How Color Converter works

  1. Type or paste a color value — HEX (#3b82f6), rgb(), hsl(), or a CSS color name like 'cornflowerblue'.
  2. Or click the color swatch to open the native color picker and select visually.
  3. View the converted values in HEX, RGB, HSL, HSV, and CMYK simultaneously.
  4. Click the copy button next to any format to copy that specific value.
  • Convert a designer's HEX color to RGB or HSL for use in CSS variables.
  • Find the CMYK equivalent of a brand color for a print document.
  • Translate a CSS color name into its HEX code for a design tool.
  • Adjust a color's lightness in HSL while keeping the same hue and saturation.
  • Quickly preview what a color looks like before using it in a design.

All color parsing and conversion happens locally in your browser. No color values are sent to a server.

  • Alpha/transparency values are not included in the conversion.
  • CMYK values are mathematical approximations, not calibrated to a specific printer profile.
  • Only standard CSS-recognized color formats and names are accepted as input.

Color Converter

Color Converter accepts any color input — HEX, rgb(), hsl(), or CSS color name — and converts it to all five common formats: HEX, RGB, HSL, HSV, and CMYK. A large color swatch preview updates live, and a color picker syncs with the text input.

FAQ

Frequently asked questions

How are CSS color names parsed?

CSS named colors (like 'red', 'cornflowerblue', 'papayawhip') are parsed by drawing them onto a 1×1 canvas and reading back the RGB pixel value — the browser handles the name-to-RGB mapping.

Is CMYK useful for web work?

CMYK is primarily a print color model, included for workflows where colors are specified for print and need to be adapted for screen. RGB-to-CMYK conversions are approximate since the color spaces don't map perfectly.

What's the difference between HSL and HSV?

Both describe color using Hue, Saturation, and a third channel — Lightness (HSL) or Value/Brightness (HSV). HSL is common in CSS, while HSV is common in design and image-editing tools like color pickers.

Can I paste a color with alpha/transparency (e.g. rgba or #RRGGBBAA)?

The tool focuses on opaque color conversion across HEX, RGB, HSL, HSV, and CMYK. Alpha channel values are not part of the conversion output.

Why does my CMYK output look different from my design software?

CMYK conversion from RGB is a mathematical approximation. Professional print software uses ICC color profiles calibrated to specific printers and inks, which can produce different CMYK values for the same RGB color.

How precise are the converted values?

RGB and HEX conversions are exact. HSL, HSV, and CMYK values are rounded to practical precision (typically whole numbers or one decimal place) for readability.

Can I use the color picker to find a color visually?

Yes — the native color picker lets you visually select a color, and all five format outputs update instantly to match your selection.
