Color Mixing
Combine two colors using subtractive (pigment), additive (light), or weighted average models. See the result in hex, RGB, HSL, and CMYK—plus complementary and triadic harmony suggestions.
About This Calculator: Color Mixing
?Why It Matters
Designers, painters, and developers need to predict color outcomes. Physical mixing differs from digital—this tool helps bridge the gap.
⚙How It Works
We apply subtractive (multiply), additive (screen blend), or weighted average to your hex colors. Output formats and harmony suggestions follow standard color theory.
📖What You'll Learn
- Subtractive = paint, print, ink
- Additive = screens, light, overlays

Color mixing follows two main models: subtractive (pigments, paint, ink) and additive (light, screens). Subtractive mixing absorbs light—mixing colors darkens the result. Additive mixing adds light—red, green, and blue combine to white. This calculator simulates both for design, painting, and digital workflows.

Key Takeaways
- • Subtractive = pigments; additive = light. Use the right model for your medium.
- • Complementary colors (180° apart) create maximum contrast and vibrancy.
- • Triadic colors (120° apart) form balanced, harmonious palettes.
- • CMYK is for print; RGB/HSL for screens. Conversion is approximate.
Did You Know?
How Does Color Mixing Work?
Subtractive (Pigment)
Pigments absorb light. Mixing multiplies absorption—each color blocks more wavelengths. We simulate this by multiplying normalized RGB values. Result darkens toward black.
Additive (Light)
Screens emit light. Red + Green + Blue = White. Screen blend: result = 255 - (255-c1)*(255-c2)/255 per channel. Overlapping light adds brightness.
Weighted Average
Simple linear blend: result = ratio × color1 + (1-ratio) × color2. Useful for gradients and digital design when you want predictable interpolation.
Expert Tips
Mixing Models Compared
| Model | Use Case | Result |
|---|---|---|
| Subtractive | Paint, ink, print | Darkens (multiply) |
| Additive | Screens, light, overlays | Brightens (screen) |
| Weighted | Gradients, UI | Linear blend |
Frequently Asked Questions
What is the difference between subtractive and additive color mixing?
Subtractive mixing (pigments, paint, ink) absorbs light—mixing colors darkens the result. Additive mixing (screens, light) adds light—mixing red, green, and blue produces white. Paint uses subtractive; monitors use additive.
What is CMYK and when is it used?
CMYK (Cyan, Magenta, Yellow, Key/Black) is the subtractive color model for print. Printers layer ink to absorb light. Use CMYK for print-ready designs; RGB for screens. Converting RGB to CMYK can shift colors.
How does RGB additive mixing work?
RGB adds light. Red + Green = Yellow, Red + Blue = Magenta, Green + Blue = Cyan. All three at full = White. Screen blend mode approximates this: result = 255 - (255-c1)*(255-c2)/255 per channel.
What is color theory and the color wheel?
Color theory organizes colors by relationships. Complementary colors sit opposite on the wheel (e.g., red & cyan). Triadic colors are 120° apart. Analogous colors are adjacent. These relationships create harmony or contrast.
What are complementary colors?
Complementary colors are opposite on the color wheel. Red complements cyan, green complements magenta, blue complements yellow. They create maximum contrast and can make each other appear more vivid when placed side by side.
Why does pigment mixing differ from digital mixing?
Physical pigments absorb and reflect light differently than screen pixels emit it. Real paint mixing is subtractive and depends on pigment chemistry. Digital mixing is mathematical—subtractive simulation multiplies RGB; additive adds light.
