Mixing colors can feel like magic—especially when you combine two favorites like blue and green. Depending on how you mix them, you get teal, turquoise, seafoam, or a bright cyan glow. But what exactly happens when you put these two cool tones together?
In this article, you’ll learn how to mix blue and green in paint, light, and digital design, avoid muddy results, and create beautiful custom shades for your next project.
What Happens When You Mix Blue and Green?
When you mix blue and green, the result is usually a shade of cyan, teal, or turquoise—depending on how much of each color you use. These blue-green colors belong to the cool color family and often evoke feelings of calm, cleanliness, and nature.
Blue + Green in Different Mediums
In paint, mixing green and blue generally gives you teal (if you use more blue) or turquoise (if you use more green…(which itself is made from blue + yellow—learn how to mix green here)).
In light, combining blue and green produces cyan, one of the three primary colors in the RGB (red, green, blue) color model.
In digital design, blue-green shades range from #00FFFF (cyan) to #008080 (classic teal) and beyond.
Why the Mixing Ratio Matters
Quick Tip: The exact result depends on the medium (paint, light, digital) and your ratio. A 50/50 mix typically leans toward cyan in digital or turquoise in pigment.
Understanding Blue and Green in Color Theory
Mixing colors isn’t just about putting two paints on a palette. It’s based on color theory, which includes how colors behave when combined using different systems. To fully understand what happens when you mix blue and green, let’s explore a few fundamentals.
Primary and Secondary Colors in RYB
In the RYB (Red, Yellow, Blue) model, blue is a primary color. Green is a secondary color, created by mixing blue and yellow. So when you mix blue + green, you’re really combining a primary with a secondary color.
What Are Tertiary Colors Like Teal and Cyan?
In most pigment systems, this combination results in a tertiary color—like teal, cyan, or turquoise. These tertiary colors often live between blue and green on the color wheel, forming smooth transitions.

👉 Why Medium Matters: Pigment vs. Light vs. Digital
This is where most beginner artists get confused. Mixing blue and green doesn’t always give the same outcome because:
- Paint/pigment mixing (subtractive) absorbs light, and the mix depends on the pigments used.
- Light mixing (additive) blends different wavelengths to create new hues.
- Digital color uses hexadecimal (HEX) or RGB code systems, offering precision but no physical mixing.
Each medium has its own rules, which we’ll explore in depth and if you’re curious how blue shifts with red instead, explore what red and blue make
👉 Role of the Color Wheel
The color wheel helps you predict results. Blue and green sit right next to each other—called analogous colors—which means their mix will always stay in the cool family. They blend more harmoniously than opposites (like blue and orange), making them ideal for painting ocean scenes, foliage, and tranquil skies.
How to Mix Blue and Green Paint (Step-by-Step)
You don’t need to be a professional to create gorgeous blue-green colors. Here’s how to do it confidently:
👉 Tools and Materials You’ll Need:
- Primary blue paint (like phthalo or cobalt blue)
- Green paint (like viridian or permanent green)
- Palette or mixing tray
- Brush or palette knife
- White and black paint for light/dark adjustments
- Water (for watercolor) or medium (for acrylic/oil)
👉 Step-by-Step Instructions:
- Start with equal parts blue and green on your palette. Mix them slowly using a knife or brush.
- Observe the base color—it should lean toward cyan or turquoise.
- Adjust the tone:
- Add more blue to get a deeper teal.
- Add more green to brighten toward lime or seafoam.
- If it looks too dark or dull:
- Add a tiny bit of white to lighten and reveal undertones.
- Avoid overmixing—this can turn it muddy.
If your mix turns gray or brown, clean your tools and try again with cooler pigments.
Mixing Blue and Green in Paint
When it comes to physical paint, mixing blue and green doesn’t give you just one color—it gives you a range of rich, cool-toned hues. The exact shade depends on the type of paint, the proportions used, and even the pigment purity.
👉 What You Get: Teal, Turquoisem and Seafoam Color with Acrylic, Watercolor, or Oil
- Acrylic paint mixes cleanly if you’re using pure colors. Blue and green typically produce teal or turquoise, with slight variations based on opacity.
- Watercolor can yield softer, more transparent versions of blue-green shades, often resembling seafoam or mint if diluted with water.
- Oil paint blends slowly but beautifully. You can get deeper blue-greens that lean toward forest teal when using darker hues like phthalo blue or viridian green.
Pro Tip: Avoid mixing muddy colors by using cool-toned pigments—like phthalo blue and viridian green—instead of warmer ones like ultramarine or sap green.
👉 How to Mix Teal, Cyan, or Aqua on a Palette
- For teal: 2 parts blue + 1 part green
- For turquoise: 1 part blue + 2 parts green
- For cyan: Equal parts of both, using pure primary colors
👉 Why Do Blue and Green Sometimes Make a Muddy Color?
- Dirty tools: Leftover red, orange, or brown on your brush can dull the mix.
- Wrong pigments: Warm-toned or low-quality paints (like ultramarine or sap green) often clash or contain fillers.
- Overmixing: Mixing too much flattens the color, especially in watercolor.
- Too much white or black: These can desaturate your mix if added too early.
Mixing Specific Blue-Green Shades (Teal, Turquoise, Cyan)
To explore the stunning world of blue-green hues, here’s a quick guide on how to mix these unique shades using basic colors:
| Color Name | How to Make It (Paint Mixing) | Digital Note |
|---|---|---|
| Teal | Mix 2 parts blue + 1 part green. Add black slightly to deepen. | HEX: #008080 |
| Turquoise | Mix 1 part blue + 2 parts green. Add a bit of white for brightness. | HEX: #40E0D0 |
| Bondi Blue | Start with turquoise base → add more blue, and just a hint of gray to mute it slightly. | HEX: #0095B6 |
| Blue-Green Algae | Mix equal parts phthalo blue and sap green, then soften with a touch of white or yellow ochre. | HEX: #00A693 |
| Cerulean | Use cerulean blue directly from tube or mix cobalt blue + a touch of green. Optional: lighten with white. | HEX: #007BA7 |
| Celeste (Sky Blue) | Mix blue + green, then add lots of white until it’s pastel and airy. | HEX: #B2FFFF |
| Robin Egg Blue | Equal parts blue + green + white. You can also start with turquoise, then add white for softness. | HEX: #00CCCC |
| Peacock Blue | Mix deep blue (phthalo or Prussian) with a small amount of green and black to make it rich and dark. | HEX: #1F456E |
| Charleston Green | Mix teal with black (2:1 ratio) to produce a nearly black-green with blue undertones. | HEX: #232B2B |
| Electric Blue | Start with cyan, then boost brightness with a bit of white and a dash of green or violet depending on tone. | HEX: #7DF9FF |
| Pine Green | Use green as base, mix in a small amount of blue, and darken with black. | HEX: #01796F |
Mixing Blue and Green in Light
When mixing light, the rules flip. Unlike paint, light behaves additively, meaning colors combine by adding wavelengths, not absorbing them.
Additive Mixing in the RGB Model
Blue + Green = Cyan (In Light)
In the RGB color model, which is used in screens and stage lighting, blue and green light combine to make cyan—one of the three secondary colors in RGB, along with yellow and magenta.
Here’s what happens:
- Blue light wavelength: ~450–495 nm
- Green light wavelength: ~495–570 nm
- Resulting cyan light: ~480–500 nm, often appearing bright or neon-like
Cyan is often used in digital interfaces, underwater visuals, and medical displays due to its crisp, vibrant look.
Cyan in RGB vs. CMYK
While RGB is used for screens (light), CMYK is used for printing and works subtractively (like paint).
👉 In CMYK:
- Cyan is a base ink, so you don’t mix it from blue + green
- To make turquoise or bluish-green tones in print:
- Start with cyan
- Add yellow to shift toward green or turquoise
- Add black (K) to deepen the shade into teal
🎨 HEX Code Examples:
- Cyan:
#00FFFF - Teal:
#008080 - Turquoise:
#40E0D0
Exploring Shades Between Blue and Green
Mixing blue and green isn’t just about getting cyan—you can create a whole spectrum of blue-green shades, from deep teal to soft mint. It all depends on your ratios, pigments, and medium.
👉 Cyan vs. Teal vs. Turquoise: What’s the Difference?
These three names often get thrown around interchangeably, but they’re slightly different:
- Cyan: The purest blend of blue and green, used in RGB and CMYK models. It’s bright, light, and very vibrant.
- Teal: A darker blue-green that leans toward the blue side. It feels rich and earthy—often used in fashion and home decor.
- Turquoise: A mix between teal and cyan, often leaning toward green. It’s playful and tropical, like Caribbean water.

FAQs
Does blue and green make turquoise or cyan?
It depends on the ratios and medium. In paint, a 1:2 ratio of blue to green gives turquoise, while equal parts can lead to cyan. In digital color or light (RGB model), blue and green always mix to form pure cyan.
Why does my blue-green mix look muddy or gray?
You might be using warm-toned pigments (like ultramarine or sap green) or accidentally adding in complementary colors like red. Stick to cool hues like phthalo blue and viridian green, and make sure your tools are clean.
Is blue-green a warm or cool color?
Blue-green (including cyan, teal, and turquoise) is considered a cool color. It evokes feelings of calm, tranquility, and clarity—perfect for serene designs or nature-inspired art.
Can I make seafoam or mint by mixing blue and green?
Yes! Mix blue and green, then add white slowly until you reach the desired pastel tone. Seafoam has more green, while mint has a touch more blue and white.
Is blue-green a secondary or tertiary color?
In traditional RYB color theory, green is secondary (blue + yellow). So blue-green is a tertiary color, created by mixing a primary (blue) with a secondary (green).
Can I use food coloring to mix blue and green in baking or crafts?
Yes, and the same rule applies—equal parts blue and green make a cyan-like frosting. Adjust ratios to create pastel or jewel-toned icing. Just remember: food dyes are transparent, so the base (frosting or batter) may affect the result.
Can I mix blue and green to get emerald or jade green?
Yes—start with a deep green base, then add blue slowly until you reach the desired richness. Add a touch of black or gray for depth if needed. For jade, add a little white to soften it.
What is the best ratio to mix blue and green for teal?
The most common formula is 2 parts blue to 1 part green. Adjust to taste depending on how dark or saturated you want your teal.
How do I mix blue-green colors in watercolor?
Use transparent pigments like phthalo blue and viridian green. Mix gently on a wet palette and test on scrap paper. Add water to create soft seafoam or mint tones.
Can I mix blue and green with colored pencils or markers?
Not exactly. Instead of blending physically, layer the colors gently. Start with green, overlay blue lightly, and use a blending pencil or white to smooth the transition.
Can I make turquoise without green paint?
Yes. Mix blue + a small amount of yellow, then add white. The yellow creates green, which combines with blue to form turquoise. It may take a few tries to get the balance right.
