Understanding Color Formats

Digital colors can be represented in multiple formats, each with different advantages. This tool converts seamlessly between the three most common web color formats: HEX, RGB, and HSL. All processing happens in your browser—your color choices are never tracked or stored.

#️⃣ HEX (Hexadecimal)

Format: #RRGGBB (6 characters) or #RGB (3-character shorthand)
Example: #2563EB or #F00 (red)
Best for: CSS, HTML attributes, design tools. Most compact format for web development.

🔴🟢🔵 RGB (Red, Green, Blue)

Format: rgb(R, G, B) where each value is 0-255
Example: rgb(37, 99, 235)
Best for: CSS functions, JavaScript color manipulation, programmatic color generation. Easy to understand as light mixing.

🌈 HSL (Hue, Saturation, Lightness)

Format: hsl(H, S%, L%) where H is 0-360°, S and L are 0-100%
Example: hsl(221, 83%, 53%)
Best for: Creating color schemes, adjusting brightness/saturation. Most intuitive for human perception.

Common Use Cases

  • CSS Styling: Convert between formats for different CSS properties and browser compatibility
  • Design Handoff: Translate colors from design tools (often HEX) to code-friendly formats
  • Color Schemes: Use HSL to create variations (adjust lightness for hover states)
  • Accessibility: Calculate contrast ratios using RGB values
  • Brand Guidelines: Document colors in multiple formats for different use cases

Color Theory Quick Tips

Creating Hover States

Use HSL: decrease Lightness by 10-15% for darker hover effects, or increase for lighter ones. Much easier than calculating RGB changes.

Ensuring Contrast

For WCAG AA compliance, text needs 4.5:1 contrast ratio. HSL Lightness differences of 40%+ usually meet this requirement.

Frequently Asked Questions

Which format should I use in CSS?

All three work in modern browsers. HEX is most common and compact. Use RGB/HSL when you need transparency (rgba() or hsla()) or dynamic color manipulation.

What does the # in HEX mean?

The # symbol indicates a hexadecimal color value. It's required in CSS but often optional in design tools. The following 6 characters represent Red, Green, and Blue in base-16 (00-FF = 0-255).

How does HSL Hue work?

Hue is a degree on the color wheel: 0° = Red, 60° = Yellow, 120° = Green, 180° = Cyan, 240° = Blue, 300° = Magenta, 360° = back to Red. It makes selecting complementary colors (180° apart) intuitive.

Can I add transparency?

Yes! Use rgba(R, G, B, A) or hsla(H, S%, L%, A) where A is 0-1. Modern CSS also supports 8-character HEX: #RRGGBBAA.
