Color Converter

Convert any color between HEX, RGB and HSL with live preview.

What Does the Color Converter Do?

This converter translates any color between the three formats used across web design — HEX, RGB and HSL — with a live preview swatch. Edit any of the three fields, or pick visually with the color picker, and the other formats update instantly. Shorthand hex (#f0c), bare RGB triplets (91, 91, 240) and full functional notation are all accepted.

How to Use the Converter

  1. Pick a color with the picker, or type into the HEX, RGB or HSL fields.
  2. All formats update in real time and the swatch shows the color.
  3. Copy whichever format your project needs with its Copy button.

When to Use Which Format

  • HEX (#5b5bf0) — the most compact and widely used format; the default for design tools, brand guides and CSS.
  • RGB (rgb(91, 91, 240)) — mirrors how screens mix light; the natural choice when you need alpha transparency via rgba() or when working with canvas and image data.
  • HSL (hsl(240, 83%, 65%)) — the human-friendly format: hue is the color wheel angle, saturation the intensity, lightness the brightness. Perfect for building palettes — keep hue fixed and vary lightness for consistent shades, or shift hue while keeping S/L for harmonious sets.

Developers use the converter to translate brand HEX codes into HSL for CSS custom-property theming; designers use it to fine-tune a color's lightness without eyeballing hex math.

Frequently Asked Questions

Are HEX, RGB and HSL the same color space?

Yes — all three describe exactly the same sRGB colors, just with different notation. HEX and RGB are byte values of red/green/blue; HSL re-maps those to hue, saturation and lightness. Conversion between them is lossless (within 8-bit rounding).

What is shorthand hex like #f0c?

A three-digit abbreviation where each digit doubles: #f0c equals #ff00cc. The converter accepts both forms and always outputs the full six-digit version.

Why does HSL make theming easier?

Because its axes match how people think about color: to darken a button hover state, reduce lightness by 10% — with HEX you would have to recompute all three channels. CSS variables plus HSL is a popular theming pattern.

How do I add transparency to a converted color?

Take the RGB output and switch to rgba(r, g, b, alpha), or the HSL output as hsla(…). An alpha of 0.5 is 50% transparent. Modern CSS also supports 8-digit hex (#5b5bf080).
