Converting Rare Book Colours to Usable Colours

Banner of Colour Correction

Not every swatch colour book is created equal. Not all colours are found in every colour book. When converting rare colours from unusable to usable this is a trick you can try.

You will need:

  • The Internet
  • The Pantone book you are using
  • Adobe Illustrator


  • First note down the Pantone colour that is tricky or unlisted
  • In your web browser, go to the Pantone book catalog.
  • Write down the #HEX code of the colour
And there are three options:
  • You can go to a web browser site that will convert the colour back to a Pantone colour


  • You can go to the Edit menu>Convert Colour CMYK
  • Select HEX code colour code option first and copy & paste the colour
  • Then convert it to whatever colour you need it to be based on the downloaded colour books in your program.


  • Go to Edit>Recolor Artwork
  • Select Assign
  • Your selected colour would be in a chart under Current Color, double click on a box with a line through it that’s beside the colour bar and under the New column
  • The colour picker will pop up, in the HEX code area type in the new HEX code
