What Is a Color Converter?
A color converter translates color values between different notation systems used in web development and design. The three most common formats are HEX (hexadecimal like #3b82f6), RGB (red-green-blue components like rgb(59, 130, 246)), and HSL (hue-saturation-lightness like hsl(217, 91%, 60%)). This tool lets you input a color in any supported format—or pick one visually—and instantly see the equivalent values in all formats, along with individual RGB channel values.
How to Use the Color Converter
- Click the color picker swatch to visually select a color, or type a color value directly in the input field.
- Enter colors in HEX (#3b82f6), RGB (rgb(59,130,246)), HSL (hsl(217,91%,60%)), or named CSS colors (blue, coral).
- View the large color preview swatch below the input.
- See the converted values in HEX, RGB, and HSL formats.
- Copy any format using the copy button next to each value.
- Check the individual R, G, B channel values at the bottom.
Common Use Cases

- Design Handoff — Translate color values from design specifications (Figma, Sketch) into the exact format your codebase requires.
- Accessibility Testing — Extract precise color values to check contrast ratios and ensure your color choices meet WCAG accessibility guidelines.
- Theme Customization — Convert brand colors into different formats when configuring CSS custom properties, Tailwind configs, or design tokens.
FAQ
What color formats are supported as input?
The tool accepts HEX values (#rgb, #rrggbb), RGB notation (rgb(r, g, b)), HSL notation (hsl(h, s%, l%)), and named CSS colors (red, cornflowerblue, etc.).
Why does the color picker only show HEX output?
The native HTML color picker works with HEX values. Once a color is selected, the tool automatically converts it to all supported formats (HEX, RGB, HSL) displayed below.
Does this support alpha/transparency?
Currently, the tool focuses on opaque colors. HEX with alpha (#rrggbbaa), RGBA, and HSLA input may be parsed but the alpha channel is not separately displayed.
Is the conversion accurate?
Yes. The tool uses the culori library, a high-precision color science library that handles color space conversions accurately according to CSS Color Level 4 specifications.
