranges, yellows, warm beiges, and greiges—are excellent choices for creating inviting and energetic spaces. These colors are particularly well-suited for:

• Kitchens, living rooms, and bathrooms, where warmth enhances comfort and sociability
• Large rooms, where warm tones can help reduce the sense of emptiness and make the space feel more intimate

For example:

• Warm beige shades provide a cozy, inviting atmosphere, ideal for living rooms, bedrooms, and hallways.
• Warm greige (a mix of beige and gray) offers the warmth of beige with the modern appeal of gray, making it a versatile backdrop for dining areas, bedrooms, and living spaces.

However, be mindful when using warm light tones in rooms with limited natural light. These shades may appear muted or even take on an unpleasant yellowish tint. To avoid a dull or flat appearance:

• Add depth by incorporating richer tones like deep greens, charcoal, or chocolate brown
• Use textured elements such as curtains, rugs, or cushions to bring dimension to the space

Pro Tip: Achieving Harmony with Warm and Cool Color Balance

To create a well-balanced and visually interesting interior, mix warm and cool tones strategically. This contrast adds depth and harmony to your design.

• If your walls feature warm hues, introduce cool-colored accents such as blue or green furniture, artwork, or accessories to create contrast.
• For a polished look, consider using a complementary color scheme, which pairs colors opposite each other on the color wheel (e.g., red with green, orange with blue).

This thoughtful mix not only enhances visual appeal but also creates a space that feels both dynamic and cohesive.

Light Temperature Affects on Hidden Sapphire

Natural Light

Natural daylight changes in color temperature as the sun moves across the sky. At sunrise and sunset, the light tends to have a warm, golden tone with a color temperature around 2000 Kelvin (K). As the day progresses and the sun rises higher, the light becomes cooler and more neutral. Around midday, especially when the sky is clear, natural light typically reaches its peak brightness and shifts to a cooler tone, ranging from 5500 to 6500 Kelvin. This midday light is close to what we perceive as pure white or daylight-balanced light.

These shifts in natural light can significantly influence how colors appear in a space, which is why designers often consider both the time of day and the orientation of windows when planning interior color schemes.

Artificial Light

When choosing artificial lighting, pay close attention to the color temperature, measured in Kelvin (K). This determines how warm or cool the light will appear. Lower temperatures, around 2700K, give off a warm, yellow glow often used in living rooms or bedrooms. Higher temperatures, above 5000K, create a cool, bluish light similar to daylight, commonly used in kitchens, offices, or task areas.

LRV of Hidden Sapphire

The Light Reflectance Value (LRV) of Hidden Sapphire is 6.21%, which places it in the Dark colors category. This means it does not reflect light. Understanding a paint’s LRV is crucial for predicting how it will look in your space. A higher LRV indicates a lighter color that reflects more light, making rooms feel larger and brighter. A lower LRV signifies a darker color that absorbs more light, creating a cozier, more intimate atmosphere. Always consider the natural and artificial lighting in your room when selecting a paint color based on its LRV.
