Color Converter
Convert opaque CSS colors to HEX, RGB, HSL, HSV and CMYK
Enter a color value and inspect HEX, RGB, HSL, and more first; advanced formats and scenarios are available in Advanced mode.
The full guide also includes pitfalls, worked examples, snippets, FAQs, and related tools for checking results or troubleshooting.
About this tool
Convert opaque CSS colors from HEX, RGB, HSL or names into HEX, RGB, RGBA with alpha 1, HSL, HSV and approximate CMYK. A native picker and CSS custom property output help with frontend handoff. This tool does not preserve transparency or manage print color profiles.
Scenario Recipes
Convert an opaque CSS named color
Goal: Create frontend color references from a supported CSS input.
- Enter rebeccapurple and run Convert color.
- Confirm HEX is #663399.
- Open Advanced to inspect approximate CMYK and the CSS variable snippet.
Result: HSV and CMYK are outputs; they are not accepted as source color syntax.
Failure Clinic (Common Pitfalls)
Transparency and print profiles need another workflow
Cause: This converter rejects semi-transparent input and calculates unprofiled CMYK estimates.
Fix: Keep alpha-aware source values in a suitable converter and use the printer’s requested ICC workflow.

Which formats can I enter?
Enter an opaque HEX, RGB, HSL, or CSS named color such as rebeccapurple. The browser must normalize it to a six-digit RGB hex value. HSV and CMYK are output formats only; transparent colors, currentColor, CSS variables, and wide-gamut inputs are not supported here.
Does RGBA output preserve transparency?
The converter accepts opaque colors and emits alpha 1 in RGBA. It rejects semi-transparent input instead of discarding alpha. Use a converter with alpha support when the original design depends on transparency.
Can the CMYK result be sent directly to a printer?
It is an approximate channel conversion from RGB, without ICC profiles, paper, ink, or press settings. Use the printer’s required color workflow for print-ready assets. HSL/HSV/CMYK percentages are rounded, so repeated conversions can also introduce small changes.
