What this tool does
Enter a valid HEX, RGB or HSL color and convert it into the other common CSS formats. A live preview helps catch typing mistakes before copying values into a design system or stylesheet.
HEX, RGB and HSL are different ways to describe colors used on the web. They can represent the same visible color, although rounding during conversion may change the written values slightly. Accessibility depends on contrast between foreground and background, not on a color format by itself.
Useful for
- Translate design values between CSS formats.
- Inspect a color before adding it to a stylesheet.
- Create HSL values that are easier to adjust by hue, saturation or lightness.
How to use it
- Choose the input format or let the tool detect it.
- Enter the color value.
- Review the live swatch and converted formats.
- Copy the format required by your design or codebase.
Practical tips
- Check text/background contrast separately for accessibility.
- Use a shared design token rather than scattering slightly different values throughout a project.
- HSL can be convenient when creating systematic lightness variations.
- Color appearance varies across screens and display profiles.
