CMYK to NCS Converter

Here on this page we can do quick CMYK to NCS conversion. Just use the form below. It will take your CMYK input and process the numbers to work out the matching RGB in hexadecimal format. This tool then looks up the NCS color database to match the closest NCS color code for your input CMYK color code.

Enter CMYK color values

Important: This input form requires you to provide CMYK values in percentage from 0 to 100% for each color (Cyan, Magenta, Yellow, Black). This converter tool will only process values in integer (natural number) format.

How does this tool work?

It’s quite simple, since your CMYK code could be easily converted to RGB and hexadecimal values. The computer algorithm runs on the server’s side. It is designed to find close matches between two colors (CMYK and NCS in this case) so we use NCS reference chart which is pre-populated with hex values and then this tool picks a color which algorithm considers to be the closest match.

Some examples below. Just click the links to see converter in action:
Natural Color System S 1002-Y50R CMYK: 0, 3, 6, 11
Natural Color System S 0500-N CMYK: 0, 1, 2, 5
Natural Color System S 2002-Y50R CMYK: 0, 3, 7, 22

You can try various combinations by entering different values in the input form field. Some matches may be better than others, since there are way more CMYK color combinations than NCS color chart can match without much difference visible to the eye. However, this should be sufficient for general reference purposes. Hope that you will find it useful. Let me know what you think via the contact form on this site.
