Introduction
CSS `color-mix()` allows colors to be mixed directly in CSS. It is useful for design tokens, hover states, tinted backgrounds, and accessible color ramps.
This visualizer helps you experiment with mixes and generate fallbacks for browsers that do not yet support the feature.
How it works
The tool builds `color-mix()` values from your selected colors, percentage, and color space. It previews the result, generates CSS variables, and creates fallbacks using sRGB interpolation or browser-computed colors where available.
- The preview updates locally.
- Ramps are generated from 0% to 100%.
- CSS variables use duplicate declarations for fallback support.
- Unsupported color spaces are detected and flagged.
How to use
- Choose two colors.
- Set the mix percentage.
- Select a color space.
- Choose ramp steps.
- Copy the generated CSS variables.
Practical example
Generated CSS may look like this:
:root {
--mix-50: #0c8f84;
--mix-50: color-mix(in srgb, #0d9488 50%, #0f172a 50%);
}
Use cases
- Creating hover and active state colors.
- Building tinted backgrounds.
- Generating accessible color ramps.
- Testing wide-gamut color mixing.
- Creating design tokens.
Best practices
- Use fallbacks for browsers without `color-mix()` support.
- Check contrast after mixing colors.
- Use CSS variables for maintainable design tokens.
- Test wide-gamut color spaces in supporting browsers.
- Keep color ramps consistent across themes.
Common mistakes
- Assuming every browser supports every color space.
- Using mixed colors without checking contrast.
- Forgetting fallback declarations.
- Using too many ramp steps unnecessarily.
- Mixing colors without considering theme context.
Limitations
- Fallbacks are approximate for non-sRGB color spaces.
- Browser color management may affect preview accuracy.
- Wide-gamut displays may show colors differently.
- Contrast is not automatically calculated by this tool.
Browser compatibility
CSS `color-mix()` support varies by browser and color space. The tool detects support and generates fallbacks where possible.
FAQ
Are my colors uploaded?
No. All color processing happens locally in your browser.
Why generate a fallback?
Fallbacks help browsers that do not support `color-mix()` display a reasonable color instead of failing.
Which color space should I use?
Start with `srgb` for broad compatibility. Use `oklab` or `oklch` for perceptual mixing where supported.
Does this check contrast?
Not automatically. Use the Color Contrast Matrix Generator to check accessibility contrast.
