CMYK to HEX Converter

Convert CMYK percentages to an approximate HEX color for screens.

CMYK-to-screen conversion is approximate because print and display color systems differ.

What this tool does

CMYK to HEX produces a rough sRGB screen equivalent from four process-color percentages. The conversion is deterministic in this calculator but not color-managed for a specific print process.

Enter the values in the calculator above and choose Calculate. The calculation runs in your browser; the inputs are not intentionally sent to a Colormapped application server.

How it works

  1. Convert each CMYK percentage to a 0–1 fraction.
  2. Calculate approximate red, green, and blue channels after the black component.
  3. Round RGB to 8-bit integers.
  4. Encode the RGB result as a six-digit HEX value.

Worked example

Inputcmyk(62% 62% 0% 6%)
Output#5B5BF0

The simple formula returns RGB 91, 91, 240. That screen value is an approximation of the numeric CMYK input, not a measurement of printed color.

When to use it

  • Build a rough web preview from a CMYK reference.
  • Move print-oriented values into a mockup before profile-aware assets are available.
  • Understand how four simple percentages map into three screen channels.

Accuracy and limits

  • The conversion does not model ICC profiles or printer/paper behavior.
  • Two different real print setups can use the same CMYK percentages and still look different.
