About This Tool

The color converter is a tool that helps designers and developers convert between different color formats. In web development and design work, we often need to switch between HEX (hexadecimal), RGB (Red Green Blue), and HSL (Hue, Saturation, Lightness) formats. This tool provides a visual color picker with real-time preview and instant conversion between three formats, all calculated locally in your browser.

How to Use

  1. Use the color picker to click and select your desired color, or directly enter a known color value
  2. Enter a hexadecimal color code in the HEX input field (e.g., #3B82F6)
  3. Or enter Red (R), Green (G), Blue (B) channel values (0-255) in the RGB section
  4. Or enter Hue (H 0-360), Saturation (S 0-100%), Lightness (L 0-100%) in the HSL section
  5. Changing any format value will automatically sync the other formats
  6. Click the 'Copy' button next to each format to copy the color code to clipboard

Common Use Cases

  • Web design: Convert design draft color values to CSS code format
  • Brand design: Convert brand color values between different design software
  • UI development: Generate various format color codes according to design specifications
  • Color adjustment: Use HSL to adjust color saturation and lightness
  • Learning: Understand relationships between different color models
  • Print preparation: Prepare corresponding format color values for different output media

FAQ

Q1: What's the difference between HEX, RGB, and HSL?

HEX is a hexadecimal color notation using 6 characters to represent color, like #FF5733. RGB represents color by mixing Red (R), Green (G), and Blue (B) channel values (0-255). HSL describes color through Hue (H), Saturation (S), and Lightness (L), which is closer to human color perception.

Q2: Which color format should I use in CSS?

All three formats can be used in CSS. HEX is the most compact and commonly used; RGB is suitable for scenarios requiring dynamic adjustment or transparency (RGBA); HSL is more intuitive when adjusting color depth or creating color variations.

Q3: Why doesn't my entered color value work?

Please check if the input format is correct: HEX should start with # followed by 6 hexadecimal characters; RGB channel values should be between 0-255; HSL's H should be between 0-360, S and L between 0-100. Make sure there are no extra spaces or characters.

Q4: How do I get a lighter/darker variant of a color?

Using HSL format is most convenient. Keep H (hue) and S (saturation) unchanged, increase L (lightness) to get a lighter variant, decrease L to get a darker variant. This is a common technique for creating color schemes.

Q5: Does this tool support transparency (Alpha)?

Currently this tool focuses on opaque color format conversion. For colors with transparency (like RGBA, HSLA), you can manually add the Alpha channel value after conversion. Future versions may add transparency support.
