Color Converter Guide
How to convert HEX, RGB, and HSL color values for CSS variables, design tokens, documentation, and contrast checks.
Quick answer
Paste a color value and copy the equivalent HEX, RGB, or HSL representation. Use the converted value in CSS, design docs, tokens, or contrast checks.
What this tool does
The color converter translates between common color formats so the same color can be used in different parts of a design or development workflow.
Step-by-step use
- Paste the source color
- Review the generated formats
- Copy the format your project needs
- Check opacity or alpha usage separately when relevant
- Test actual foreground/background pairs when the color is used for text
Data handling and processing behavior
Color conversion is handled in the browser for this tool. Avoid entering sensitive unreleased brand values unless you have reviewed the implementation.
Best inputs
- HEX values
- RGB values
- HSL values
- Design token colors
- Colors sampled from screenshots or assets
Examples
CSS token
Convert #10b981 into RGB channels when your CSS system uses alpha-friendly custom properties.
Palette review
Convert a HEX value to HSL when adjusting lightness or saturation is easier than editing RGB numbers.
Assumptions and limits
- Conversion does not decide whether a color pair is readable
- Conversion does not create a full palette
- HSL changes may not match perceived brightness perfectly
- Project naming and semantic token choices still need human review
Common mistakes
Skipping contrast checks
Converted colors still need to be tested in actual UI pairs.
Mixing syntax conventions
Make sure your project expects comma-separated or modern space-separated RGB/HSL syntax before copying.
