Color Converter

What is a Color Converter?

A color converter translates color values between different representation formats used in web development and design. CSS supports multiple color notations — HEX for concise stylesheet declarations, RGB for programmatic color manipulation, and HSL for intuitive adjustments to hue, saturation, and lightness. This tool converts between all three formats in real-time with a live visual preview, so you always know exactly what color you're working with.

How to Use This Tool

1. Enter a color value in any supported format: HEX (#3b82f6), RGB (59, 130, 246), or HSL (217, 91%, 60%).
2. All other formats update automatically along with the color preview swatch, showing you the exact color.
3. Use the native color picker to visually select any color and get all format values instantly.

Common Use Cases for Developers

• Design-to-code handoff: Convert Figma/Sketch HEX values to RGB or HSL for CSS custom properties and theme systems.
• Creating color palettes: Use HSL to generate consistent shade variations by adjusting lightness while keeping hue and saturation constant.
• Canvas and WebGL: Convert HEX design tokens to RGB values needed for ctx.fillStyle or shader uniforms.
• Accessibility testing: Compare RGB values to calculate contrast ratios for WCAG compliance checks.
• CSS theming: Convert brand colors into HSL for easy dark/light mode variations using CSS custom properties.

Tips & FAQ

• When to use HSL: HSL is most intuitive for creating related colors. To darken a color, decrease lightness. To desaturate, decrease saturation. The hue stays constant so colors remain "in family."
• HEX shorthand: Three-character HEX codes like #f00 expand to #ff0000. This tool outputs the full 6-character format for clarity.
• CSS modern syntax: Modern CSS supports hsl(217 91% 60%) without commas and with optional alpha: hsl(217 91% 60% / 0.5).
