This page opens the color converter with RGB preselected as the input format — enter rgb(59, 130, 246) or just the bare triplet 59, 130, 246 and run it to get the matching #rrggbb code.

HEX is the most compact and universal color notation: one #rrggbb token works in every CSS property, SVG attribute, design tool and brand style guide, which makes it the standard way to hand a color from a mockup to code.

Beyond this pair, the full tool also returns HSL and CMYK for the same input, offers a native color picker and previews the color on a swatch — all computed locally in your browser with nothing uploaded.

Accepted Formats & Rules

  • Converts between HEX, RGB, HSL and CMYK color models.
  • Native color picker that fills the value field in the selected format.
  • Live preview swatch plus one-click copy of all four notations.

Key Benefits

✓ One input, every notation: type a color once and read it back as HEX, RGB, HSL and CMYK simultaneously.
✓ Forgiving parser: accepts #fff, #3b82f6, rgb(255, 0, 0), bare "255, 0, 0" triplets and hsl(120, 50%, 50%) alike.
✓ Runs entirely in your browser — color values are never uploaded anywhere.

Use Cases

  • • Turn the #rrggbb code from a brand book into rgb() or hsl() notation before wiring hover and disabled states in CSS.
  • • Convert an on-screen RGB color to CMYK percentages to sanity-check how it will separate before sending business cards or flyers to print.
  • • Eyedrop a color with the built-in picker and copy all four notations at once for a design-to-code handoff.
