The Seafoam Color Code: HEX, RGB, CMYK

Seafoam color is a cool, tertiary hue that blends soft green, blue, and a trace of gray into one of the most quietly versatile tones in the color spectrum.

It sits between green and cyan on the color wheel, with RGB values typically around (159, 226, 191), giving it that light, washed-out aqua quality that feels both fresh and calm at the same time.

The color has roots in mid-century design, a strong presence in coastal interiors and spring fashion, and a well-established role in wellness branding.

This article covers everything you need to know, from its exact color codes and analogous color pairings to how it holds up in paint, print, and digital design.

Seafoam Color Codes

Seafoam is a light, soft blue-green hue sitting between green and cyan on the color theory spectrum. Its exact values vary slightly across sources, but the most widely used reference point is #9FE2BF.

• HEX: #9FE2BF
• RGB: 159, 226, 191
• CMYK: 30% cyan, 0% magenta, 15% yellow, 11% black
• HSL: 149°, 54% saturation, 75% lightness
• Pantone: PMS 7478 C

In the RGB color model, seafoam leans heavily green (226) with moderate red (159) and blue (191), producing its soft, washed-out aqua tone. The CMYK breakdown confirms it as a cool-toned, low-saturation color with zero magenta.

Its hue angle of 149° places it firmly in the green-cyan range. Saturation sits at a mid-range 54%, which is exactly why it reads as calm rather than vivid. It is classified as a cool-toned tertiary color on the color wheel.

What Are the Primary Attributes of Seafoam Color?

Seafoam possesses five primary attributes: a cool blue-green hue (derived from its 149° hue angle), low-to-mid saturation (54%), high lightness (75%), soft visual weight, and a strong coastal association.

These combined traits make it read as calm and airy rather than bold or demanding. It is one of those colors that quietly works in the background without pulling too much attention.

How Is Seafoam Color Used in Interior Design?

Seafoam functions as both a foundational wall color and a soft accent in interior design, creating airy, calm spaces that visually open up a room.

Designers use it in bathrooms, bedrooms, and kitchens to establish a clean, coastal feel. It pairs naturally with white, warm neutrals, and natural wood tones.

Its mid-century modern roots (think 1950s kitchen appliances and tiled bathrooms) also make it a solid pick for vintage-inspired interiors. Works well in both minimalist schemes and more layered coastal styles.

For color-forward rooms, seafoam holds up well as a dominant wall color. For more neutral setups, it works better as an accent through cushions, rugs, or cabinet finishes. Either way, keep surrounding tones light to avoid muddying the palette.

What Psychology and Emotions Does Seafoam Color Evoke?

Seafoam evokes feelings of calm, freshness, balance, and quiet optimism through its association with ocean water and coastal nature.

Color psychology research links seafoam to emotional clarity and relaxation, making it a common choice in healthcare, wellness, and spa environments.

It also carries a mild nostalgia, something about it feels distinctly mid-century without being dated. In Eastern cultures it connects to nature and renewal. In Western contexts it leans more toward cleanliness and health.

Because the hue is desaturated and low in contrast, it does not trigger stress responses the way more saturated colors can. That makes it genuinely useful in spaces where people need to feel at ease, not just aesthetically interesting.

How Is Seafoam Color Applied in Fashion and Clothing?

Seafoam serves as a seasonal staple in spring and summer fashion, offering a soft, wearable alternative to bolder greens and blues.

Fashion designers use it in linen, chiffon, and silk garments for resort wear, bridal parties, and casual daytime looks. It suits fair and cool-toned skin undertones particularly well, though it also works with deeper complexions when the surrounding palette is light.

The color showed up in Pantone’s 2014 Spring collection under the name “hemlock” and has maintained a presence in seasonal collections since. It tends to peak in spring lines, but holds its own in summer coastal wear too.

In terms of pairing, seafoam works well with white, cream, sand, and soft coral in clothing. Navy is a tricky pairing. It can look nautical and intentional, or it can read flat, so it depends heavily on the specific shades involved.

How Does Seafoam Color Differ From Similar Cool Colors?

Seafoam differs from mint green (more purely green, less blue), teal (much darker and more saturated), turquoise (brighter, higher saturation), and aquamarine (slightly more blue-shifted) through its specific balance of green, blue, and lightness that creates its distinctly soft, washed-out character.

Seafoam is essentially the most muted and lightest of the group. Took me a while to articulate this clearly, but the key is that seafoam has gray undertones that the others lack.

See also: blue green, cyan, Tiffany blue, and celadon for related cool-toned comparisons.

How Do You Create Seafoam Color in Different Mediums?

Create seafoam by mixing phthalo green with a small amount of phthalo blue, then adding titanium white until the tone lightens and softens. In digital design, set RGB to approximately (159, 226, 191) to get accurate results on screen.

Acrylic Paint

Start with phthalo green (or viridian) as your base. Add a touch of phthalo blue, then mix in titanium white generously until the value brightens and the chroma drops.

The ratio is roughly 1 part green, small dash of blue, 3-4 parts white. Adjust toward blue if it reads too yellow-green. Add a tiny amount of gray if the result looks too vivid.

• Base colors: Phthalo green, phthalo blue, titanium white
• Mixing ratio: ~10 parts white : 3 parts green : 0.5 parts blue
• Common mistake: Adding too much blue too fast, which pushes it toward cyan
• Adjustment tip: A tiny amount of raw umber or gray tones down excess chroma

Oil Paint

Use viridian hue or phthalo green with zinc white (not titanium, which can be too opaque). Zinc white keeps the color more transparent and luminous, which suits seafoam’s soft quality.

Oil dries slightly darker, so mix slightly lighter than your target. Color shift is minimal with this palette but worth testing on a small patch first.

• Pigments: Viridian (PG18), Phthalo Green BS (PG7), Zinc White (PW4)
• Drying shift: Slight darkening, especially with phthalo-based greens

Watercolor

Phthalo green or viridian mixed with a very diluted phthalo blue, applied with heavy water content. Build the tone in layers rather than mixing a single dense wash.

The more water you use, the closer you get to seafoam’s naturally light, airy quality. Avoid opaque whites in watercolor as they muddy the transparency.

• Pigment selection: Transparent phthalo green over opaque chromium oxide
• Dilution: High water ratio, 4:1 water to pigment minimum
• Layering: Two to three thin washes build the tone better than one heavy application

Gouache

Mix phthalo green, a touch of cerulean blue, and titanium white. Gouache is more forgiving than watercolor since you can rework it. Aim for a flat, opaque finish.

Because gouache dries lighter than it looks wet, test a patch and let it dry fully before committing to a large area.

Print / CMYK

• Cyan: 30%
• Magenta: 0%
• Yellow: 15%
• Black: 11%
• Paper type: Coated stock produces cleaner, more accurate results. Uncoated paper will absorb more ink and shift the tone slightly warmer.
• Pantone match: PMS 7478 C (coated), PMS 7478 U (uncoated)

Need to convert between color spaces quickly? Use the HEX to RGB Converter or the CMYK to RGB converter for precise cross-medium accuracy. A color contrast checker is also useful when applying seafoam in UI or print contexts where readability matters.

What Are the Best Practices for Using Seafoam Color in Design?

Best practices for seafoam include pairing it with warm neutrals, checking contrast ratios for accessibility, avoiding placement against cool grays, and using it at 30-60% coverage rather than as a full dominant tone in high-density layouts.

Designers should maintain a minimum 4.5:1 contrast ratio when using seafoam as a background with text. The color’s high lightness (75%) means dark text is almost always the right call.

In web design, seafoam performs well as a section background, card fill, or button state. It rarely works as a primary action color because it lacks the visual weight to command attention. As a secondary or supporting tone, though, it holds up well.

For print design, always request a press proof before production. CMYK output varies between printers and paper stocks, and seafoam’s subtle tone can shift noticeably if ink density is off.

In terms of visual hierarchy, seafoam works best at the base or mid-level of a composition. Pair it with stronger tones like deep navy or charcoal to create contrast at the focal point. Never use it as the sole focal point color unless the surrounding palette is even lighter.

The Gestalt principles of proximity and similarity apply here too. Grouping seafoam elements together reinforces a calm, unified section. Scattering it randomly across a layout dilutes that effect.

What Role Does Seafoam Color Play in Branding and Marketing?

Seafoam plays a supporting role in branding and marketing, communicating calm, cleanliness, and natural freshness to consumers.

Marketing research links seafoam to trust and low-stress purchase environments, making it effective for wellness, spa, organic food, and beauty brands seeking a gentle, approachable identity.

It shows up regularly in health-sector branding because it avoids the clinical coldness of pure blue while retaining its association with cleanliness. That is a tricky balance to pull off with other colors.

In logo design, seafoam works best when combined with a darker anchor color. Used alone in a logo, it can read as too passive. Paired with deep navy, charcoal, or warm brown, it gains definition without losing its soft character. See logo design principles for more on how color weight affects brand recognition.

For brand guidelines that include seafoam, specify both the Pantone reference (PMS 7478 C) and the RGB/HEX values to ensure consistency across digital and print touchpoints. Color drift between mediums is a real problem with pastel tones, and seafoam is no exception. Using a brand style guide that pins down exact values across all formats saves a lot of back-and-forth with printers and developers.
