The Mint Blue Color Code: HEX, RGB, CMYK

Few colors sit as comfortably between calm and fresh as mint blue.

Mint blue is a cool, tertiary color that blends blue and green into a soft, pale cyan-leaning hue. The color carries strong associations with clarity and renewal, functioning as a low-saturation pastel on the color theory spectrum with RGB values typically around (174, 238, 238).

It shows up in interior design, fashion, branding, and digital interfaces more than most people realize.

This guide covers everything from hex codes and color palettes to color psychology, mixing methods, and real design applications.

Mint Blue Color Codes

The most widely referenced hex code for mint blue is #AEEEEE, though you’ll also see #429E9D and #B3DCD6 used depending on the context and the specific shade.

Mint blue sits in the blue-green zone of the color theory spectrum, close to cyan and teal. It’s a cool-toned pastel with low saturation and high lightness.

• HEX: #AEEEEE
• RGB: 174, 238, 238

In the RGB color model, the red, green, and blue channels are balanced toward the cool end. The equal green and blue values are what give mint blue that distinctive soft aqua look.

For print work, use the CMYK values as a starting point, but always do a physical proof. Screen-to-print color shifts are real, especially with pale, low-saturation pastels like this one.

How Do You Create Mint Blue in Different Mediums?

Create mint blue by mixing blue and green in equal parts then adding white to lighten in paint, or by setting RGB values to approximately 174, 238, 238 in digital applications to get accurate color reproduction.

Acrylic Paint

Mix equal parts phthalo blue and cadmium green, then add titanium white gradually until you reach a pale, cool-toned pastel.

• Base colors: Phthalo blue, cadmium green (or viridian), titanium white
• Mixing ratio: 1 part blue + 1 part green + 4-6 parts white
• Process: Mix blue and green first to get a teal base, then lighten with white until the mint blue tone appears
• Common mistakes: Adding too much yellow-green shifts it toward seafoam; too much blue makes it look like pale sky blue
• Adjustment: If it looks too green, add a small amount of blue. If too warm, a touch more white usually fixes it.

Oil Paint

Use cerulean blue and viridian green as your base pigments, mixed 1:1 before lightening with lead white or titanium white.

• Pigments: Cerulean blue (PB35), viridian (PG18), titanium white (PW6)
• Technique: Oils blend slowly, so work the color on the palette before applying. The wet-on-wet method can muddy the hue.
• Drying note: Oils can shift slightly cooler or warmer as they dry. Test on a scrap surface first.

Watercolor

Layer cerulean blue with a diluted phthalo green wash on wet paper, building lightness through water ratio rather than added white pigment.

• Pigment selection: Cerulean blue (transparent), phthalo green (use sparingly – it’s strong)
• Dilution: High water-to-pigment ratio, 80% water or more for the pale mint effect
• Layering: Start with a pale cerulean wash, add a very light phthalo green glaze once dry

Gouache

Gouache handles mint blue well because of its opaque, flat finish. Mix cerulean blue with a small amount of viridian and white gouache.

Unlike watercolor, you can adjust lighter by adding more white pigment directly. The color stays true when dry, which makes it reliable for flat design work and illustration.

Print / CMYK

• Cyan: 27%
• Magenta: 0%
• Yellow: 0%
• Black: 7%
• Printing considerations: Coated paper retains the soft coolness better. Uncoated stock can make it look grayer.
• Pantone matching: Closest Pantone reference is PMS 2234 C or Pantone 290 C for lighter variants

For quick conversions between color systems, use an RGB to CMYK converter or an HSL to RGB converter when moving between digital and print workflows.

What Are the Best Practices for Using Mint Blue in Design?

Best practices for mint blue include pairing it with sufficient contrast, checking accessibility ratios, using it sparingly in text-heavy layouts, and anchoring it with a neutral to prevent the palette from feeling washed out.

Designers should test mint blue against both dark and light backgrounds, maintain WCAG contrast standards for any text overlaid on the color, and ensure the overall palette has enough tonal range to avoid flatness.

Use a color contrast checker before finalizing mint blue as a background in any UI or web context. Its lightness means dark text is almost always required for readable type.

Visual hierarchy can suffer if too much of a layout is covered in mint blue. The color reads as passive and calm, which is great for background use but tricky for focal elements.

In print design, remember that pale pastels can look significantly different on screen versus paper. Always proof before final production.

What Role Does Mint Blue Play in Branding and Marketing?

Mint blue plays a supporting yet distinct role in branding and marketing, communicating freshness, cleanliness, and gentle trust to consumers.

Marketing research indicates mint blue reduces perceived anxiety and encourages positive associations with health and clarity, making it effective for wellness, personal care, and tech brands seeking a calm, approachable identity.

It’s a smart choice for brands that want to feel modern without being cold or clinical. The color signals innovation without the aggression that bolder hues can carry.

Wellness apps, natural food brands, baby product lines, and eco-conscious packaging all use mint blue regularly. It also shows up in healthcare branding where trust and hygiene need to be communicated quickly.

A well-built brand guidelines document will usually define the exact hex, RGB, and CMYK values for mint blue to keep the color consistent across print, digital, and environmental applications. Inconsistency here is one of the most common brand problems I’ve seen, especially when teams hand off files between print vendors and web developers without a locked-down color reference.

For brands building a full visual identity, mint blue pairs well with a brand style guide that specifies how the color behaves across different surfaces and lighting conditions.
