HEX to CMYK Colour Converter
Convert a HEX colour code straight into approximate CMYK print percentages, with each calculation stage shown along the way. Built for artists and creators planning printable artwork.

CMYK Result
C 40.3%, M 0%, Y 28.2%, K 51.4%
HEX: #4A7C59 RGB: rgb(74, 124, 89)
Calculation Stages
Stage 1 — HEX to RGB: #4A7C59 = rgb(74, 124, 89)
Stage 2 — RGB to CMYK: rgb(74, 124, 89) = C 40.3%, M 0%, Y 28.2%, K 51.4%
This result is a general mathematical estimate, not a press-ready or ICC-profile print value. Always confirm important colours with a test print.
How to Use the HEX to CMYK Converter
- Type or paste a HEX colour code into the field, with or without the # symbol.
- The tool first converts your HEX code to RGB, then converts that RGB value to approximate CMYK percentages — both stages are shown.
- Select Copy CMYK, Copy HEX or Copy RGB to copy the value you need.
- Select Random Colour to explore a new colour, or Reset to return to the default swatch.
How the HEX to CMYK Calculation Works
This tool combines two conversions:
- HEX to RGB: each pair of hexadecimal characters becomes a Red, Green or Blue value from 0 to 255.
- RGB to CMYK: K = 1 minus the largest of the three RGB proportions; C, M and Y are then calculated from the remaining proportions and K.
Worked example: #4A7C59 converts to rgb(74, 124, 89), which converts to approximately C 40.3%, M 0%, Y 28.2%, K 51.4%.
This is a general mathematical conversion, not a press-ready or ICC colour-profile value. Printed results vary by printer, ink, paper and colour profile — always confirm important colours with a test print.
Why Artists and Creators Use HEX to CMYK Conversion
If you have designed something using HEX colours — an illustration, a printable pattern, packaging artwork or an instruction sheet — this tool gives you a quick early estimate of the CMYK values a printer might use, without needing separate conversion steps. It is especially useful for artists moving between web-based design tools and print-focused software.
For guidance on mixing an equivalent colour in real paint rather than commercial ink, see the Paint Colour Mixer.

Frequently Asked Questions
What does this tool do?
It converts a HEX colour code directly into approximate CMYK print percentages, showing the RGB conversion step in between.
Does this tool accept 3-character HEX codes?
Yes. A shorthand code like #4A7 is automatically expanded to its full six-character version before converting.
Is the CMYK result press-ready?
No. This is a general mathematical estimate, not a press-ready or ICC colour-profile value. Always confirm important colours with your printer and a test print.
Why does the tool show two calculation stages?
HEX cannot convert directly to CMYK — it first becomes RGB, then RGB is converted to CMYK. Showing both stages makes the maths transparent.
Can I use this tool to match a Pantone colour?
No. Pantone is a proprietary, licensed colour matching system and is not included in this free tool.
Why might my printed colour look different from the CMYK shown here?
Actual print results depend on your printer, ink set, paper type and colour profile, none of which this general calculation can account for.
Can I use this for packaging or label design?
Yes, as an early planning estimate. Confirm final colours with your printer’s proofing process before a production run.
Do I need to include the # symbol?
No. You can enter the HEX code with or without the # symbol.
Can I use this tool to choose paint colours?
Yes, as a rough reference. The Paint Colour Mixer can help translate a digital colour into a physical paint mixing guide.
Is my colour data stored or sent anywhere?
No. All conversion happens directly in your browser. Nothing you enter is sent to a server or stored.
Can I use this tool on my phone?
Yes. The tool is designed to work on mobile, tablet and desktop screens.
Why is K sometimes high for dark, muted colours?
The K (black) channel absorbs most of the darkness in a colour, so darker or more muted HEX codes often produce a higher K percentage.
Can I copy all three values at once?
Use the individual Copy CMYK, Copy HEX and Copy RGB buttons to copy each value separately to your clipboard.
