    Once you have installed it you open it like any other processing tool. You copy the colors array and paste it in your sketch code where you want. for example : //******************** Perceptual ColorPicker colors ******************** color[] pcpColors = new color[5]; pcpColors[0] =#527f74; pcpColors[1] =#777867; pcpColors[2] =#976d5a; pcpColors[3] =#ae624d; pcpColors[4] =#c65141;

    There is a help manual and examples at It is just a color picker...

    Excellent work @rievilo !

    Have you considered adding your tool to the Processing Contributions Manager so that it is available for automatic install?:

  • thanks for the compliment ! I have send a mail to Elie Zananiri for he takes a look. It is him who makes it available for automatic install. I don't know how much time it needs. If you download it from you can unzip the package in the tool directory of your processing folder.
