Processing 4. Change editor window colour?

Processing

Also, from https://github.com/processing/processing4/wiki/Themes:

Processing 4 will have a new set of colors and overall design. The 4.0 alpha 6 has a new set of colors that are not final, but like the rest of the code in the alpha releases, we’re testing things out as we go. You can track progress of the UI design and other theming improvements here.

If you’d like to change the colors, you can specify your own by making a copy of theme.txt and placing it in your sketchbook folder. To find theme.txt :

  • On macOS, right-click Processing.app and select Show Package Contents . Then navigate to Contents → Java → lib, and copy the theme.txt file to your sketchbook.
  • On Windows and Linux, theme.txt can be found in the lib folder that’s part of the Processing download.

Be sure to copy , not move the theme.txt file. After making changes, restart Processing.

Starting with 4.0 alpha 6, all colors (and most fonts) are specified in the theme.txt file. This is a shift from Processing 3, which had some entries stored in preferences.txt and others in theme.txt .
