What is Color Mixer?
Color Mixer is an online tool that blends two or more colors at your desired ratios to create new colors. You can mix up to 5 colors simultaneously and fine-tune each color’s ratio using sliders. Using RGB additive mixing, it provides accurate color blending results optimized for digital environments.
It’s useful for web design, UI/UX work, brand color development, and many other fields. You can instantly view and copy the HEX code and RGB values of mixed colors for immediate use in your projects. With gradient preview, intermediate color generation, and color harmony recommendations, you can achieve more creative color work.
When to Use This Tool
- Brand Color Development – Create secondary or accent colors based on existing brand colors, building a cohesive color palette.
- UI/UX Design – Generate variations like button hover states and disabled states from base colors with precise mixing ratios.
- Web Development – Preview how intermediate colors will look before creating CSS gradients, and find harmonious color combinations.
- Illustration – When you need natural transition colors between two colors, use the intermediate color feature to create smooth color spectrums.
- Interior Design – Digitally simulate paint and accessory colors to predict the result of mixing two colors.
- Color Theory Learning – Visually understand the principles of color mixing and experiment with complementary, analogous, triadic, and other color harmony theories.
Key Features
- Multi-Color Mixing – Mix from 2 to 5 colors simultaneously. Freely adjust the number of colors for everything from simple two-color blends to complex multi-color mixes.
- Ratio Adjustment Sliders – Precisely adjust each color’s mixing ratio from 0% to 100% using sliders. Results update in real-time, making it easy to find your desired color.
- Gradient Preview – See how the colors used in mixing flow naturally together as a gradient. Great reference for CSS gradient work.
- Intermediate Color Generation – Choose from 3 to 9 steps to automatically generate intermediate colors up to the mixed result. Useful for expanding color palettes or creating smooth transitions.
- Color Harmony Recommendations – Based on the mixed result color, get recommended colors based on color harmony theory: complementary, analogous, triadic, and split-complementary.
- Mix History – Previously created mix results are automatically saved. Convenient for finding or comparing colors you liked.
- One-Click Copy – Copy HEX codes or RGB values to your clipboard with a single click for immediate use in your projects.
How to Use
- Select Number of Colors – Use the dropdown at the top to select how many colors to mix (2-5). The default is set to 3 colors.
- Enter Colors – Click each color picker to select a color, or enter color codes directly in the HEX input field. You can also use the “Random Color” button to generate random colors.
- Adjust Ratios – Move the slider below each color to adjust the mixing ratio. The mix result updates in real-time as ratios change.
- Check Results – View the final color and HEX/RGB codes in the Mix Result section. Use the copy button to save codes to your clipboard.
- Use Additional Features – Check color flow with the gradient preview, adjust intermediate color steps to find needed colors, and explore harmonious color combinations in the Color Harmony tabs.
Color Mixing Principles
What is RGB Additive Mixing?
RGB Additive Color Mixing creates new colors by adding the three primary colors of light: Red, Green, and Blue. This is the color mixing method used in light-emitting devices like digital screens, monitors, and TVs.
- Red + Green = Yellow
- Green + Blue = Cyan
- Blue + Red = Magenta
- Red + Green + Blue = White
Unlike subtractive mixing used when mixing paints or inks (where colors get darker when combined), additive mixing gets brighter as colors are added. This tool uses RGB additive mixing to provide accurate color blending results optimized for digital environments.
Weighted Average Calculation
When mixing multiple colors, the average is calculated by applying ratios (weights) to each color’s RGB values. For example, mixing red (#FF0000) and blue (#0000FF) at a 50:50 ratio:
- R = (255 × 0.5) + (0 × 0.5) = 127
- G = (0 × 0.5) + (0 × 0.5) = 0
- B = (0 × 0.5) + (255 × 0.5) = 127
- Result: RGB(127, 0, 127) = #7F007F (Purple)
Color Harmony Theory
Color Harmony is the theory of creating visually pleasing and balanced color combinations. Based on positional relationships on the Color Wheel, there are several harmony types.
Complementary
Two colors positioned directly opposite (180°) on the color wheel. They create the strongest contrast effect, making each color stand out. Examples: Red and Cyan, Yellow and Purple. Often used for designs that need to grab attention.
Analogous
Colors adjacent to each other (about 30° apart) on the color wheel. A harmonious combination commonly found in nature, providing a soft, comfortable feel. Examples: Red-Orange-Yellow, Blue-Cyan-Green. Suitable for unified designs.
Triadic
Three colors forming an equilateral triangle (120° apart) on the color wheel. Creates a diverse yet balanced color combination. Examples: Red-Yellow-Blue, Orange-Green-Purple. Used for designs that are vibrant yet stable.
Split-Complementary
Uses the base color and the two colors adjacent to its complement (at 150° and 210°). Maintains the intensity of complementary harmony while allowing more diverse colors. An approach that makes it easy even for beginners to create harmonious palettes.
Frequently Asked Questions
Why do RGB mixing and paint mixing produce different results?
RGB mixing is additive mixing that adds light, while paint mixing is subtractive mixing that absorbs light. In additive mixing, colors get brighter as they’re combined, and mixing all colors produces white. In subtractive mixing, colors get darker as they’re combined, and mixing all colors approaches black. This tool uses RGB additive mixing appropriate for digital environments.
How is the mixing ratio calculated?
Each color’s slider value is used as its weight. For example, if color A is 60% and color B is 40%, the final RGB value is calculated for each channel as (A value × 0.6) + (B value × 0.4). If all ratios are 0%, they are distributed equally.
What criteria are used for color harmony recommendations?
The mixed result color is converted to HSL (Hue-Saturation-Lightness) color space, then harmonious colors are calculated based on angular relationships on the color wheel. Complementary colors are at 180° opposite, analogous colors are at ±30° adjacent positions, triadic colors are at 120° intervals, and split-complementary colors are at 150°/210° positions.
Where is the mix history stored?
Mix history is stored in your browser’s localStorage. Previous records are maintained when you visit again using the same browser. History is reset if you delete browser data or use incognito mode.
How are intermediate colors calculated?
Intermediate colors are generated using Linear Interpolation from the first input color to the mixed result color. RGB values for each channel are divided equally according to the selected number of steps to create natural color transitions.
Can I use this on mobile?
Yes, it works perfectly on mobile devices. Built with responsive design, color selection and ratio adjustment work via touch on smartphones and tablets. Use it directly in your web browser without installing any apps.
