Casco Bay 2051-30 by Benjamin Moore

If you’re searching for a paint color that effortlessly blends sophistication with tranquility, let me introduce you to Benjamin Moore’s Casco Bay. This stunning teal shade (color code 2051-30) is a deep, moody hue with a blue undertone that brings a sense of calm and refinement to any space. Whether you’re refreshing a bedroom, revamping a home office, or giving your bathroom a spa-like feel, Casco Bay might just be the perfect choice. But before you grab a paintbrush, let’s dive into everything you need to know about this captivating color—so you can decide if it’s the right fit for your home.

First, let’s talk about the color itself. Casco Bay sits right at the intersection of blue and green, creating a rich teal that feels both timeless and on-trend. Its LRV (Light Reflectance Value) of 15.13% means it reflects very little light, giving it a medium-dark depth that works beautifully as an accent wall or even on all four walls in the right space. The blue undertone keeps it cool and serene, making it ideal for rooms where you want to unwind, like a bedroom or bathroom. But don’t let the “dark” label scare you—this color has enough vibrancy to avoid feeling heavy when used thoughtfully.

One of the standout qualities of Casco Bay is its versatility. It plays well with a range of decor styles, from coastal and modern to transitional and eclectic. In a coastal-themed room, it evokes the tranquil waters of its namesake, pairing effortlessly with crisp whites, natural wood tones, and woven textures. For a modern look, try it alongside sleek furniture and metallic accents. If your style leans more eclectic, don’t be afraid to mix it with bold patterns or vibrant artwork—the depth of Casco Bay provides a grounding effect that keeps the space from feeling chaotic.

Now, let’s address the elephant in the room: lighting. Because Casco Bay reflects so little light, it can appear darker in rooms with limited natural light. If you’re working with a small or dimly lit space, consider using it as an accent wall rather than covering the entire room. Pair it with lighter neutrals like Simply White or soft grays to keep the space feeling open and airy. And if you’re committed to going all-in, amplify the light with mirrors, layered lighting, and glossy finishes to bounce light around the room. In well-lit spaces, though, Casco Bay truly shines—its teal tones come alive, shifting subtly throughout the day as the light changes.

Application is a breeze with this paint. It’s beginner-friendly, roller-ready, and fast-drying, with low splatter to keep cleanup simple. The coverage is excellent—you’ll likely only need one or two coats, even over darker colors. Plus, it’s self-priming, which saves you a step. Choose from matte, eggshell, satin, or semi-gloss finishes depending on the room’s needs. For high-traffic areas like living rooms or entryways, satin or semi-gloss offers durability and easy cleaning. In a bedroom or home office, matte or eggshell can enhance the cozy, sophisticated vibe.

Worried about maintenance? Don’t be. Casco Bay is highly washable, stain-resistant, and even mildew-resistant, making it a practical choice for bathrooms and kitchens. And since it’s low-VOC and eco-certified, you won’t have to deal with strong odors or harmful fumes—a win for your health and the environment.

When it comes to pairing Casco Bay with other colors, you’ve got options. For a harmonious look, stick with cool neutrals like whites, grays, and soft blues. If you want to add contrast, introduce warm metallics like brass or gold, or even a touch of coral or blush for a unexpected pop. Trim painted in Simply White or Pure White keeps the look crisp and polished. And if you’re feeling bold, try pairing it with deeper shades like navy or charcoal for a moody, dramatic effect.

So, who is Casco Bay best for? If you love colors that feel rich and intentional but don’t want to commit to something overly bold, this teal is a fantastic middle ground. It’s perfect for creating a restful bedroom retreat, a grounding home office, or a spa-like bathroom. It also works wonders in open-concept spaces, where it can define an area without closing it in. Just remember: if your existing decor leans heavily warm (think lots of reds, oranges, or yellows), the cool undertones of Casco Bay might clash. In that case, consider sampling it first to see how it plays with your palette.

Speaking of sampling, always test this color in your home before committing. Paint a large swatch on the wall and observe it at different times of day. Notice how it changes under natural light versus artificial light. See how it interacts with your furniture, flooring, and decor. This extra step ensures you’ll love the result—no regrets.

At the end of the day, Casco Bay is more than just a paint color. It’s a mood. It’s sophistication. It’s that feeling of stepping into a serene, well-designed space where everything just feels right. If you’re looking for a color that’s equal parts calming and captivating, this might be the one. So go ahead—imagine it on your walls, picture the way it’ll transform your room, and trust your instincts. After all, the best homes are the ones that feel uniquely yours.

Is  Casco Bay Cool or Warm?

Casco Bay is fundamentally a cool color, making it a great choice for creating tranquil and soothing environments. The cool tones are reminiscent of water and sky, which bring a sense of calmness and peace to any room. Its coolness also makes it versatile enough to be used in both contemporary and traditional settings, complementing a wide range of decor elements.

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 Casco Bay

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.
