OKLCH to HEX Converter

OKLCH in, HEX color code out — with the working shown.

To convert OKLCH to HEX, normalise the input, convert OKLCH back to RGB, write out the HEX value, then check the gamut. For example, oklch(61.82% 0.1935 258.33) in OKLCH is #2f81f7 in HEX.

This is a free OKLCH to HEX converter. Type or paste any OKLCH into the field above and the HEX value updates as you type, along with every other notation the web understands. HEX is a six-digit hexadecimal number, two digits per channel, written with a leading #.

Conversions run entirely in your browser using the same color engine as the rest of the site: values round-trip through linear sRGB and CIE XYZ rather than through an approximation, so what you copy is accurate to the last digit the format can carry.

How to convert OKLCH to HEX

  1. Normalise the input. Read the OKLCH value and scale each component into the 0–1 range the maths expects.
  2. Convert OKLCH back to RGB. OKLCH is not the display's native model, so the first move is always back to red, green and blue.
  3. Write out the HEX value. Convert back through sRGB and format the result as HEX.
  4. Check the gamut. Clamp anything that falls outside what an sRGB display can show, so the value you copy is the value you get.

Worked example: oklch(61.82% 0.1935 258.33) converts to #2f81f7. That color is Dodger Blue, and the tool above shows each intermediate step for whatever value you enter.
