modifying color theme

I’m trying to modify the current dark colour theme for my needs in the preference dialogue. I don’t find some settings:

  1. change the color of a marked track in editor view (currently red)
  2. change the color of a marked track / channel strip in mixer view (currently red)

Is it possible to export these changes? So when I upgrade I can use these in future versions.

Thanks.

Great. Thanks!

go: Edit>Preferences>Appearance>Colors>Items

find:

  1. gtk_track_header_selected
  2. gtk_bright_indicator
