The Blue Green Color Code: HEX, RGB, CMYK

Blue green color is a cool secondary-adjacent color that sits at exactly 180 degrees on the color wheel, combining equal parts blue and green into a balanced, neutral-cool tone with RGB values of (0, 128, 128).

It shares visual territory with teal, cyan, and turquoise, yet each of those sits at a different point on the spectrum. Blue green is the anchor in the middle.

You will find it in nature constantly: shallow ocean water, tropical reef ecosystems, weathered copper. That natural familiarity is part of why it reads as calm and trustworthy across design, fashion, and branding contexts.

This guide covers everything from hue values and shades to color psychology, mixing methods, and real-world design applications.

Blue Green Color Codes

Blue green sits at hue 180 degrees on the color wheel, equal parts cyan and neither fully blue nor fully green. It is a cool-toned, secondary-adjacent color that reads differently depending on saturation and lightness.

• HEX: #008080
• RGB: R: 0, G: 128, B: 128
• CMYK: C: 100%, M: 0%, Y: 0%, K: 50%
• HSL: 180deg, 100%, 25%

In the RGB color model, blue green carries zero red and equal green and blue values. That balance is what gives it its distinctly neutral, cool character.

When working with print, the CMYK values shift noticeably compared to screen. Always do a test print first. Colors this saturated tend to look darker on coated stock than on screen.

Need to convert values quickly? A RGB to HEX converter or a HEX to RGB converter will save you time. If you are working across print and screen, an RGB to CMYK converter handles the translation.

For Pantone matching, the closest PMS equivalents are Pantone 326 C and Pantone 3275 C depending on the shade. Check against physical swatches before committing to a print run.

How Does Blue Green Differ From Similar Cool Colors?

Blue green differs from turquoise (warmer, more vivid), cyan (lighter, more electric), aquamarine (softer, more pastel), and teal (slightly greener) through its precise equal balance of blue and green values at mid-range lightness.

How Do You Create Blue Green in Different Mediums?

Create blue green by mixing equal parts blue and green paint, setting RGB values to (0, 128, 128) in digital applications, or using 100% cyan and 50% black in CMYK for print.

Acrylic Paint

Mix cobalt blue or phthalo blue with viridian or phthalo green in roughly equal parts. Start with blue as the base.

Add small amounts of green gradually and test on paper. Too much green shifts it toward jade. Add a touch of titanium white to raise lightness without changing the hue much.

• Base colors: Cobalt blue + Phthalo green (or Viridian)
• Ratio: 1:1 as a starting point, adjust to taste
• Common mistake: Adding too much yellow-green, which pulls it away from the neutral 180-degree hue
• Adjustment: Too green? Add more blue. Too light? Skip white and use less water

Oil Paint

Use Prussian blue or cerulean combined with viridian. Oil pigments are more saturated than acrylics, so use less than you think you need.

Note that oil colors shift slightly as they dry. Test a swatch and let it cure for a few days before committing to a large area.

• Pigments: Prussian blue (PB27) + Viridian (PG18)
• Drying shift: Colors typically deepen slightly as oil paint dries

Watercolor

Layer transparent phthalo blue over a dry phthalo green wash, or mix them wet-on-wet for a softer blend. Watercolor sits more toward the cyan family when diluted heavily.

Keep pigment-to-water ratio around 1:3 for a mid-tone blue green. More water gives you a near-pastel aqua.

• Pigment selection: Phthalo blue (PB15) + Phthalo green (PG7) – both transparent
• Layering tip: Let each layer dry completely before adding the next

Gouache

Gouache behaves similarly to watercolor when wet but dries opaque. Mix cerulean blue with permanent green light. Because gouache is opaque, you can add white directly to control lightness without losing color density.

Dried gouache can shift lighter than the wet mix. Always do a test patch first.

Print / CMYK

• Cyan: 100%
• Magenta: 0%
• Yellow: 0%
• Black: 50%
• Printing considerations: Coated stock will give a deeper, more saturated result; uncoated paper will produce a softer, slightly muted blue green
• Pantone matching: Pantone 326 C (lighter), Pantone 3285 C (darker/richer)

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

Best practices for blue green include applying it at high saturation sparingly, pairing it with warm neutrals for balance, checking contrast ratios against text, and using it consistently across touchpoints in branding contexts.

Designers should test blue green under different light sources, avoid placing it against pure white backgrounds where it can look cold, and ensure text placed on blue green meets WCAG AA contrast standards at minimum.

In web design, the full-strength #008080 value often needs to be lightened for backgrounds. Use a muted or light version for large areas and reserve the saturated version for interactive elements, calls to action, or icon color.

In print design, watch for color shifts between screen and paper. The CMYK version always looks slightly different from the RGB version, and the gap is noticeable with this color specifically. Run a proof first.

Use a color contrast checker to confirm legibility before finalizing any design with blue green as a background or text color.

What Role Does Blue Green Play in Branding and Marketing?

Blue green plays a dual role in branding and marketing, communicating trust, calm, and environmental awareness to consumers. Research indicates blue green reduces perceived anxiety in viewers, making it well-suited for healthcare, wellness, technology, and sustainability-focused brands seeking a credible, approachable identity.

It shows up in fintech, health apps, eco-product companies, and spa brands for a reason. It sits in a space that feels both professional and natural.

The color works across a logo, web UI, and packaging without requiring heavy modification between contexts. That cross-medium consistency is genuinely useful when building a visual identity.

Keep in mind that lighter, more aqua versions of blue green read as fresh and modern, while darker, muted versions skew more premium and serious. Choosing the right shade depends on what the brand needs to say, not just which shade looks nice in isolation.

For deeper reading on how this color fits into broader design systems, the fundamentals of color theory and color psychology are solid starting points.
