This package allows the user to easily create their own custom colour tables for use in other Igor plots (either to define colours in image plots, or for colouring traces/data-points).

The interface allows the user to create four distinct types of colour table:

  • Single Hue table
  • Bi-polar (Double Hue) table
  • Multi Hue Category table
  • Hue Blend table

In all of the tables generated, the user is able to specify linear changes in Saturation/Chroma and Lightness/Luminance for each Hue displayed. When creating a Hue Blended table, the Hue also varies along with the Saturation/Chroma and Lightness/Luminance.

Other features include:

  • Ability to specify number of colours in the table
  • Scaling of colour tables to data range of interest
  • Import panel parameters from previously created colour tables
  • Produce plots showing the colour table and the variation in RGB/HSL/HCL for each entry in the colour table

To use this package, open/compile the .ipf, then select the "HCL Colours" sub-menu in the "Jonnys Panels" menu.

Click on the thumbnail at the top right of the package description to see some examples of the colour tables which you can create.
