CMYK to Colortone – Name a Print Color
Enter cyan, magenta, yellow, and black percentages and see which CSS color name comes closest. cmyk(0%, 40%, 100%, 5%) – a typical packaging orange – matches DarkOrange with a ΔE of 4.06, and the tool lists five more candidates such as Orange and SandyBrown.
ΔE on the press floor
If you have ever attended a press check, you have met ΔE already. Printers measure color bars and proofs against a target and report the gap as a Delta E value. Many print buyers accept a ΔE (CIEDE2000) of about 2 to 3 for brand colors, while anything above 5 is usually visible to customers. This tool uses the same CIEDE2000 formula, but instead of comparing a proof with a target it compares your CMYK color with every named color and ranks the results:
| ΔE | Press-room reading |
|---|---|
| under 2 | matches – sign off |
| 2 – 5 | close – acceptable for most jobs |
| 5 – 10 | visible shift – similar family |
| over 10 | different color, same general hue at best |
Worked example
A teal-leaning ink build, cmyk(60%, 0%, 20%, 30%) (screen HEX #47B38F), gives MediumSeaGreen (ΔE 7.30), MediumAquaMarine (ΔE 7.42), and LightSeaGreen (ΔE 9.74). Two names within 0.12 of each other tells you the color sits between green and aqua – a useful hint when you brief a web team to "use something between sea green and aquamarine".
Where this helps
- Writing a style guide that lists print and web colors side by side.
- Briefing developers who need a starting point before they get exact hex values.
- Labeling swatches in InDesign or Illustrator with readable names.
For an exact web code, convert the same value with CMYK to HEX. To go the other way, look up a name's ink mix with Colortone to CMYK.
Frequently Asked Questions
Why convert a CMYK value to a color name?
Print specs are hard to talk about. A name like DarkOrange gives clients, copywriters, and developers a shared word for a color that is otherwise just four ink percentages.
Is ΔE the same measure printers use?
Yes, the idea is the same. Print shops measure proofs with a spectrophotometer and report the difference from the target as ΔE, often using CIEDE2000. This tool applies the same formula to compare your color with named screen colors.
Does the result depend on my paper or ICC profile?
No. The CMYK value is converted to RGB with the standard profile-free formula before matching. On a real press the printed color can shift, so check a proof for critical brand colors.
What CMYK input formats work?
cmyk(0%, 40%, 100%, 5%), 0, 40, 100, 5, or 0 40 100 5. Each channel is a percentage from 0 to 100.
